Abstract

Electrochemical CO2 reduction is a viable, economical, and sustainable method to transform atmospheric CO2 into carbon-based fuels and effectively reduce climate change and the energy crisis. Constructing robust catalysts through interface engineering is significant for electrocatalytic CO2 reduction (ECR) but remains a grand challenge. Herein, SnO2/Bi2O2CO3 heterojunction on N,S-codoped-carbon (SnO2/BOC@NSC) with efficient ECR performance was firstly constructed by a facile synthetic strategy. When the SnO2/BOC@NSC was utilized in ECR, it exhibits a large formic acid (HCOOH) partial current density (JHCOOH) of 86.7 mA·cm−2 at −1.2 V versus reversible hydrogen electrode (RHE) and maximum Faradaic efficiency (FE) of HCOOH (90.75% at −1.2 V versus RHE), respectively. Notably, the FEHCOOH of SnO2/BOC@NSC is higher than 90% in the flow cell and the JHCOOH of SnO2/BOC@NSC can achieve 200 mA·cm−2 at −0.8 V versus RHE to meet the requirements of industrialization level. The comparative experimental analysis and in-situ X-ray absorption fine structure reveal that the excellent ECR performance can be ascribed to the synergistic effect of SnO2/BOC heterojunction, which enhances the activation of CO2 molecules and improves electron transfer. This work provides an efficient SnO2-based heterojunction catalyst for effective formate production and offers a novel approach for the construction of new types of metal oxide heterostructures for other catalytic applications.

Abstract

The photocatalytic reduction of carbon dioxide (CO2RR) into value-added chemical products is a promising way to enrich energy supply and reduce CO2 emission. The proposal of a high-efficiency, low-cost and easy-to-operate photocatalyst is an essential segment for promoting the CO2RR from small-scale laboratory examination to large-scale industrial application. Herein, we first come up with a Co photocatalyst with isolated Co single atoms anchored on a commercial super conductive carbon black (Co-SA@SP-800) and employ it to effectively boost the photocatalytic CO2 reduction reaction. Large scale production of the Co-SA@SP-800 catalyst can be achieved by a simple and practical adsorption–pyrolysis method. The as-prepared Co-SA@SP-800 catalyst presents remarkable photoactivity and CO selectivity with a CO production yield of 1.64 × 104 μmol g−1 and a CO selectivity of 84.2% after 2 h of UV illumination in a heterogeneous system, and significantly outperforms other reference samples and most of the other efficient photocatalysts reported recently toward the conversion of CO2. In situ diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy was carried out to investigate the reaction intermediates during the photocatalytic CO2RR. Control experiments and theoretical calculations revealed that the isolated single atomic Co–N4 sites greatly lower the energy barrier for the desorption of CO* during CO2-to-CO conversion, while suppressing H2 evolution in the competing water splitting reaction. This work provides valuable new insights for rationally designing and synthesizing high-performance single atom catalysts for photocatalytic CO2 reduction with ease of large-scale production.
