Abstract

Photocatalytic H ₂generation by water splitting is a promising alternative for producing renewable fuels. This work synthesized a new type of Ta ₂O ₅/SrZrO ₃heterostructure with Ru and Cu (RuO ₂/Cu _xO/Ta ₂O ₅/SrZrO ₃) using solid-state chemistry methods to achieve a high H ₂production of 5164 μmol g ^-1h ^-1under simulated solar light, 39 times higher than that produced using SrZrO ₃. The heterostructure performance is compared with other Ta ₂O ₅/SrZrO ₃heterostructure compositions loaded with RuO ₂, Cu _xO, or Pt. Cu _xO is used to showcase the usage of less costly cocatalysts to produce H ₂. The photocatalytic activity toward H ₂by the RuO ₂/Cu _xO/Ta ₂O ₅/SrZrO ₃heterostructure remains the highest, followed by RuO ₂/Ta ₂O ₅/SrZrO ₃> Cu _xO/Ta ₂O ₅/SrZrO ₃> Pt/Ta ₂O ₅/SrZrO ₃> Ta ₂O ₅/SrZrO ₃> SrZrO ₃. Band gap tunability and high optical absorbance in the visible region are more prominent for the heterostructures containing cocatalysts (RuO ₂or Cu _xO) and are even higher for the binary catalyst (RuO ₂/Cu _xO). The presence of the binary catalyst is observed to impact the charge carrier transport in Ta ₂O ₅/SrZrO ₃, improving the solar to hydrogen conversion efficiency. The results represent a valuable contribution to the design of SrZrO ₃-based heterostructures for photocatalytic H ₂production by solar water splitting.
