Waste-derived materials have been gaining increased attention in recent years due to their great potential and environmentally friendly nature. Several contributions in the literature have covered the advances achieved so far in this area. Nonetheless, to the best of our knowledge, no review has been dedicated specifically to waste-derived or templated photocatalytic materials. Both photocatalysis and (bio)waste-inspired design yield materials of a remarkably green nature. Therefore, the partnership between them may open promising possibilities for both waste valorization and photocatalytic processes, which in turn will lead to sustainable development globally, with the potential for full utilization of renewable energy sources such as biomass and sunlight. Several photocatalytic waste-derived materials, synthetic procedures, and applications will be described throughout this work, including waste-derived/templated TiO₂, ZnO, and metal sulfide materials. Special attention will be given to biomass-inspired carbonaceous materials, including carbon quantum dots and graphitic carbon nitride (g-C₃N₄).

废物来源的材料：光催化的机会

近年来，废物源材料由于其巨大的潜力和环境友好性质而受到越来越多的关注。文献中的几篇著作涵盖了迄今为止在该领域取得的进展。但是，就我们所知，还没有专门针对废物衍生或模板化的光催化材料进行审查。光催化和（生物）废物启发的设计均可产生具有明显绿色特性的材料。因此，它们之间的伙伴关系可能为废物增值和光催化过程打开广阔的前景，而这反过来将导致全球可持续发展，并具有充分利用生物质和阳光等可再生能源的潜力。几种光催化废物衍生材料，合成程序，₂，ZnO和金属硫化物材料。将特别注意受生物质启发的碳质材料，包括碳量子点和石墨氮化碳（gC ₃ N ₄）。
