- •
Au/Al2O3 shows excellent activity in CO2 hydrogenation to formates.
- •
Synergy between Au0 particles and oxide support is crucial for CO2 hydrogenation.
- •
Polar solvents are needed for high catalytic performance.
- •
Surface formate species are key intermediates in the catalytic reaction.
- •
Reaction mechanism over Au/Al2O3 resembles that of the homogeneous counterparts.
