Sunlight‐powered reduction of CO2 to fuels and chemicals is a promising strategy to close the carbon loop and facilitate the energy transition. In this research, we demonstrate that Au nanoparticles supported on TiO2 are an efficient plasmonic catalyst for the sunlight‐powered reverse water‐gas shift (rWGS) reaction. A maximum CO production rate of 429 mmol ⋅ gAu−1 ⋅ h−1 with a selectivity of 98 % and an apparent quantum efficiency of 4.7 % were achieved using mildly concentrated sunlight (1.44 W ⋅ cm−2 equals 14.4 sun). The CO production rate showed an exponential increase with increasing light intensity, suggesting that the process is mainly promoted by a photothermal effect. Thermal reference experiments with the same catalysts promoted CH4 formation, dropping the CO selectivity to 70 %. Thus, mildly concentrated sunlight can efficiently and selectively enhance the promotion of the rWGS reaction without using external heating.

The economics of CO 2 utilization are discussed from a critical perspective, with a concise analysis of the state-of-the-art of economics in power-to-X (methanol, methane). The main elements of the analysis of the economics are commented to provide guidelines on how to interpret the techno-economic results in the area of CO 2 utilization. It remarks the need of a careful analysis of the specific context, and of the limits of the evaluation, in order to go beyond the just use of the results without a proper analysis of how the data support the conclusions, their limits and applicability. Case examples discussed in a more detail regard the CO 2 to methanol or methane conversion, from the perspective of highlighting possible issues or limits rather than to indicate which results are more valuable, which is out of the scope of this contribution.

“…21 On economic grounds, a recent technoeconomic analysis (TEA) of a direct CO 2 hydrogenation to MeOH process facilitated with solarthermal energy input showed a 26% improvement of the minimum selling price of the produced MeOH over other CO 2 -to-MeOH processes. 23 As an alternative strategy, direct use of nonfossil-based H 2surrogate feedstocks (such as alcohols) for the reduction of CO 2 to HCOOH and MeOH can be promising in this regard. Interestingly, transfer hydrogenation (TH), an old and established method commonly practiced in reducing various organic compounds, is found to be effective as an alternative catalytic protocol toward the reductive transformation of CO 2 .…”

Transfer Hydrogenation of CO₂ and CO₂ Derivatives using Alcohols as Hydride Sources: Boosting an H₂-Free Alternative Strategy

et al. 2022

Numerous strategies have been developed for the reduction of highly challenging CO 2 gas and its conversion into useful feedstock chemicals. Among all of the developed protocols, the traditional approach where H 2 gas is used as a reductant has been dominantly exploited. During the past decade, enormous efforts have been made in tackling the challenge by keeping sustainability as a major goal. As an alternative option, the adoption of a "transfer hydrogenation" strategy has received attention for the CO 2 reduction process. The utilization of biomass-derived alcohols as hydride donors promises to make the process viable and advantageous over the hydrogenation process. The survival of homogeneous transition-metal-based catalysts used in these processes under the harsh reaction conditions (elevated temperature and highly basic reaction medium) is a considerable challenge. Hence, the development of efficient and robust homogeneous catalysts for the CO 2 -transfer hydrogenation process is highly important. In this Perspective, we highlight the overall evolution of the transfer hydrogenation strategy for the reduction of CO 2 gas (and its derivatives) to hydrogenrich useful products achieved during the past decade. The role of tuning the ligand backbone to make the process kinetically more favorable is discussed in detail. The available reports in the field emphasized the advantages of using biomass-derived alcohols as hydride donors in place of nonrenewable H 2 gas. Potential benefits and opportunities of the CO 2 -transfer hydrogenation process over the traditional hydrogenation are critically presented to encourage further intense research in the field.
