Nanosized TiO2/Ti photoanodes fabricated by metalorganic chemical vapor deposition (MOCVD) under different deposition temperatures were characterized and applied to the photoelectrocatalytic degradation of model pollutant of phenol. The anode prepared at 773 K was verified in anatase phase with a size about 60 nm and achieved the best photoelectrocatalytic activity, where IPCE could reach as high as 89% and the photoconversion efficiency peaked at 8. 4%. The photoelectrocatalytic degradation of phenol was found well fit a pseudo-first-order kinetics, and kept stable performance in five continuous runs, confirming potential application of the electrode prepared by MOCVD for organic pollutants abatement.

To improve denitrification performance and effective degradation of organic pollutants from micro-polluted groundwater simultaneously, a novel three-dimensional (3D)bio-electrochemical reactor was developed, which introduced activated carbon into a traditional two-dimensional(2D)reactor as the third electrode. The static and dynamic characteristics of the reactor were investigated with special attentions paid to the performance comparison of these two reactors. In the 3D reactor both TOC and nitrate removal efficiency were greatly improved, and the formation of nitrite byproduct is considerably reduced, comparing with that of the 2D reactor. The role of activated carbon biofilm was explored and possible remediation mechanisms for the 2D and 3D reactors were suggested. In such a 3D reactor, the denitrification rate improved greatly to 0.288 mg NO3-N/cm2/d and the current efficiency could reach as high as 285%. Further, it demonstrated good performance stably against variable conditions, indicating very promising in application for groundwater remediation.

An undivided electrochemical system was used to produce hydrogen peroxide on a graphiteepolytetrafluoroethylene cathode. Key factors for cathode preparation, electrochemical activity as well as cathode stability were investigated. The current efficiency for hydrogen peroxide production wasw61e78% over a wide pH range(3e11)which decayed insignificantly after 10 times reuse. The influence of Na2SO4, pH, cathodic potential, initial dye concentration and ferrous ion concentration on decolorization were systematically studied. The results show that the presence of ferrous ion improved color removal greatly, at 0.2 mM Fe2

【期刊论文】Degradation of cationic red X-GRL by electrochemical oxidation on modified PbO2 electrode

This work investigated the degradation of an azo dye, cationic red X-GRL, by electrochemical oxidation on a novel PbO2 anode modified by fluorine resin. The influences of treatment time, electrolyte concentration, current density, temperature and initial dye concentration on the color and COD removal were critically examined. This process showed a high current efficiency and competitive energy consumption for effective treatment of dye wastewater containing a certain salt content. In the investigated electrolyte concentrations, high salt content exhibited insignificant promotion on the color and COD removal but favored the decrease of energy consumption. During treatment, the current efficiency decreased but the energy consumption increased with treatment time, thus, this method was more suitable for the pretreatment of high-concentrated azo dye wastewater. Based on the degradation intermediates identification, a simplified degradation pathway for cationic red X-GRL was proposed.

This work compared the degradation behaviors of an azo dye, cationic red X-GRL, by three clean advanced oxidation processes: wet oxidation(WO), electrochemical oxidation(EO)and wet electrochemical oxidation(WEO). It was found that the WO process was readily to remove color while the EO process was prone to decompose pollutants. Integrated with the advantage of two processes, the WEO process posed synergetic effects for both efficient removal of color and COD. Even at the low temperature of 120 ◦C, the color could be almost completely removed at 60 min, and the COD removal was about 43. 2% at 120 min, which was greatly protomted from that by WO at similar conditions(about 7. 8%). And it demonstrated a better performance under a reduced temperature and a wider dye concentration range, representing the most promising alternative for environmental application among the three processes. The main degradation products for three processes were detected and a simplified five-stages degradation pathway was suggested, which indicated that the WEO process mineralized much more completely than the other two processes.

【期刊论文】The role of oxygen in the degradation of p-chlorophenol by Fenton system

The role of oxygen in the degradation pathway of 4-CP by Fenton system was investigated in this paper. The degradation of 4-CP, changes of Fenton reagent’s concentration and formation of the intermediates in Fenton/O2 system were respectively compared with those in Fenton/N2 system. The result showed that both 4-CP degradation and CODcr removal in Fenton/O2 system were prior to those in Fenton/N2 system. Investigation intothe intermediates suggested that the presence of oxygen impeded the formation of 4-chlorocatechol and accelerated the production of organic acids such as maleic acid, fumaric acid, acetic acid and oxalic acid. Based on the changes of reaction substances and the intermediates, the degradation mechanism of 4-CP by Fenton system in the presence of O2 was suggested. The dissolved oxygen competed against hydroxyl radical to react with ortho-parachlorohydroxyphenyl radical(ClHP•)producing ortho-parachlorophenolperoxyl radical(ClPP•)and impeding the generation of 4-chlorocatechol. In addition, the reaction of oxygen with(Cl)PP radical increased the extent of benzene ring cleavage, producing more aliphatic organic acids. This study makes clear the mechanism of Fenton/O2 system and thus, it is helpful to establish the kinetic model and provide a good guide to the treatment of real wastewater.

TiO2 photocatalyst (P-25) (50mg L-1)was tentatively introduced into pulsed high-voltage discharge process for non-thermal plasma-induced photocatalytic degradation of the representative mode organic pollutant parachlorophenol (4-CP), including other compounds phenol and methyl red in water. The experimental results showed that rate constant of 4-CP degradation, energy efficiency for 4-CP removal and TOC removal with TiO2 were obviously increased. Pulsed high-voltage discharge process with TiO2 had a promoted effect for the degradation of these pollutants under a broad range of liquid conductivity. Furthermore, the apparent formation rates of chemically active species(e. g., ozone and hydrogen peroxide)were increased, the hydrogen peroxide formation rate from 1.10

【期刊论文】An improved UV/Fe3+ process by combination with electrocatalysis for p-nitrophenol degradation
周明华, Minghua Zhou*, Lecheng Lei

p-Nitrophenol(PNP)was investigated as a model pollutant under the improved UV/Fe3+ process by combination with electrocatalysis. In the individual UV/Fe3+ process, PNP degradation rate was dependent on Fe(III)concentration and decreased during degradation due to the depletion of ferric ion and thus it was very difficult to reach the quick mineralization of organics. These drawbacks could be significantly overcomed in the modified UV/Fe3+ process, and synergetic effects for PNP and COD removal were observed at two investigated Fe(III)concentrations. The enhancements on the degree of conversion for PNP and COD in presence of 0.5mM Fe(Ⅲ)were 184% and 242%, respectively, and PNP of initial concentration of 1.0mM could be completely removed within 1 h. Thus such a process would be very attractive to the rapid mineralization of the biorefractory compounds for wastewater treatment. The possible reasons for the synergetic effects were the electrochemical regeneration of ferric ion and the role of the oxygen that formed on the anode. Based on degradation intermediates identification and synergetic effect probe, a general reaction pathway for PNP degradation in the improved process was proposed.

Anatase TiO2 coatings on highly porous activated carbon were prepared by a novel method—atmospheric pressure metal organic chemical vapor deposition(AP-MOCVD). At a source temperature of 423 K, the TiO2 particles were mostly coated on the external surface of activated carbon. These particles were well dispersed with their sizes ranging from 10 to 50 nm. The optimum loading of TiO2 was found to be 12 wt%. The TiO2 photocatalysts so prepared behave similarly to that of the pure commercial TiO2 powder. The activated carbon supported TiO2 catalyst could be easily separated from the treated water with its catalytic performance maintained even after 10 cycles, indicating that the TiO2 coating was stable. It was observed that TiO2 supported on activated carbon had a high capacity to mineralize pollutants. Consequently, activated carbon supported TiO2 by AP-MOCVD is a promising photocatalyst for the photodegradation of pollutants in water.
