We propose a partially-oxidised bimetallic Mo-Pt subnanoparticle (Mo4Pt8Ox) that facilitates thermally-driven CO2 hydrogenation to CO at room temperature and atmospheric pressure. A mechanistic study elucidated the entire catalytic cycle of the reaction, from CO2 activation to catalyst reactivation. DFT calculations showed that alloying with Mo decreases the activation barrier by weakening CO adsorption, presenting a potential pathway for low-energy CO2 conversion.
We present a partially-oxidised bimetallic Mo-Pt subnanoparticle (Mo4Pt8Ox) enabling thermally-driven CO2 hydrogenation to CO at room temperature and atmospheric pressure. A mechanistic study explained the full catalytic cycle of the reaction from CO2 activation to catalyst reactivation. DFT calculations revealed that alloying with Mo lowers the activation barrier by weakening the CO adsorption. This finding could be a first step for low-energy CO2 conversion.
