Abstract Combining metal nanoparticles (NPs) featured with localized surface plasmon resonance (LSPR) metal–organic framework (MOF)‐based photocatalysts is a novel means for achieving efficient separation of electron–hole pairs. Herein, the Au@NH 2 ‐UiO‐66/CdS composites are successfully synthesized by encapsulating Au NPs LSPR into NH ‐UiO‐66 nanocage, further growing CdS on ‐UiO‐66, which exhibits higher photocatalytic activity in hydrogen evolution reaction under visible‐light irradiation than that and CdS, respectively. Transient absorption measurements reveal MOF not only transit station electrons generated from to Au, but also receiver hot plasmonic Au@MOF/CdS composites.

Cu-based catalysts have been widely applied in electroreduction of carbon dioxide (CO2 ER) to produce multicarbon (C2+ ) feedstocks (e.g., C2 H4 ). However, the high energy barriers for CO2 activation on Cu surface is a challenge catalytic efficiency and product selectivity.

In the quest to resolve its current problem of poor selectivity or low density toward one specific product, we propose a feasible strategy develop carbon-encapsulated copper-doped cerium oxide composite (Cu/CeO2@C) one-pot pyrolysis metal–organic framework (MOF) precursors. The optimal Cu/CeO2@C achieves high CH4 Faraday efficiency 80.3% large partial 138.6 mA cm–2. We demonstrate that enhanced activity is attributed synergistic effect Cu/CeO2 in situ-formed with robust channels assist charge transfer.
