Boosting the reduction of CO2 and dimethylamine for C–N bonding to synthesize DMF via modulating the electronic structures of indium single atoms

The indium single atom of InN 3 affects the electronic properties of adsorption of CO 2 and HN(CH 3 ) 2 . This resulted in hydrogen transfer from HN(CH 3 ) 2 to CO 2 , generating the intermediate species of *N(CH 3 ) 2 and *COOH that are conducive to C–N coupling.
