报告摘要：Photocatalyst materials which are suitably stable often have large band gaps, and can only be activated by UV light. Our research has involved the synthesis and modification of novel inorganic nanostructured materials coupled with organic semiconductors in order to exploit their properties in visible light active photocatalytic systems.  In this talk I will present our recent progress in self-catalysed breakdown of titanate nanotubes by carbon nitride which can be viewed as a general method   for improving catalysis synthesis and design, whilst simultaneously reducing the complexity and energy footprint of active catalyst synthesis.  I will also present our preparation of a new phase with boron nitride by a novel mixed hydrothermal/solvothermal method at different temperatures and compared this to physical mixing. The composite prepared at 140 oC showed evidence of Ti-O-B bond formation and enhanced photocatalytic hydrogen production efficiency.
