Abstract

A conceptual metallic/semiconducting TaB₂/Ta₂O ₅ core/shell heterostructure exhibits a substantial improvement in photocatalytic hydrogen evolution rate under both UV and visible light. TaB ₂ plays a dual role in boosting the photocatalytic activity by extending the light-absorption range via efficient interfacial electronic modification and by promoting the separation and transfer of photoexcited charge carriers by using metallic TaB₂ core as an electron collector.
