Greenhouse effect and energy crisis require the recycling use of carbon dioxide (CO2) in atmosphere. The electrocatalytic reduction of CO2 transformed to value-added chemicals with sustainable energy derived electric energy provides a feasible way to address these energy and environment problems; however, developing the electrocatalysts with highly active, selective and durability is still a significant challenge for electrocatalytic CO2 reduction reaction (CO2RR). The nanostructured electrocatalysts have been extensively researched as promising catalysts to speed up CO2 conversion. Here, we summarized the recent advances in different-dimension nanostructured electrocatalysts for CO2RR, tried to give a picture on how do different dimension catalysts work, and discussed the challenges and perspectives for achieving high CO2RR electrocatalysts.
