Snowflake-like Cu-BDC-NH₂/Cu₅₈S₃₂ Binary Nanohybrid for H₂ Evolution and O₂ Reduction

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(7), P. 7365 - 7380

Published: April 2, 2024

In this study, a nonstoichiometric roxbyite (Cu58S32) phase with nanoplate (np) and snowflake (sf) morphologies was prepared under solvothermal conditions by varying the sulfur source. The Cu58S32 (CS) subsequently used as host matrix well copper source for in situ construction of Cu-BDC-NH2/Cu58S32 (CSM) nanohybrid materials. regulated growth Cu-MOF nanoplates over well-crystalline radially symmetric hexagonal dendritic structure led to formation an n–p heterojunction large interfacial contact area. Comprehensive characterizations nanohybrids unveiled improved light harvesting properties, electrochemically active surface areas, synergistic charge mobilization between constituent semiconductor surface-aligned ultrathin nanosheets contained three distinct types coordinated metal sites involving Cu(II) dimers paddle wheel monomeric distorted ligand environment. optimal CSM(sf) hybrid displayed photocatalytic activity toward H2 evolution (9343 μmol g–1 h–1) O2 reduction (2339 solar simulation reaction rates 14–20 times greater than pure semiconductors. strong hydrophilic character, morphology, high redox ability photogenerated electrons through S-scheme transfer mechanism accounted
