| Summary: | InP microcrystal was successfully synthesized <i>via</i> a facile hydrothermal route, and then Ag nanoparticles were loaded on the surface of InP microcrystal using UV lamp to reduce silver versions. The as-prepared composites were characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM). The results show that Ag/InP composite is composed of lots of spherical microcrystals with a size of 500nm and Ag nanoparticles with a diameter of 20 nm loaded uniformly on the surface of cubic phase InP microspheres,the surface is rough. Using Congo red as model organic pollutant, the photo-catalytic performance of Ag/InP microspheres is further detected by fluorescence and UV-vis spectra. It is found that the as-prepared composite exhibits a superior photo-catalytic degradation activity as compared to InP, which might be the effective separation of electrons and holes after Ag nanoparticles loaded on the surface of InP microspheres.In addition,the photo-catalytic performance of Ag/InP microspheres with different Ag loads was studied,and the results show that when the loading is 73.3%,the photocatalytic activity of the product is the best,and the degradation rate is 64%. |
