Alcohols (methanol, ethanol and isopropanol) have been found to affect the heterogeneous nucleation and growth of Ag nanoparticles onto oxygenated mesoporous carbon support and the corresponding catalytic property of Ag/Carbon nanocomposite in nitroaromatics (4-nitrophenol and 2-nitroaniline) reduction reactions. Ethanol exhibits unique capability to regenerate reactive CH2OH groups on carbon surface...
g-C3N4/Ag-polypyrrole (PPy) visible-light photocatalysts were prepared in a simple way, in which g-C3N4 was decorated with Ag nanoparticles, and covered by PPy layer. Their photoactivity was evaluated by degradation of rhodamine B. Compared with g-C3N4, g-C3N4/Ag and g-C3N4/PPy, the enhanced photocatalytic activity was obtained and explained according to the improvement of visible-light absorption...
