The unique capacity of localized surface plasmon resonance (LSPR) offers a new opportunity to overcome the limited efficiency semiconductor photocatalyst. Here we unravel that LSPR, which usually occurs in noble metal nanoparticles, can be realized by hydrogen doping noble-metal-free using TiO2 as model Moreover, its LSPR is located infrared region, supplements whose generally visible making it possible extend light response photocatalyst region. near field enhancement shown comparable with noble-metal indicating highly enhanced absorption rate expected. present work provide key guideline for creation efficient plasmonic photocatalysts and have much wider impact bioimaging spectroscopy where essential.
