Abstract

Less

Photocatalytic nitrogen reduction to produce ammonia under ambient conditions is a promising green route. In this study, we demonstrate that one-dimensional (1D) TiO₂ nanobelts, prepared via a facile hydrothermal method, can convert gaseous dinitrogen to ammonia in pure water under light irradiation. The photocatalytic ammonia production performance of TiO₂ nanobelts can be further enhanced through acid corrosion treatment, which generates secondary nanostructures. These surface nanostructures serve as potential catalytically active sites for nitrogen adsorption and reduction. Both photoelectrochemical measurements and photoluminescence spectra confirm that the optimized TiO₂ nanobelts exhibit improved charge separation. Given their excellent stability and unique 1D nanostructure, acid-corroded TiO₂ nanobelts are a promising support material for constructing high-performance composite photocatalysts for nitrogen fixation.
