Abstract:
Large amounts of antibiotics are released into the natural environment, posing a potential threat to ecosystems and human health. Biochar photocatalytic materials usually have the advantages of high pollutant removal efficiency, environmental friendliness, and low energy consumption, which have a promising application in the efficient removal of antibiotics from water. The structural and chemical properties of the biochar (BC) enhancing improve the light absorption performance, degradation activity and stability of photocatalysts. A large amount of antibiotics are released into the natural environment, posing a potential threat to ecosystems and human health. Biochar photocatalytic materials usually have the advantages of high pollutant removal efficiency, environmental friendliness, and low energy consumption, and have broad application prospects in efficiently removing antibiotics from water. The structure and chemical properties of biochar enhance the light absorption performance, degradation activity, and stability of photocatalysts.The advantages of biochar photocatalytic materials over biochar adsorption as well as nanoparticle photocatalytic degradation of pollutants in water were reviewed, and three methods of preparing biochar photocatalytic materials were summarized, namely sol-gel method, ultrasonic method and hydrothermal method, as well as the research progress of composite materials applied to the degradation of antibiotics in water. The mechanism of biochar photocatalytic materials to degrade pollutants in water was introduced. Finally, a summary and outlook were made on the future research directions and development prospects of biochar photocatalytic materials, pointing out that the design of biochar photocatalytic materials used in scale and practical application should be the research focus in this field in the future.
