Cd0.5Zn0.5S solid solutions were prepared by hydrothermal method and co‐precipitation method. The synthesized materials were characterized by means of X‐ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) surface area measurement and ultraviolet–visible diffuse reflectance spectra (UV–Vis DRS). The photocatalytic activity was tested in the reaction of hydrogen evolution from aqueous solutions of glycerol under visible light irradiation (λ ≥ 420 nm). Zn0.5Cd0.5S‐G prepared by co‐precipitation method with glycerol as solvent exhibits higher photocatalytic activity. This can be due to Zn0.5Cd0.5S‐G possessing higher surface area, which is beneficial to the adsorption of electron donor on catalyst surface. Glycerol improves notably photocatalytic hydrogen evolution with its simultaneous degradation. The possible mechanism of photocatalytic reaction for hydrogen evolution with simultaneous glycerol degradation was discussed preliminary. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 141–148, 2016

In this thesis, stable nanoMgO particles were prepared by precipitation process, using analytical pure MgCl2·6H2O and NH3·H2O as the raw materials, which MgCl2 as the source of magnesium and NH3·H2O as the precipitating agent. The dispersant of PAAS and SHMP in appropriate dosage was also needed. The nanoMgO particles were characterized by using techniques such as Infrared Spectroscopy, Absorbance Determination, Scanning Electron Microscopy and tested by Laser Particle Size Analyzer. The nanoMgO finishing agent is prepared in the condition of ultrasonic oscillation by optimized processes which involve the choosing of appropriate dispersant. Finally, the good UV protection and antibacterial silk fabrics was obtained through functional finishing by impregnating process on silk fabrics under treated by peregal-O. This work lays a foundation for the research and application of nanoscale finishing agent preparation with the low cost. The results showed that the stability of prepared nanoMgO particles is considerable, the durability of the finished fabrics is satisfactoried.
