摘要：

The solar-driven photocatalytic reduction of CO2 (CO2RR) into chemical fuels is a promising route to enrich energy supplies and mitigate CO2 emissions. However, low catalytic efficiency and poor selectivity, especially in a purewater system, hinder the development of photocatalytic CO2RR owing to the lack of effective catalysts. Herein, we report a novel atom-confinement and coordination (ACC) strategy to achieve the synthesis of rare-earth single erbium (Er) atoms supported on carbon nitride nanotubes (Er1/CNNT) with a tunable dispersion density of single atoms. Er1/CNNT is a highly efficient and robust photocatalyst that exhibits outstanding CO2RR performance in a pure-water system. Experimental results and density functional theory calculations reveal the crucial role of single Er atoms in promoting photocatalytic CO2RR. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
