Engineered disorder in CO₂ photocatalysis.

ABSTRACT: Light harvesting, separation of charge carriers, and surface reactions are three fundamental steps that are essential for an efficient photocatalyst. Here we show that these steps in the TiO₂ can be boosted simultaneously by disorder engineering. A solid-state reduction reaction between sodium and TiO₂ forms a core-shell c-TiO₂@a-TiO_2-x(OH)_y heterostructure, comprised of HO-Ti-[O]-Ti surface frustrated Lewis pairs (SFLPs) embedded in an amorphous shell surrounding a crystalline core, which enables a new genre of chemical reactivity. Specifically, these SFLPs heterolytically dissociate dihydrogen at room temperature to form charge-balancing protonated hydroxyl groups and hydrides at unsaturated titanium surface sites, which display high
