Abstract: 
Controlled heterojunction design was combined with diameter-tailored electrospinning to prepare mesostructured photocatalysts, leading to strongly enhanced photocatalytic water splitting rates. The (111)-layered perovskite Ba5Ta4O15 in heterojunction with Ba3Ta5O15 was for the first time prepared as nanofibers by means of electrospinning, including variation of the fiber diameter. The result is a tailored mesostructured heterojunction leading to hydrogen evolution rates from water/methanol mixtures of up to 4.4 mmol h(-1) without cocatalyst, and remarkable water splitting activity after Rh-Cr2O3 decoration with hydrogen production rates up to one mmol h(-1). Our studies also confirm the photocurrent doubling effect of sacrificial alcohols exhibiting alpha-H atoms with this heterojunction, in contrast to tert-butanol.
