A photocatalyst of high-performance hierarchical nitrogen-doped MoS2 (N-MoS2) microsphere was fabricated by an in situ hydrothermal method in the presence of cetyltrimethylammonium bromide (CTAB). The as-prepared N-MoS2 microsphere was self-assembled by extremely thin interleaving petals, where CTAB acts as a nucleation site for the formation of the interleaving petals due to the strong interaction between CTA+ and [Formula: see text]. N-MoS2 showed higher N2 fixation ability (101.2 [Formula: see text] mol/g(cat)h) than the non-doped MoS2 under the visible light irradiation, and the improved photocatalytic activity could be ascribed to that the doped N narrows the band gap, and the surface reflecting and scattering effect caused by the hierarchical structure enhance the light adsorption. The trapping experiment of active species was also investigated to evaluate the role of photogenerated electrons in the photocatalytic reaction process. Meanwhile, the possible mechanism for the formation and excellent photocatalytic performance of N-MoS2 microsphere were also presented.

Key Steps

Abstract TiO2 photocatalyst was prepared with a sol-gel method and its characterizations were analyzed, then TiO2 photocatalytic reduction for Cr6+ was investigated in visible light irradiation and reduction mechanism were deduced lastly. Prepared TiO2 is anatase and bandgap is about 2.95 eV. Experimental results display that almost 100% Cr6+ is removed by visible-light-driven TiO2 photocatalytic reduction after 120 min when Cr2O72− initial concentration is 1.0 mg·L−1, TiO2 dosage is 1.0 g·L−1 and pH value is 3. In acidic aqueous solution, HCrO4− is the dominant existing form of Cr6+ and adsorbed by TiO2, forming a complex catalyst HCrO4−/TiO2 which wavelength enlarges to visible light zone, proved by UV-Vis DRS. Based on XPS data, it can be deduced that Cr6+ is adsorbed on the surface of TiO2 and then reduced to Cr3+in situ by photoelectrons. Self-assembly of HCrO4−/TiO2 complex catalyst and self-reduction of Cr6+in situ are the key steps to start visible-light-driven TiO2 photocatalytic reduction. Furthermore, TiO2 photocatalytic reduction for Cr6+ fits well with pseudo first-order kinetics and has potential application to treat chemical industrial wastewater.
