The electrocatalytic reduction of CO2 (CO2RR) to high market value HCOOH is highly attractive and challenging in chemistry. p-Block metals (Sn, Bi, In, Pb, Sb) are promising candidates trigger formate due their specific stabilization the HCOO* intermediate, while overpotential low selectivity have now limited its practical application. Herein, we rationally designed a series p-block single atom anchored MoS2 monolayer catalysts for efficient electroreduction by DFT methods. systematic thermal evaluation demonstrates that Sn, Sb, Tl, Bi atoms could be atomically dispersed on 1T-MoS2 with stability potentially synthesized experiment. We reveal catalytic CO2RR activity metal correlated degree charge transfer between substrate, higher distribution induced stronger interaction HCOO intermediate. Among six concept SACs, Sb- Bi-atom-supported identified as most produce HCOOH, offering excellent energy efficiency against hydrogen evolution reaction.

CO2 electroreduction has emerged as a promising strategy for reducing emissions while simultaneously generating valuable products, particularly formic acid/formate. To further enhance the sustainability of this process, traditional oxygen evolution reaction at anode can be replaced by more interesting like glycerol oxidation to high value-added in covalorization approach. In study, effect presence bismuth (Bi) atom supplier (Bi2O3 particles) anolyte solution during electrooxidation process on platinum (Pt) electrodes coupled with formate is investigated first time, operating continuous mode single pass through reactor. The results reveal that cathode, significant HCOO– production, Faradaic efficiencies reaching 93%, and modest energy consumption 208 kW h·kmol–1 were obtained using Bi gas diffusion electrodes. On other hand, anode, Bi2O3 particles leads alteration distribution high-value-added products obtained. For instance, demonstrates remarkable dihydroxyacetone (DHA) production 283 μmol·m–2·s–1, surpassing nonmodified Pt performance system offers pathway simultaneous coproduction from both glycerol.

Previous research in CO2 electroreduction primarily focused on cathodic electrocatalysts and electrode configurations using pure CO2. Few studies explored the impact of residence time N2/O2 compounds, crucial for practical industrial implementation. In this study, effect influence N2 O2 compounds to formate are investigated, employing Bi carbon-supported nanoparticles form Gas Diffusion Electrodes within an electrochemical flow reactor with a single pass reactants. The results highlight critical role electroconversion process. On one hand, evaluation holds paramount significance potential establishment large-scale recycling plant, as it has significantly both capital operational costs integrated electrolyzer-separator system. Optimal obtained range times between 1.8 2.9 seconds, corresponding rates 150 250 mL·min−1, respectively. other study resulted promising Faradaic Efficiency 75.0%, similar values achieved at concentrations 75 – 100 vol%. These particularly noteworthy they demonstrate that achieving capture efficiency 100% is not necessary, thereby reducing associated process and, consequently, overall cost integrating utilization processes plant.
