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.
