Abstract

Charge separation plays a pivotal role in enhancing the photocatalytic activity of semiconductors for the degradation of organic pollutants and reduction of hexavalent chromium. In this context, the influence of the (001) facet of BiOCl on these processes was investigated. A multi-layered erythrocyte-like Bi-BTC was synthesized via high-power ultrasonication, with BiOCl incorporated into its interlayer. BiOCl crystallized along the (001) plane, exposing this facet, which facilitated effective charge separation. Photogenerated electrons participated in reduction reactions, while holes drove oxidation reactions on the (001) surface. The photocatalytic performance was optimized at a 5 % BiOCl doping level, achieving 98.8 % RhB degradation in 50 min and 97.4 % hexavalent chromium reduction in 80 min. These findings highlight the importance of the (001) crystalline facet in efficient charge separation and offer insights for the design of advanced photocatalysts.
