(544ge) Synthesis and Applications of Heterogeneous Nitrides Nanophotocatalysts
AIChE Annual Meeting

In this talk, the first section will highlight the synthesis of GaN quantum dots (QDs) using a supercritical milli-tubular reactor working with hexane using two different process techniques (co-flow and pre-heater). We will detail the process employed and provide the advantageous features of the pre-heater approach and the reasons for opting it over co-flow technique. The GaN nanomaterial is active in the UV region, the subsequent work of this presentation will focus on the synthesis of GaxIn1-xN solid solution nanomaterial by introducing InN (active in the IR region) in GaN crystalline domain using double source precursors in a supercritical mixture. This solid solution rendered the materials active in the visible region. The talk will eventually provide insight in combining such materials with Titania (TiO2) for creating a nanocomposites resulting in a type II heterojunction and some demonstration of photocatalytic reactions performed with them.
