Biochar photocatalyst
WebNov 20, 2024 · The CBi photocatalyst with the 20 wt% biochar (CBi-20%) exhibited an optimal photodegradation ability for SA. The degradation rate of SA was approximately 97.0% after 7 h of visible light irradiation, and the removal rate of total organic carbon (TOC) was as high as 83.4%, indicating an excellent mineralization ability. WebJun 5, 2024 · When biochar is added to form a composite, it can promote light absorption . However, there is an ideal biochar/photocatalyst ratio, and this varies according to the source of the biochar. An excess of biochar leads to a reduction in photocatalytic efficiency because it blocks the light that reaches the surface of the catalyst [113, 133].
