WebThe rational design of interfacial contacts plays a decisive role in improving interfacial carrier transfer and separation in heterojunction photocatalysts. In Z-scheme photocatalysts, the recombination of photogenerated electron–hole pairs is prevented so that the redox capacity is maintained. Here, one-dimensional graphitic carbon nitride (g … WebArrangement of electron carriers according to their redox potential. The ability of a substance to give up or take up electron depends upon its redox potential value. Substance with low redox potential will lose electrons easily and substance with high redox potential will gain electrons. Suggest Corrections. 1.
