A Review on the Influence of Crystal Facets on the Product Selectivity of CORR over Cu Metal Catalysts.

The electrocatalytic carbon dioxide reduction reaction (ECRR) is promising in converting environmentally harmful CO into useful chemicals, but the large-scale application of this technology is seriously limited by its low efficiency and selectivity. Cu-based electrocatalysts displayed attractive ability in converting CO to multiple products, and the product selectivity can be manipulated through various approaches. Among them, exposing specific crystal facets through crystal facet engineering has been proven to be highly effective in obtaining specific products and has attracted numerous researchers.
