“…More recently, advancing experimental and theoretical methods gave a better understanding of the catalyst structure and active sites, considerably improving the productivity of higher alcohols. [45] Many reviews [46][47][48] have already covered the impact of catalyst morphology on the production of higher alcohols, a topic that will not be discussed here. On the other hand, only a few papers touch on the impact of water in higher alcohol synthesis, even though water is massively produced as a co-product of C 2 + OH formation, and its presence cannot be avoided in the catalytic process.…”

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.

“…Energy holds a prominent role in modern societies, and the increase in world population and living standards will inevitably lead to further rises in the energy demand [1]. However, even though tremendous effort has been put toward developing renewable energy sources (RESs), fossil fuels are still responsible for nearly 80% of global energy consumption, with the remaining 20% also including nuclear and large-scale hydropower [2,3]. Because of the energy model followed for the past 200 years, the concentration of carbon dioxide (CO 2 ) has been steadily rising (it stood at around 419 ppm by June 2021 [4]), driving the continual increase in global surface and ocean temperatures [5,6].…”

Given that the attempts to head toward a hydrogen economy are gathering pace, the dry reforming of methane (DRM) to produce hydrogen-rich syngas is a reaction that is worthy of investigation. Nickel-based catalysts have been extensively examined as a cost-effective solution for DRM, though they suffer from fast deactivation caused by coke accumulation. However, a number of published studies report high catalytic performance in terms of both activity and stability for La–Ni-based perovskite-derived catalysts used in DRM in comparison to other corresponding materials. In the work presented herein, a thorough analysis regarding the application of La–Ni-based perovskite catalysts for DRM is carried out. LaNiO3 is known for its anti-coking ability owing to the strong interaction between CO2 and La2O3. A further modification to improve the catalytic performance can be achieved by the partial or complete substitution of A or/and B sites of the perovskite catalysts. The latest developments with respect to this topic are also discussed in this manuscript. Even though the low surface area of perovskite catalysts has always been an obstacle for their commercialization, new supported and porous perovskite materials have recently emerged to address, at least partly, the challenge. Finally, conclusions and future outlooks for developing novel perovskite catalysts that may potentially pioneer new technology are included.

“…The removal of CO 2 from flue gases has gained great significance during the attempt to decarbonize our economy, since the remaining emitters and hard-to-decarbonize sectors face increasing demands to cut down on their CO 2 output via the integration of carbon capture procedures [1][2][3]. CO 2 adsorption from solid materials is regarded as an attractive option due to potential energy savings, with solids such as zeolites, activated carbons, and calcium oxides commonly employed for this purpose (including commercially available solid materials) [4].…”

The present work studies the adsorption of CO2 using a zeolitic industrial molecular sieve (IMS) with a high surface area. The effect of the CO2 feed concentration and the adsorption temperature in conjunction with multiple adsorption–desorption cycles was experimentally investigated. To assess the validity of the experimental results, theoretical calculations based on well-established equations were employed and the values of equilibrium, kinetic, and thermodynamic parameters are presented. Three additional column kinetic models were applied to the data obtained experimentally, in order to predict the breakthrough curves and thus facilitate process design. Results showed a negative correlation between temperature and adsorption capacity, indicating that physical adsorption takes place. Theoretical calculations revealed that the Langmuir isotherm, the Bangham kinetic model (i.e., pore diffusion is the rate-determining step), and the Thomas and Yoon–Nelson models were suitable to describe the CO2 adsorption process by the IMS. The IMS adsorbent material maintained its high CO2 adsorption capacity (>200 mg g−1) after multiple adsorption–desorption cycles, showing excellent regenerability and requiring only a mild desorption treatment (200 °C for 15 min) for regeneration.
