A conceptual urchin‐like metallic/semiconducting TaB 2 /Ta 2 O 5 core/shell heterostructure exhibits a substantial improvement in the photocatalytic hydrogen evolution rate under both UV‐visible and visible light. As reported by Gang Liu and co‐workers in article number 1400057, TaB 2 plays a dual role in boosting the photocatalytic activity by extending the light absorption range and promoting the separation/transfer of photoexcited charge carriers.
