The hydrogen production from photocatalytic water decomposition is one of the best approaches that convert solar energy to hydrogen energy. At present, the hydrogen production from photocatalytic water decomposition has a low efficiency. In order to determine a valuable hydrogen production process from photocatalytic water decomposition in the aspect of energy conversion, the concept of critical conversion efficiency of light energy is proposed in this paper. Critical conversion efficiency of light energy is defined as the conversion efficiency of light energy when the hydrogen energy output is equal to an equivalent energy input of the system. The criterion introduced is that only if the conversion efficiency of light energy is greater than the critical one, an energy profit can be achieved in a system. A hypothetical system with 20,000 tons annual hydrogen production by using Na2S/Na2SO3 as the sacrificial reagent is analyzed and calculated in this paper to determine the critical conversion efficiency of light energy by means of energy balance, cumulative exergy balance, and emergy balance, respectively. The results show that the critical conversion efficiency of light energy determined by emergy balance is the most reasonable, which gives the figure around 15%.

The CdS/TiO2NTs composite was prepared by a simple two-step chemical solution routes to directly transfer trititanate nanotubes to TiO2NTs and simultaneously coupled with CdS nanoparticles. The results of XRD, TEM, Diffuse reflectance UV–Visible absorption spectra revealed that the CdS nanoparticles were homogeneously embedded on the surface of TiO2NTs and the absorption spectrum of TiO2NTs was extended to visible region. The activity of hydrogen production by photocatalytic water decomposition for the CdS/TiO2NTs composite was examined under visible light irradiation (λN400 nm) and the quantity of H2 evolution was ca. 1708 μL/g for 6h.
