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.

Hydroxylamine, as an important reducing agent, disinfectant, foaming and biocide, plays a role in both human life industrial production. However, its synthesis is confronted with challenges, such high pollution large consumption. Here, we propose coordination tailoring strategy to design 47 graphene-supported single iron atom catalysts (SACs), namely, Fe@CxZy (Z = B, N, O, P, S), for the reduction of nitric oxide hydroxylamine. Using density functional theory calculations, demonstrated great impact environment on stability, catalytic selectivity, activity Fe site. We identified that experimentally available Fe@N4 possesses ultralow theoretical limiting potential −0.32 V compared other catalysts. A comprehensive investigation electronic properties elucidates underlying active origin reaction mechanism hydroxylamine Fe@N4. These results not only explain synthesized SACs NH2OH production but also offer guidance further optimizing high-performance

Designing heterogeneous catalysts with dual-functional sites for hydrogenation reactions holds significant potential improving activity and selectivity. We present that incorporate two distinct metal onto a MgO support, serving as adsorption reactant H2, respectively. From screening 16 candidates using density functional theory calculations, we identified Pt1Al1/MgO promising catalyst nitroaromatic hydrogenation. The Al–Mg moiety adsorbs 3-nitrostyrene via its nitro group, while the neighboring Pt–O facilitates H2 dissociation through transient frustrated Lewis pairs. synergistic effect of Al–O–Pt enhances reaction activity, driven by appropriate adsorption/desorption *H at Pt site low diffusion barrier. This study offers valuable insights into design pair is pivotal development dual-sites reactions.
