Enhanced n-Hexane Degradation Performance of PCN/Bi0-BWO/Zn(CH3COO)2-ACF with Z-Scheme Heterojunction: Synergistic Effect of Photocatalysis and Adsorption

PCN/Bi 0 -BWO/Zn(CH 3 COO) 2 -ACF composite was compounded for the removal of n-hexane in this paper. Characterization results show that the composite was successfully prepared and the light response ability of the catalyst was improved. The photocatalytic properties of the composite were also tested; the removal rate of PCN/Bi 0 -BWO/Zn(CH 3 COO) 2 -ACF composite can reach more than 85% in 360 min. The main reason for the improvement of the performance of the composites was that the addition of phosphorus and the formation of Z-scheme heterojunction increased the efficiency of electron–hole separation on the surface of the catalyst.
