Constructing a Metallic/Semiconducting TaB2/Ta2O5 Core/Shell Heterostructure for Photocatalytic Hydrogen Evolution. Issue 12 (25th April 2014) - Yang, Yongqiang
Abstract A conceptual metallic/semiconducting TaB2/Ta2O5 core/shell heterostructure exhibits a substantial improvement in photocatalytic hydrogen evolution rate under both UV and visible light. TaB2 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.
