Unraveling the atomic structure and dissociation of interfacial water on anatase TiO (101) under ambient conditions with solid-state NMR spectroscopy.

Anatase TiO is a widely used component in photo- and electro-catalysts for water splitting, and the (101) facet of anatase TiO is the most commonly exposed surface. A detailed understanding of the behavior of HO on this surface could provide fundamental insights into the catalytic mechanism. This, however, is challenging due to the complexity of the interfacial environments, the high mobility of interfacial HO, and the interference from outer-layer HO.

Efficient and selective photocatalytic CH conversion to CHOH with O by controlling overoxidation on TiO.

The conversion of photocatalytic methane into methanol in high yield with selectivity remains a huge challenge due to unavoidable overoxidation. Here, the photocatalytic oxidation of CH into CHOH by O is carried out on Ag-decorated facet-dominated TiO. The {001}-dominated TiO shows a durable CHOH yield of 4.
