Titanium Nitride-Supported Platinum with Metal–Support Interaction for Boosting Photocatalytic H2 Evolution of Indium Sulfide
Source abstract
Abstract
Metal–support interaction strongly influences the catalytic properties of metal-based catalysts. Here, titanium nitride (TiN) nanospheres are shown to be an outstanding support, for tuning the electronic property of platinum (Pt) nanoparticles and adjusting the morphology of indium sulfide (In2S3) active components, forming flower-like core–shell nanostructures (TiN-Pt@In2S3). The strong metal–support interaction between Pt and TiN through the formation of Pt–Ti bonds favors the migration of charge carriers and leads to the easy reducibility of TiN-Pt, thus improving the photocatalytic atom efficiency of Pt. The TiN-Pt@In2S3 composite shows reduction of Pt loading by 70% compared to the optimal Pt-based system. In addition, the optimal TiN-Pt@In2S3 composite exhibits a H2 evolution rate 4 times that of a Pt reference. This increase outperforms all other supports reported thus far.
