CO2的光催化还原是一个多电子、多转化的反应过程，其效率受催化材料表面电子传递途径的影响。在这里，Pt单原子锚定的非晶ZrO 2纳米线（Pt SA/ZrO 2）是一种高效的CO2还原光催化剂。该助催化剂表现出上级的CO产率（16.61 mmol/g/h）和选择性（97.6%），优于同行和大多数以前报道的ZrO 2基光催化剂。无定形性质赋予材料固有的丰富缺陷（例如氧空位），ZrOPt电荷桥允许快速光电子转移，共同有助于增强CO2还原性能。我们预计，基于锚定单原子在无定形纳米基板的设计策略将激发先进的光催化剂的进一步发展。(c)2021爱思唯尔有限公司保留所有权利。
The photocatalytic reduction of CO2 is a reaction that involves multi-electron and multiconversion processes, and its efficiency is strongly affected by the electron transport pathways on the surface of the catalytic material. Here, Pt single-atom-anchored amorphous ZrO2 nanowires (Pt SA/ZrO2) are fabricated as an efficient photocatalyst for CO2 reduction. The co-catalyst exhibited a superior CO yielding rate (16.61 mmol/g/h) and selectivity (97.6%), outperforming counterparts and most of previously reported ZrO2-based photocatalysts. The amorphous nature endows the material with inherent abundant defects (e.g. oxygen vacancies), and ZrOPt charge bridges allow rapid photoelectron transfer, jointly contributing to the enhanced CO2 reduction performance. We anticipate that design strategies based on anchoring single atoms on amorphous nanosubstrates will inspire further development of advanced photocatalysts. (c) 2021 Elsevier Ltd.
