“…Methanol and formate are considered as valuable substrates for sustainable biotechnology-based production of chemicals as well as food and feed proteins. Both methanol and formate can be produced electrochemically from CO 2 2,3 . Co-assimilation of CO 2 with methanol or formate would even allow for direct carbon capturing to reduce greenhouse gas emissions.…”

The current climate change is mainly driven by excessive anthropogenic CO2 emissions. As industrial bioprocesses depend mostly on food competing organic feedstocks or fossil raw materials, we regard CO2 co-assimilation or the use of CO2-derived methanol or formate as carbon source as pathbreaking contribution to the solution of this global problem. The number of industrially relevant microorganisms that can use these two carbon sources is limited, and even less can concurrently co-assimilate CO2. Hence, we searched for alternative native methanol and native formate assimilation pathways which co-assimilate CO2 in the industrially relevant methylotrophic yeast Komagataella phaffii (Pichia pastoris). Using 13C-tracer-based metabolomics techniques and metabolic engineering approaches we discovered and confirmed a natively active pathway that can perform all three assimilations: the oxygen tolerant reductive glycine pathway. This finding paves the way towards metabolic engineering of formate and CO2 utilisation for the production of proteins, biomass or chemicals in yeast.

“…[25] To rule out a change in surface species coverages or surface changes as the main cause for the faster initial decomposition of formates compared to carbonyls on Co/SiO 2 , a steady-state isotopic transient kinetic analysis (SSITKA) FTIR experiment was performed. In SSITKA, a switch between chemically identical feeds containing 12 CO 2 and 13 CO 2 isotopologues is made. Thus, in SSITKA-FTIR all spectra are acquired under steady-state.…”

“…On the contrary, the reaction at a low partial pressure of CO 2 remains largely underexplored, especially for heterogeneous systems (Figure S2) [10] . This aspect is increasingly important for the direct valorization of atmospheric CO 2 , with no separate energy‐intensive separation and purification steps, which can offer environmental and economic benefits [11, 12] . Kuramoto and co‐workers, for example, demonstrated the feasibility of such a process in a cycled fixed‐bed reactor using a hybrid Ni/Na‐γ‐Al 2 O 3 system, fulfilling both the roles of CO 2 adsorbent and methanation catalyst [13] …”

Ceria‐Supported Cobalt Catalyst for Low‐Temperature Methanation at Low Partial Pressures of CO₂

The direct catalytic conversion of atmospheric CO 2 to valuable chemicals is a promising solution to avert negative consequences of rising CO 2 concentration. However, heterogeneous catalysts efficient at low partial pressures of CO 2 still need to be developed. Here, we explore Co/CeO 2 as a catalyst for the methanation of diluted CO 2 streams. This material displays an excellent performance at reaction temperatures as low as 175 °C and CO 2 partial pressures as low as 0.4 mbar (the atmospheric CO 2 concentration). To gain mechanistic understanding of this unusual activity, we employed in situ X-ray photoelectron spectroscopy and operando infrared spectroscopy. The higher surface concentration and reactivity of formates and carbonyls -key reaction intermediates-explain the superior activity of Co/CeO 2 as compared to a conventional Co/ SiO 2 catalyst. This work emphasizes the catalytic role of the cobalt-ceria interface and will aid in developing more efficient CO 2 hydrogenation catalysts.

Electrochemical carbon dioxide (CO2) conversion technologies have become new favorites for addressing environmental and energy issues, especially with direct electrocatalytic reduction of CO2 (ECO2RR) and alkali metal‐CO2 (M–CO2) batteries as representatives. They are poised to create new economic drivers while also paving the way for a cleaner and more sustainable future for humanity. Although still far from practical application, ECO2RR has been intensively investigated over the last few years, with some achievements. In stark contrast, M–CO2 batteries, especially aqueous and hybrid M–CO2 batteries, offer the potential to combine energy storage and ECO2RR into an integrated system, but their research is still in the early stages. This article gives an insightful review, comparison, and analysis of recent advances in ECO2RR and M–CO2 batteries, illustrating their similarities and differences, aiming to advance their development and innovation. Considering the crucial role of well‐designed functional materials in facilitating ECO2RR and M–CO2 batteries, special attention is paid to the development of rational design strategies for functional materials and components, such as electrodes/catalysts, electrolytes, and membranes/separators, at the industrial level and their impact on CO2 conversion. Moreover, future perspectives and research suggestions for ECO2RR and M–CO2 batteries are presented to facilitate practical applications.
