Enhanced Photocatalytic Decomposition Of Organic Dye Over A Novel Biochar/Rose-Like Biocl Composite Photocatalysts

Biochar, as a new carbon source, has attracted more and more people's attention. In addition, the new catalyst bismuth oxychloride has been widely used for photocatalytic degradation, not only due to the special structure, high stability, but also has excellent electrical and optical properties. However, BiOCl can not be excitation under visible light irradiation on account of its broad band gap. In this work, BiOCl is loaded on pine needle biochar to further improve the photocatalytic degradation efficiency. When the mass ratio of BiOCl and biochar at 3: 4, it has exhibited the highest degradation efficiency.
