Ag 2 S 2 O 7 /Ag 2 O纳米颗粒异质结构的制备及其太阳光全光谱光催化降解应用(英文)
发布时间:2023-08-05 17:13
Ag2O是优良的感光材料,很少作为光催化材料,而常被用作光催化材料的共催化剂.此外,由于Ag2O禁带宽度窄,且可有效吸收近红外光,因而不能用于全太阳光谱的光催化应用中.同时很少被用作NIR催化剂.本文中不仅研究了纳米Ag2O颗粒的UV-Vis光催化性能,而且还系统探究了其NIR光催化活性.由于在紫外线和可见光的照射下,Ag2O纳米颗粒易发生光还原失活,因而对Ag2O表面硫化处理,使其表面上生长Ag2S2O7层以形成Ag2S2O7/Ag2O异质结,探究了该异质结UV-Vis光催化活性及其光催化循环稳定性;同时,考察了其近红外光催化及其重复使用性能.利用沉淀法成功制备了Ag2O纳米颗粒,并通过在其表面部分硫化处理得到Ag2S2O7,成功构筑Ag...
