Flux-mediated doping of SrTiO3 photocatalysts for efficient overall water splitting

Boosting the Efficiency of Suspended Photocatalysts for Overall Water Splitting.

Water Splitting I is a significant task to cover the residential energy demand of a society (approximately 20% of the total) with solar energy, but it is a much greater challenge to cover all of it, including the demands of industry, commerce, and transportation. The 20% goal may be achievable through photovoltaic-powered households and appliances, but the 100% goal will require extensive facil...

Nanoscale strontium titanate photocatalysts for overall water splitting.

SrTiO(3) (STO) is a large band gap (3.2 eV) semiconductor that catalyzes the overall water splitting reaction under UV light irradiation in the presence of a NiO cocatalyst. As we show here, the reactivity persists in nanoscale particles of the material, although the process is less effective at the nanoscale. To reach these conclusions, Bulk STO, 30 ± 5 nm STO, and 6.5 ± 1 nm STO were synthesi...

Transient Behavior of Ni@NiOx Functionalized SrTiO3 in Overall Water Splitting

Transients in the composition of Ni@NiO x core-shell co-catalysts deposited on SrTiO3 are discussed on the basis of state-of-the-art continuous analysis of photocatalytic water splitting, and post-XPS and TEM analyses. The formation of excessive hydrogen (H2:O2 ≫ 2) in the initial stages of illumination demonstrates oxidation of Ni(OH)2 to NiOOH (nickel oxyhydroxide), with the latter catalyzing...
