Abstract The electrochemical CO 2 reduction reaction (CO2RR) to methanol offers an eco‐friendly approach reducing carbon emissions while producing versatile liquid fuels and feedstocks. However, achieving high selectivity for methanol, especially at current densities, remains challenging due competing reactions that favor methane hydrogen formation. Here, the tailored synthesis of Cu/Cu P O 7 ‐based hybrid catalysts is reported efficient selective production through discharge lithium‐ion batteries. catalyst exhibits a Faradaic efficiency exceeding 50% in both H‐cells gas‐diffusion electrode cells, one highest partial densities over 100 mA cm −2 . Experimental computational analyses reveal synergistic effect between Cu nanoparticles with predominant (111) surface nanoparticles, which enhances via HCOOH intermediate pathway. These findings provide insights into designing cost‐effective electrocatalysts production.

With the consequences of climate change becoming more urgent, there has never been a pressing need for technologies that can help to reduce carbon dioxide (CO2) emissions most polluting sectors, such as power generation, steel, cement, and chemical industry. This review summarizes state-of-the-art capture, instance, post-combustion, pre-combustion, oxy-fuel combustion, looping, direct air capture. Moreover, already established capture technologies, absorption, adsorption, membrane-based separation, emerging like calcium looping or cryogenic separation are presented. Beyond this also discusses how captured CO2 be securely stored (CCS) physically in deep saline aquifers depleted gas oil reservoirs, chemically via mineralization, used enhanced recovery. The concept utilizing (CCU) producing value-added products, including formic acid, methanol, urea, methane, towards circular economy will shortly discussed. Real-life applications, e.g., pilot-scale continuous methane (CH4) production from flue CO2, shown. Actual deployment crucial future explored real-life applications. aims provide compact view should considered when choosing store, convert informing researchers with efforts aimed at mitigating tackling crisis.

Thermo-catalytic CO2 hydrogenation to high-value oxygenates has been regarded as one of the most powerful strategies that can potentially alleviate excessive emissions. However, due high chemical stability and variability pathways, it is still challenging achieve highly active selective hydrogenation. Single atom catalysts (SACs) with ultrahigh metal utilization efficiency extraordinary electronic features have displayed growing importance for thermo-catalytic multiple developed improve performances. Here, we review breakthroughs in developing SACs efficient toward common (CO, HCOOH, CH3OH, CH3CH2OH) following order: first, an analysis reaction mechanisms thermodynamics challenges reactions; second, a summary SAs designed by dividing them into two categories single- dual-sites; third, discussion support effects focus on approaches regulating strong metal–support interaction (MSI). Summarily, current future perspectives develop higher-performance are presented. We expect this bring more design inspiration trigger innovation catalytic evolution materials eventually benefit achievement carbon-neutrality goal.

With the global shift in energy structure and advancement of "double carbon" strategy, methanol has gained attention as a clean low-carbon fuel engine sector. However, corrosion-wear coupling failure caused by acidic byproducts, such methanoic acid formaldehyde, generated during combustion severely limits durability engines.

ABSTRACT Direct catalytic hydrogenation of CO 2 into methanol and methyl formate (MF) under formic acid (FA) synthesis conditions is an exclusive property catalysts based on rhodium complexes. In their presence, the conversion occurs at room temperature without special addition alcohols to reaction medium. this work, transformation H FA, methanol, MF low‐temperature over chloride different composition compounds (RhCl (PPh 3 ) , HRh 4 (acac)Rh (CO) [RhCl ] modified with organophosphorus ligands (triphenylphosphine, triphenylphosphite, diphenylphosphonite, oligoarylene phenylphosphonites) has been investigated. The in situ FTIR method confirmed hydride nature active catalyst complex incorporation Rh‐H bond during temperature. dependence process selectivity donor–acceptor properties ligand, which affects electronic state, revealed. Whereas systems σ‐electron donor modifier (triphenylphosphine) synthesize FA 100% selectivity, π‐electron acceptor ligand ensure above 97%. Catalysts mixed characteristics (phosphites phosphonites) are favorable for production. phenylphosphonites provide 80%–87%, TON reaching 750–980.
