Surface frustrated Lewis pairs in titanium nitride enable gas phase heterogeneous CO₂ photocatalysis.

ABSTRACT: Gas-phase heterogeneous catalytic CO₂ hydrogenation to commodity chemicals and fuels via surface frustrated Lewis pairs is a growing focus of scientific and technological interest. Traditional gas-phase heterogeneous surface frustrated Lewis pair catalysts primarily involve metal oxide-hydroxides (MOH•••M). An avenue to improve the process performance metrics lies in replacing the Lewis base MOH with a stronger alternative; an intriguing example being the amine MNH₂ in metal nitrides. This study establishes a proof-of-concept that an amine-type photoactive surface frustrated Lewis pair (MNH₂•••M) can be constructed in titanium nitride (TiN_xO_y) when integrated with a nanoscale platinum spillover co-catalyst. This surface frustrated Lewi
