Recent advances in transition-metal-mediated electrocatalytic CO(2) reduction: from homogeneous to heterogeneous systems

Published: 1 December 2017Recent advances in transition-metal-mediated electrocatalytic COGlobal climate change and increasing demands for clean energy have brought intensive interest in the search for proper electrocatalysts in order to reduce carbon dioxide (CO₂) to higher value carbon products such as hydrocarbons. Recently, transition-metal-centered molecules or organic frameworks have been reported to show outstanding electrocatalytic activity in the liquid phase. Their d-orbital electrons are believed to be one of the key factors to capture and convert CO₂ molecules to value-added low-carbon fuels. In this review, recent advances in electrocatalytic CO₂ reduction have been summarized based on the targeted products, ranging from homogeneous reactions to heterogeneous ones. Their advantages and fallbacks have been pointed out and the existing challenges, especially with respect to the practical and industrial application are addressed. reduction: from homogeneous to heterogeneous systemsDa-Ming Feng, Yun-Pei Zhu, Ping Chen and Tian-Yi M
