A eutectic salt mixture (LiCl/ZnCl2) as a template plays a dual role by rendering sufficient surface area and a source of Zn2+ for in situ formation of ZnS. The resulting composites as an anode exhibit superior performance compared to pure ZnS.
BiOCl/(BiO)2CO3 composites with reactive exposed {001} facets have been synthesized by a one-step in situ solvothermal method. The synergistic effect of type-II band alignment and exposed high-energy facets enhances photocatalytic activity.
