摘要：The increasing need for new materials capable of solar fuel production is central to the development of green energy economy. Utilizing solar energy for hydrogen generation is a great challenge due to inefficient light utilization and fast charge recombination. In this work, disorder-engineered black H-TiO2@BN with Ti-B chemically bonded interfaces was synthesized by employing BN nanosheets as the photocatalyst support. The hybridization of TiO2 with BN and hydrogenated thermal treatment work synergistically to enable the photo catalytic H-2 production without noble metal cocatalysts. The hybrid photocatalyst markedly enhanced light absorption, significantly retarded charge pair recombination, facilitated interfacial electron transfer, and lowered interfacial charge transfer resistance. As a result, the photocatalytic H-2 production activity of H-TiO2@BN that consisted of earth-abundant elements only was comparable to that of Pt-TiO2. The present hybrid engineering for the efficient charge separation and transfer via the formation of the interfacial chemical bonds should provide a useful methodology for designing the new types of hybrid photocatalysts.
