Electrochemical CO2 reduction reaction (CO2RR) has attracted much attention in the last decade, owing to its unique advantages such as operation at ambient conditions, coupling with renewable electricity, and producing a wide range of products and commodities. The majority of CO2RR studies are focused on pure CO2 as feed, while in real CO2 waste streams, such as flue gas or biogas, CO2 concentration does not exceed 40%. Therefore, the economic feasibility of CO2RR and its carbon footprint are greatly limited by the CO2 purification steps before electrolysis ($70–100 per ton of CO2 for CO2/N2 separation). In recent years, studies have exhibited the importance of this matter by integrating CO2 capture and electroreduction in a single unit. Mostly, CO2 capture solutions as electrolytes have been under attention, and promising results have been achieved to significantly improve the overall economy of CO2RR. The focus on CO2 capture‐electroreduction integration can go beyond the solution/electrolyte‐based CO2 capture (e.g., amine solutions and ionic liquids) and other processes such as solid adsorption and membrane‐based processes, as more efficient options, can be potentially integrated with CO2 electroreduction in the gas‐diffusion electrode design. This article aims to review the recent efforts in integrating capture and electroreduction of CO2 and provides new perspectives in material selection and electrode design for membrane‐ and adsorption‐based CO2 capture‐reduction integration, in addition to the analysis of the economic feasibility of this integration.

“…In addition, zeolite-confined Fe-based catalysts have also garnered significant interest for CO 2 hydrogenation, owing to their exceptional efficiency, versatile framework, and customizable composition. The role of zeolite properties, including topology, the nature, density, and strength of acid sites, and metal–zeolite interactions, has been comprehensively reviewed in the literature for its influence on catalytic activity and product selectivity [ 30 , 31 , 32 ].…”

Catalytic hydrogenation presents a promising approach for converting CO2 into valuable chemicals and fuels, crucial for climate change mitigation. Iron-based catalysts have emerged as key contributors, particularly in driving the reverse water–gas shift and Fischer–Tropsch synthesis reactions. Recent research has focused on enhancing the efficiency and selectivity of these catalysts by incorporating alkali metal promoters or transition metal dopants, enabling precise adjustments to their composition and properties. This review synthesizes recent theoretical advancements in CO2 hydrogenation with iron-based catalysts, employing density functional theory and microkinetic modeling. By elucidating the underlying mechanisms involving metallic iron, iron oxides, and iron carbides, we address current challenges and provide insights for future sustainable CO2 hydrogenation developments.

“…CO 2 mitigation in the atmosphere is investigated via two strategies: capture and utilization. CO 2 can be captured by numerous high surface porous materials [5] or converted into useful compounds and fuels, such as dimethyl carbonate [6], or via dry reforming [7,8], CO 2 hydrogenation to methanol [9], and CO 2 methanation [10]. Dry reforming reactions require high operating temperatures, as CH 4 and CO 2 are thermally stable compounds, in addition to the fast coke formation, as carbon originates from two sources (CH 4 and CO 2 ), which poisons the catalyst and blocks the reactors [11][12][13].…”

Due to ever-increasing global warming, the scientific community is concerned with finding immediate solutions to reduce or utilize carbon dioxide (CO2) and convert it in useful compounds. In this context, the reductive process of CO2 methanation has been well-investigated and found to be attractive due to its simplicity. However, it requires the development of highly active catalysts. In this mini-review, the focus is on biochar-immobilized nanocatalysts for CO2 methanation. We summarize the recent literature on the topic, reporting strategies for designing biochar with immobilized nanocatalysts and their performance in CO2 methanation. We review the thermochemical transformation of biomass into biochar and its decoration with CO2 methanation catalysts. We also tackle direct methods of obtaining biochar nanocatalysts, in one pot, from nanocatalyst precursor-impregnated biomass. We review the effect of the initial biomass nature, as well as the conditions that permit tuning the performances of the composite catalysts. Finally, we discuss the CO2 methanation performance and how it could be improved, keeping in mind low operation costs and sustainability.
