After millions of years of evolution,species in nature have structures and complex elements that are difficult to synthesize artificially.Moreover,these fine structures and compositions are often beneficial to improve the photocatalytic performance.Therefore,various materials with special morphology,pore structure and element composition derived from biomass have emerged and are widely used.This mini review focuses on the preparation of bio-inspired materials and their current status in photocatalytic hydrogen production.Hopefully,this will bring new perspectives to researchers and make them learn more about the advantages of “learning from nature” and pay more attention to the green design of material structures.
