MOF-templated and phase-controlled synthesis of CdS hierarchical nanostructures for visible-light-driven photocatalytic applications

Abstract Developing delicate methods to synthesize well-controlled nanostructures is diffusely recognized as a potent tool enhance photocatalysts’ performances in various photoreactions. Herein, phase-controlled CdS hierarchical were synthesized using MOF-templated strategy, where Co-MOF nanospheres used the starting material, followed by two steps of sulfidation and cation exchange. By rational collocations solvent Cd source exchange process, cubic hollow hexagonal can be obtained, respectively. Further tests revealed that during photo-reduction reaction CO 2 , former exhibited high performance producing H . At same time, latter showed superior activity selectivity for generation, which embodies potential synthesis selective applications with disparate phases.
