论文部分内容阅读

Metal oxide or metal nanodots modified g-C3N4 was fabricated using a facile evaporation-annealing method.The effect of metal oxide or metal nanodots decoration on the rate of visible-light(λ ＞ 420 nm)photocatalytic activity was studied by hydrogen production from triethanolamine(TEOA)aqueous solutions.[1-3] The highest photocatalytic activity was observed on Cu(0.05wt％)/g-C3N4 with the hydrogen evolution rate of 241.3 μmolh-1g-1,which exceeded that of pure g-CaN4(141.6 μmolh1g-1)by more than 70％.The mechanism for the enhanced visible-light photocatalytic activity of g-C3N4 decorated with metal oxide or metal nanodots was carefully investigated.
