Abstract

Electroreduction of CO₂ for formic acid production has been regarded as an efficient option for CO₂ utilization. However, under high current, achieving high selectivity for formic acid is challenging, which cannot meet industrial demands. Herein, we reported a type of Bi/In(OH)₃ (BIO) heterojunction reconstructed from Bi₂S₃/In(OH)₃ during electrochemical process, in which In(OH)₃ was applied to modulate the electronic structure of Bi. This strategy efficiently enhanced the ∗OCHO intermediates adsorption and lead to a decent selectivity towards formic acid under high current density. BIO displays faraday efficiency of formic acid beyond 95 % across a wide range current density of 200–400 mA cm⁻², where the highest value reached 97.7 % at 400 mA cm⁻². This work clarified the mechanism of CO₂ electroreduction to HCOOH on heterojunction, guiding the design of advanced catalysts.

期刊介绍： Progress in Natural Science: Materials International provides scientists and engineers throughout the world with a central vehicle for the exchange and dissemination of basic theoretical studies and applied research of advanced materials. The emphasis is placed on original research, both analytical and experimental, which is of permanent interest to engineers and scientists, covering all aspects of new materials and technologies, such as, energy and environmental materials; advanced structural materials; advanced transportation materials, functional and electronic materials; nano-scale and amorphous materials; health and biological materials; materials modeling and simulation; materials characterization; and so on. The latest research achievements and innovative papers in basic theoretical studies and applied research of material science will be carefully selected and promptly reported. Thus, the aim of this Journal is to serve the global materials science and technology community with the latest research findings. As a service to readers, an international bibliography of recent publications in advanced materials is published bimonthly.
