A series of Cd1−xZnxS (x=0-0.92) photocatalysts were prepared by coprecipitation method and were calcined at 723K under N2 atmosphere. X-ray diffraction patterns results showed that the solid solution of Cd1-xZnxS were formed between ZnS and CdS. UV-Vis spectra indicated that the absorption edges of Cd1-xZnxS were red-shifted as the value of x decreased. The band gaps of the photocatalysts were estimated to be between 2.20-3.12 eV (x=0-0.92) from the onsets of the absorption edges and almost showed linear variation with x increasing. The position of conduction band for solid solution is shifted towards more negative potential as compared to that of CdS. The hydrogen productions of Cd1-xZnxS (x=0-0.92) by splitting water photocatalytically under ultraviolet and visible light irradiation were carried out in an inner-irradiation type reactor. The results indicated that the photocatalyst of Cd0.62Zn0.16S has the highest rate of hydrogen evolution with the quantum efficiency of 2.17%and 0.60%under ultraviolet and visible light irradiation, respectively. It has been considered that the crystallite size, (101) plane and band gap for the Cd1-xZnxS solid solutions have a strong influence on the efficiency of hydrogen production capability for water splitting.

Non-woven poly (lactic-co-glycolic acid) (PLGA) nanofibers were prepared by electrospinning technology. The morphology of the electros pun fibers was observed using scanning electron Microscopy (SEM) and the fiber diameter was calculated. Primary human dermal fibroblasts (HDFs) were cultured to evaluate the biocompatibility of the electrospun PLGA nanofibers. The results of MTT testing and SEM showed that the PLGA nanofibers have the morphology of interwoven and highly porous structure and can support the attachment and proliferation of HDFs. It is can be expected to be a potential scaffold material for tissue engineering.
