Abstract

Abstract: In this work, we report RuO2 -loaded TiO2 –MXene hybrid nanostructure as a promising photocatalyst possessing remarkable activity for photocatalytic nitrogen fixation in water at room temperature. The MXene was synthesized by HF etching of the precursor Ti3 AlC2 and used as the substrate for the growth of RuO2 nanoparticles and TiO2 through a hydrothermal reaction. The benign activity is mainly attributed to the synergetic effect among MXene, TiO2, and RuO2 in photocatalytic ammonia synthesis by combining light harvesting and nitrogen activation. Graphical abstract: Image 1 Highlights: RuO2 nanoparticles were hydrothermally loaded onto TiO2 –Ti3 C2 Tx MXene hybrid structure. We explore their photocatalytic properties in reduction of nitrogen into ammonia. Ultrasmall RuO2 nanoparticles were hydrothermally synthesized on TiO2 -loaded MXene. The hybrid was used in photocatalytic nitrogen fixation under Xe-lamp irradiation.
