The advancement in the treatment technology for wastewater containing recalcitrant pollutants to lower the overall cost and time of the treatment processes is the prime demand. Biochar (BC) based photocatalyst have proved their potential application in the photo-degradation of a wide range of organic pollutants. The structural and chemical properties of the BC enhance the efficacy of photocatalyst, improving its optical properties with increased stability. This review gives an overview of the progress that occurred during the last five years in BC-based photocatalyst for degradation of recalcitrant organic waste in the aqueous system, emphasizing the role of BC in the photocatalytic performance with a brief discussion regarding the various sources of BC and different strategies used to modify the BC. Further, the critical challenges are discussed, which would be confronted during the scaling up and real-time application in wastewater treatment.
提高处理含有难降解污染物的废水的技术水平，降低处理过程的总成本和时间，是当务之急。基于生物炭（BC）的光催化剂已被证明在光降解各种有机污染物方面具有潜在的应用。BC 的结构和化学性质增强了光催化剂的功效，提高了其光学性能和稳定性。本文综述了过去五年中在基于 BC 的光催化剂用于降解水相中难降解有机废物方面的进展，强调了 BC 在光催化性能中的作用，并简要讨论了 BC 的各种来源和用于修饰 BC 的不同策略。此外，还讨论了在废水处理中扩大规模和实时应用所面临的关键挑战。
