Abstract
- Exploring new catalytic strategies for achieving efficient CO2 hydrogenation under mild conditions is of great significance for environmental remediation. Herein, a composite photocatalyst Zr‐based MOF encapsulated plasmonic AuPt alloy nanoparticles (AuPt@UiO‐66‐NH2) was successfully constructed for the efficient photothermal catalysis of CO2 hydrogenation. Under light irradiation at 150 °C, AuPt@UiO‐66‐NH2 achieved a CO production rate of 1451 μmol gmetal−1 h−1 with 91 % selectivity, which far exceeded those obtained by Au@Pt@UiO‐66‐NH2 with Pt shell on Au (599 μmol gmetal−1 h−1) and Au@UiO‐66‐NH2 (218 μmol gmetal−1 h−1). The outstanding performances of AuPt@UiO‐66‐NH2 were attributed to the synergetic effect originating from the plasmonic metal Au, doped active metal Pt, and encapsulation structure of UiO‐66‐NH2 shell. This work provides a new way for photothermal catalysis of CO2 and a reference for the design of high‐performance plasmonic catalysts. [ABSTRACT FROM AUTHOR]
