What is Theoretical Calculation of Hydrogen Generation and Delivery via Photocatalytic Water Splitting in Boron–Carbon–Nitride Nanotube/Metal Cluster Hybrid about?
Solar-driven water splitting is an appealing strategy to produce hydrogen energy. However, the non-negligible chance of reverse reactions due to a mixture of hydrogen molecules (H) with oxygen species poses challenges for safe H collection and delivery, which hinders its applications. Using first-principles simulations, we propose a hybrid structure design where metal clusters of TM (TM = Au/Pt) are encapsulated in boron-carbon-nitride nanotube (BCNNT) decorated with CuN group. It can readily absorb ultraviolet-visible solar light to generate charge carriers. The energetic electrons and holes would be separately delivered to the reduction site of TM and the oxidation site of the BCNNT layer. Then, protons generated by water dissociation at the BCNNT layer will penetrate through BCNNT and consequently meet electrons at the TM site to be reduced into H. As a selective sieve, BCNNT prevents oxygen species from going inside and H from crossing out so that H can be completely isolated. Further, the sufficient space of the tubular cavity endows the transportation feasibility of the produced H along the nanotube for collection. This proposed design combines photocatalytic hydrogen product
