Ultrasound-assisted room-temperature in situ precipitation synthesis of BC doped Bi4O5Br2 for enhanced photocatalytic activity in pollutants degradation under visible light

A novel photocatalyst based on the integration of biochar (BC) with Bi4O5Br2 using an ultrasound-assisted room-temperature in situ precipitation method was facilely prepared. The morphological, optical, structural and photoelectrochemical characteristics of the composites were studied via various techniques. The photocatalytic result confirmed that the BC/Bi4O5Br2 photocatalyst with 1.5 wt% of Bi4O5Br2 has achieved 99.98% removal efficiency in...
