Electrochemical CO2 reduction reaction (CO2RR) provides a promising approach to curbing harmful emissions contributing to global warming. However, several challenges hinder the commercialization of this technology, including high overpotentials, electrode instability, and low Faradic efficiencies of desirable products. Several materials have been developed to overcome these challenges. This mini-review discusses the recent performance of various cobalt (Co) electrocatalysts, including Co-single atom, Co-multi metals, Co-complexes, Co-based metal–organic frameworks (MOFs), Co-based covalent organic frameworks (COFs), Co-nitrides, and Co-oxides. These materials are reviewed with respect to their stability of facilitating CO2 conversion to valuable products, and a summary of the current literature is highlighted, along with future perspectives for the development of efficient CO2RR.

Zeolite and non-zeolite catalysts for CO 2 valorization into hydrocarbon fuels. • Excessive amount of CO 2 emission in the atmosphere causes global warming. • Chemical methods for CO 2 conversion are highlighted as the best options. • Catalysts based on zeolites are currently being explored for hydrocarbons production. • Fe-based non-zeolitic catalysts are the most widely used for hydrocarbons production. • Zeolitic-imidazole frameworks (ZIFs), covalent-organic frameworks (COFs), and metal-organic frameworks (MOFs) are probably selective catalysts for CO 2 conversion to hydrocarbons. Meeting the ever-increasing global energy demands is one of the serious challenges of the 21st century. It is estimated that about 80% of the global energy demand is supplied by the fossil fuels which in turn promote global warming upon their consumption and cause harmful effects on the environment. One of the major causes of global warming is the excessive accumulation of CO 2 into the atmosphere. An important way for mitigating the excessive amount of CO 2 is to transform it into the hydrocarbons (HC) fuels. In this article, we have addressed various issues aroused by CO 2 emission and their possible solutions. Various routes for CO 2 upgrading into HC fuels are comprehensively elaborated. Furthermore, we have focused on the heterogeneous catalysis for CO 2 conversion to value-added HC fuels by utilizing zeolite and non-zeolite based catalysts. The role of noble metals-based catalysts (such as Rh and Ru) and the transition metals containing Ni-species supported on zeolites in CO 2 conversion to (HC) fuels is discussed. In addition, the role of Fe- and MOFs based non-zeolite based catalysts for the generation of HC fuels via the CO 2 hydrogenation is also discussed. Finally, this review article highlights the prospective areas for research and technology advances. In brief, this review is focused on zeolite and non-zeolite based catalytic route for CO 2 to HC fuel and reflects its importance for both the industries and academia. [ABSTRACT FROM AUTHOR]
