的XRD测试图,由图1可见,样品2.5%Nb-Mo/g-C 3 N 4 和样品0.5%Nb-Mo/g-C 3 N 4 在13.1°和27.3°有二个衍射峰,与纯的g-C 3 N 4 衍射峰相符合,掺杂的g-C3N4催化剂,主峰仍然保留,说明晶体结构没有改变。在所掺杂的g-C3N4材料中都未观察到Nb和Mo的化合物,表明Nb和Mo以离子形式嵌入g-C3N4晶面内。
TEM, XRD, XPS, UV-vis diffuse reflectance spectroscopy, photo-electrochemistry and PL tests were carried out to characterize the structures, morphologies and carrier separation efficiencies of products. Benefiting from the boosted visible light absorption capability, reduced charge transfer resistance and ...
