| 13 | Efficient CO_(2)Reduction to Formate on CsPbI_(3) Nanocrystals Wrapped with Reduced Graphene Oxide显示文摘Transformation of greenhouse gas(CO_(2))into valuable chemicals and fuels is a promising route to address the global issues of climate change and the energy crisis.Metal halide perovskite catalysts have shown their potential in promoting CO_(2)reduction reaction(CO_(2)RR),however,their low phase stability has limited their application perspective.Herein,we present a reduced graphene oxide(rGO)wrapped CsPbI_3 perovskite nanocrystal(NC)CO_(2)RR catalyst(CsPbI_3/rGO),demonstrating enhanced stability in the aqueous electrolyte.The CsPbI_3/rGO catalyst exhibited>92%Faradaic efficiency toward formate production at a CO_(2)RR current density of~12.7 mA cm^(-2).Comprehensive characterizations revealed the superior performance of the CsPbI_3/rGO catalyst originated from the synergistic effects between the CsPbI_3 NCs and rGO,i.e.,rGO stabilized theα-CsPbI_3 phase and tuned the charge distribution,thus lowered the energy barrier for the protonation process and the formation of~*HCOO intermediate,which resulted in high CO_(2)RR selectivity toward formate.This work shows a promising strategy to rationally design robust metal halide perovskites for achieving efficient CO_(2)RR toward valuable fuels. | Minh Tam Hoang Chen Han Zhipeng Ma Xin Mao Yang Yang Sepideh Sadat Madani Paul Shaw Yongchao Yang Lingyi Peng Cui Ying Toe Jian Pan Rose Amal Aijun Du Tuquabo Tesfamichael Zhaojun Han Hongxia Wang | 2023 | Nano-Micro Letters2023，15，10： | 1 |
