Summary: In this study, anatase TiO2{101}-supported Pd and PdAg catalysts were used for CO2 hydrogenation into formic acid. By finely tuning the electronic properties of the supported Pd species, it was found that the Pd0.2Ag0.04/TiO2 catalyst with a Pd:Ag mole ratio of 5 exhibited a very high formic acid yield.

Summary: Progress has been made in the application of transfer hydrogenation strategy for CO2 reduction in the past decade. The use of biomass-derived alcohols as hydride donors shows promise in replacing traditional hydrogenation process. However, finding efficient and stable homogeneous catalysts under harsh reaction conditions remains a challenge.

Summary: The effects of Pd catalysts supported on different exposed facets of anatase TiO2 nanocrystals on the hydrogenation of CO2 to formate were investigated. It was found that the 2%Pd/TiO2 {1 0 0} catalyst exhibited high activity and stability, with a high turnover frequency and stability. This can be attributed to the higher density of moderate basic sites and higher oxygen vacancy concentration on the TiO2 {1 0 0} surface, which promote the activation of CO2 and H-2, and the formation of stable Pd particles.

Summary: By using the La-MOF JMS-5 with a bipyridyl dicarboxylate linker and cyclometalation with platinum-group metals, catalytic hydrogenation of carbon dioxide to formate was achieved with high TON values for Ir-(III) and Rh-(III) without nanoparticle formation. The MOF showed an unusual rod topology and was fully characterized. The conversion of carbon dioxide to formate is important for hydrogen storage and accessing olefins.

Summary: The newly designed solid micellar Ru single-atom catalyst allows for efficient and stable water-free CO2 hydrogenation to formic acid, producing concentrated formate solutions. The incorporation of Ru(III) single sites into the MCM-41 walls creates a solid micelle structure, while the presence of CTA(+) surfactant in the pores of MCM-41 stabilizes the Ru sites and prevents catalyst deactivation. DFT modelling indicates that the reaction proceeds via heterolytic hydrogen splitting, forming a Ru-H species and subsequent hydride transfer to CO2.

Summary: Reducing carbon dioxide to valuable chemicals and fuels via thermocatalysis or electrocatalysis is a sustainable way to address carbon abatement and climate change. Thermocatalysis is scalable but limited by kinetics and thermodynamics, while electrocatalysis has advantages such as lower temperature and pressure, but requires more effective and stable catalysts. This review summarizes the progress and compares catalysts and reaction mechanisms in CO2 conversion via thermocatalysis and electrocatalysis.
