Porous NiTiO3/TiO2 nanostructures for photocatatalytic hydrogen evolution

Kevin Sivula, Nestor Guijarro Carratala, Yongpeng Liu, Yu Zhang, Ting Zhang, Yong Zuo

We present a strategy to produce porous NiTiO3/TiO2 nanostructures with excellent photocatalytic activity toward hydrogen generation. In a first step, nickel-doped TiO2 needle bundles were synthesized by a hydrothermal procedure. Through the sintering in a ...
