The successful synthesis of carbon nitride films plays a crucial role in photoelectrochemical (PEC) water oxidation reactions. However, significant technical challenge is that the contact between g-C3N4 layer and fluorine-doped tin oxide (FTO) substrate suboptimal, as well recombination photogenerated electrons holes grievous, directly affecting effective charge transport overall photocatalytic efficiency. Herein, we fabricated thin photoanode through simple chemical vapor deposition, NiO cocatalyst was modified on surface via electro-deposition followed by calcination, aiming at improving transfer carriers. As expected, effectively suppressed after introducing cocatalyst. Moreover, superior electrical conductivity reduces resistance allows to be rapid injected into electrolyte participate reaction. such, NiO-60s (the deposition time 60 s) exhibits higher photocurrent density much negative onset potential than g-C3N4. which great benefit designing based for PEC
