Heterostructured photocatalysts were prepared to have nanostructured (ns) TiO2 shells surrounding microcrystalline (mc) cores of (Ba,Sr)TiO3. The as‐prepared heterostructures were annealed between 400°C and 600°C to improve crystallinity and core‐shell interfacial bonding. X‐ray diffraction, electron microscopy, and gas adsorption measurements demonstrated that 50 nm thick shells composed of nanocrystalline and nanoporous TiO2 surrounded mc‐cores such that the heterostructured particles had surface areas of 50–100 m2/g. The mc‐(Ba,Sr)TiO3/nsTiO2 core‐shell photocatalysts annealed at 600°C had slightly reduced surface areas, but had the highest rates of photochemical hydrogen production from water/methanol solutions, rates much greater than those for nsTiO2 or mc‐(Ba,Sr)TiO3 alone. Such heterostructured powders represent a new strategy for the design of efficient photocatalysts and the use of nanostructured catalytic coatings.
