Efficient electrocatalytic reduction of CO2 on CuxO decorated graphene oxides: an insight into the role of multivalent Cu in selectivity and durability

Copper oxides have been used as efficient electrocatalysts for electrocatalytic reduction of carbon dioxide (CO2). However, understanding the catalytic mechanism of copper oxides electrocatalysts based on identifying their active species is difficult due to the presence of multivalent Cu, such as Cu(0), Cu(I) and Cu(II) species, during the reaction. Also, developing copper oxides electrocatalysts with high selectivity and long durability for...
