New Horizon in stabilization of single atoms on metal-oxide supports for CO₂ reduction

Electrochemical CO₂ reduction is a promising route to convert CO₂ into the value added chemicals, and to control the increasing accumulation of CO₂ in the atmosphere. The CO₂ molecule is stable and chemically inert, so a highly efficient electrocatalyst is required for CO₂ reduction. The single atoms with metal oxide support is a new frontier in CO₂ reduction. The supported single atoms contain disperse isolated atoms with an appropriate support maximize the atom efficiency of metals for boosting the catalytic performance. In this review, we had discussed state-of-the-art research on the synthesis of single atoms supported on the metal oxide for boosting catalytic activity for CO₂ reduction and special emphasis is placed on the influence of single atoms supported on metal oxide on the CO₂ reduction. Furthermore, we had discussed the challenges, and opportunities for paving the development of single atoms with metal support and their application in electrocatalytic CO₂ reduction.
