Efficient full-spectrum driven ammonia synthesis over heterostructured TiO2 nanosheet arrays

Abstract

Here, we report that efficient photocatalytic ammonia synthesis was realized across the entire solar spectrum by using Ru modified anatase/TiO₂(B) heterostructured nanosheet arrays. The superior NH₃ production rates of 2004 μg h⁻¹ g⁻¹ and 521 μg h⁻¹ g⁻¹ were achieved under visible light (400 nm) and near-infrared-light (1550 nm) irradiation, respectively.
