AI Article Synopsis
- A ternary heterostructured catalyst is developed using a combination of TiN nanotubes, TiO nanoparticulate layer, and InO(OH) nanoparticulate shell to enhance performance in the photocatalytic reverse water gas shift reaction.
- * The arrangement of these three components significantly affects the catalyst's effectiveness in CO photocatalysis, with the TiN nanotubes acting as a scaffold and providing photothermal energy.
- * The TiO layer contributes photogenerated electrons and holes that facilitate reactions on the InO(OH) nanoparticles, ultimately improving CO production rates.
Article Abstract
Herein is developed a ternary heterostructured catalyst, based on a periodic array of 1D TiN nanotubes, with a TiO nanoparticulate intermediate layer and a InO(OH) nanoparticulate shell for improved performance in the photocatalytic reverse water gas shift reaction. It is demonstrated that the ordering of the three components in the heterostructure sensitively determine its activity in CO photocatalysis. Specifically, TiN nanotubes not only provide a photothermal driving force for the photocatalytic reaction, owing to their strong optical absorption properties, but they also serve as a crucial scaffold for minimizing the required quantity of InO(OH) nanoparticles, leading to an enhanced CO production rate. Simultaneously, the TiO nanoparticle layer supplies photogenerated electrons and holes that are transferred to active sites on InO(OH) nanoparticles and participate in the reactions occurring at the catalyst surface.
