Ag/g-C3N4 光催化剂通过快速微波辅助多元醇工艺合成。表征结果显示，直径为几纳米的单分散Ag纳米颗粒紧密附着在g-C3N4的边缘。 Ag/g-C3N4光催化剂中Ag纳米颗粒的存在增强了可见光吸收并抑制了光生电子/空穴对的复合。 Ag/g-C3N4 光催化剂对罗丹明 B 降解表现出优异的可见光响应光催化活性。还讨论了Ag/g-C3N4光催化剂的可见光诱导光催化机理。
Ag/g-C3N4photocatalysts were synthesized by a rapid microwave-assisted polyol process. The characterization results showed monodisperse Ag nanoparticles with diameters of a few nanometers closely attached to the edges of g-C3N4. The presence of Ag nanoparticles in Ag/g-C3N4photocatalysts enhanced the visible-light absorption and suppressed the recombination of photogenerated electron/hole pairs. The Ag/g-C3N4photocatalysts exhibited the superior visible-light responsive photocatalytic activity for rhodamine B degradation. The mechanism of visible-light induced photocatalysis over Ag/g-C3N4photocatalysts was also discussed.
