Unlocking synergy between multi-valence rhodium species for promoted methanol photoreforming.

ABSTRACT: Solar-powered photocatalytic methanol dehydrogenation to produce hydrogen (H₂) and formaldehyde provides a promising approach for storable H₂ fuel without carbon emissions. However, the different properties of C-H and O-H bonds in methanol molecules make it challenging to cleave both bonds effectively on a single catalytic active site during the methanol dehydrogenation process. This work proposes a strategy that constructs multi-valence metal species in the co-catalyst to address this challenge. In the case study of multi-valence rhodium species (Rh⁰ and Rh³⁺) on titanium dioxide (RhO _x /TiO₂) photocatalysts, an apparent turnover frequency (TOF, the H₂ evolution rate as a function of the co-catalyst amount
