Facet-engineered TiO₂ drives photocatalytic activity and stability of supported noble metal clusters during H₂ evolution.

ABSTRACT: Metal clusters supported on TiO₂ are widely used in many photocatalytic applications, including pollution control and production of solar fuels. Besides high photoactivity, stability during the photoreaction is another essential quality of high-performance photocatalysts, however systematic studies on this attribute are absent for metal clusters supported on TiO₂. Here we have studied, both experimentally and with first-principles simulation methods, the stability of Pt, Pd and Au clusters prepared by ball milling on nanoshaped anatase nanoparticles preferentially exposing {001} (plates) and {101} (bipyramids) facets during the photogeneration of hydrogen. It is found that Pt/TiO₂ exhibits superior stability than Pd/TiO₂ and Au/TiO₂, a
