Advances in Sn-Based Catalysts for Electrochemical CO2 Reduction

Abstract

HIGHLIGHTS • This review summarizes current developments in the fabrication of tin (Sn)-based electrocatalysts for CO 2 reduction. • Sn-based electrocatalysts are comprehensively summarized in terms of synthesis, catalytic performance, and reaction mechanisms for CO 2 electroreduction. • The remaining challenges and opportunities for Sn-based electrocatalysts in the field of CO 2 electroreduction are briefly proposed and discussed.

Z‐Scheme Photocatalytic Systems for Carbon Dioxide Reduction: Where Are We Now?

“…[58] However,the actual CO 2 reduction process, which comprises multiple steps and intermediates,i sv ery complicated due to the existence of multi-electron kinetics. [59,60] Although amyriad of studies have been done in this area, [61][62][63] further exploration is still needed to unravel the actual mechanism of the CO 2 reduction process.…”

Z‐Schema‐Photokatalysesysteme für die Kohlendioxidreduktion: Wo stehen wir heute?

“…[58] Allerdings ist der jeweilige CO 2 -Reduktionsprozess,der zahlreiche Schritte und Zwischenstufen umfasst, wegen der zu durchlaufenden Vielelektronenkinetik sehr kompliziert. [59,60] Obgleich hierzu unzählige Untersuchungen durchgeführt worden sind, [61][62][63] ist eine weitere Auseinandersetzung mit dem Thema erforderlich, um ein tieferes Verständnis des tatsächlichen Mechanismus des CO 2 -Reduktionsprozesses zu erlangen.…”

Highly Efficient Photoelectrocatalytic Reduction of CO2 to Methanol by a p–n Heterojunction CeO2/CuO/Cu Catalyst

“…However, fossil fuels are a non-renewable energy source, meaning that they will likely be exhausted over the next few hundred years, motivating the development alternative renewable energy technologies (especially solar and wind) as a means of achieving energy supply security. A further downside of using fossil fuels for energy is the associated CO 2 emissions, which directly promote global warming via the greenhouse effect [1][2][3][4]. However, if viewed from another perspective, the CO 2 produced via combustion of fossil fuels or biomass sources represents a cheap C 1 building block (i.e., a resource to be exploited rather than an annoying waste product) [5,6].…”
