Copper-based homogeneous and heterogeneous catalysts for electrochemical water oxidation
Water oxidation is currently believed as the bottleneck in the field of electrochemical water splitting and artificial photosynthesis. Enormous efforts have been made in the exploration of water oxidation catalysts (WOCs), including homogeneous and heterogeneous catalysts. Recently, Cu-based WOCs were widely developed because of its high abundance, low cost, and biologically relevant. However, to the best of our knowledge, no overview has been made so far for this type of catalysts, thus, we summarized up the recent progress in the development of homogeneous and heterogeneous Cu-based WOCs for electrochemical catalysis. Furthermore, the evaluation of catalytic activity, stability, and mechanism of the catalysts are carefully concluded and highlighted. We believe that this review can help readers to review current progress in the field of Cu-based electrochemical WOCs and design more efficient and stable WOCs.
