“…In advance, a recent report by da Silva et al [51] also verified the crucial role of water in driving selectivity to ethanol during CO 2 hydrogenation at atmospheric pressure over metallic Cu surfaces. By means of a thermocatalytic process, the authors achieved alcohol productivities in the same range as the electrocatalytic system, with ethanol selectivity achieving around 84 % at 190 °C.…”

Alcohol production from CO2 hydrogenation is a cutting‐edge process in sustainable chemistry that holds vast promise for addressing climate change by recycling and repurposing emissions. Many strategies have been proposed to improve the process efficiency. In‐situ generated, and trace amounts of water added to the feed stream have recently proved to be determinant to promote key reaction steps, increasing alcohol selectivity and yield. Here, we discuss the main findings that led to an atomic‐level understanding of water promotional effects in CO2 hydrogenation to alcohols. H2O and the products resultant from its dissociation (OH and O) can act in different ways, stabilizing intermediates and active sites or participating in the hydrogen transfer mechanisms during the reaction. Gaining insights into the mechanisms underlying water promotion offers a cost‐effective strategy for enhancing alcohol production efficiency.

Carbon dioxide (CO2) utilization technologies have emerged as a promising approach to address the direct and indirect consequences of climate change and the need for sustainable resource management. Those innovative technologies aim to capture and utilize CO2 by converting it into valuable products or directly using it as a chemical feedstock in various industries, thus, avoiding their release into the atmosphere. In this study, different CO2 utilization pathways including CO2 to chemicals and fuels, CO2 to building materials, CO2 to enhanced oil recovery (EOR), and CO2 to bio‐products are discussed in terms of their status ‐ economical, environmental, and technology readiness level performances. Moreover, various CO2 utilization pathways are comparatively analyzed considering their advantages and drawbacks, CO2 uptake potentials, and overall climate benefits. According to the comparison results, photocatalytic and electrochemical reduction of CO2 along with the bio‐fixation of CO2 are gaining more attention in the recent research and investigations from the energy intensity and environmental point of view, while EOR still dominant in terms of the scalability, maturity, and economical benefits. However, limitations of EOR related to the capacity, life cycle, and different geolocations, as well as the complexities of other mature approaches make room for emerging technologies to be more energy‐effective and environmentally friendly. Overall, most of the promising CO2 utilization techniques are either technologically immature or limited in scale to deploy globally. One of the main barriers to reusing CO2 is associated with the high cost of CO2‐based production and the low value of the CO2 market.This article is protected by copyright. All rights reserved.
