“…At the same time, biochar can inherit the morphology and porous structure of natural biomass and realize the self-doping of elements (P, N, etc.) to improve the use of light, enhance the mass transfer, and raise the dispersion of the loaded metal. , Excitingly, biochar can be directly used to realize the composite with other substances for improving the electron transfer. − However, the current research on biochar-based photocatalysts is mainly focused on the degradation of organic pollutants, ,, and there is less research in photocatalytic hydrogen production from water. ,,,− Moreover, it is difficult to achieve a high catalytic effect using a simple carbon material.…”
