Due to the burning of fossil fuels, the level of carbon dioxide(CO 2 ) in the atmosphere gradually rises, leading to serious greenhouse effect and environmental problems. Electrocatalytic reduction of CO 2 is currently an efficient way to convert CO 2 to value-added products. Bismuth(Bi)-based nanomaterials have raised great interests due to their excellent activity and high selectivity to electrocatalytic CO 2 reduction. In this review, the fundamental principles of electrochemical CO 2 reduction reaction(CO 2 RR) are introduced at first. Moreover, the recent development of Bi-based electrocatalytic materials including Bi with various nanostructures(nanoparticle, nanosheet, etc.), Bi-based compounds(Bi oxide, bimetal chalcogenide, etc.), and Bi/C nanocomposites are summarized. In the end, the future prospects and challenges of electrocatalysts for CO 2 reduction are discussed.
