Single-Step Production of a TiO(2)@MoS(2) Heterostructure and Its Applications as a Supercapacitor Electrode and Photocatalyst for Reduction of Cr(VI) to Cr(III)

[Image: see text] In this study, we have reported a one-step synthesis of a TiO(2)@MoS(2) heterostructure. TiO(2)@MoS(2) was synthesized using a facile and cost-effective method. The as-synthesized TiO(2)@MoS(2) heterostructure was characterized by suitable spectroscopic techniques. The obtained TiO...

description [Image: see text] In this study, we have reported a one-step synthesis of a TiO(2)@MoS(2) heterostructure. TiO(2)@MoS(2) was synthesized using a facile and cost-effective method. The as-synthesized TiO(2)@MoS(2) heterostructure was characterized by suitable spectroscopic techniques. The obtained TiO(2)@MoS(2) was utilized as a supercapacitor electrode material. Electrochemical studies show that the TiO(2)@MoS(2) heterostructure possesses a specific capacitance of 337 F/g at a current density of 1 A/g in an aqueous solution. Furthermore, an application as a photocatalyst for the photoreduction of toxic hexavalent chromium was reported for the first time. This heterostructure showed the photoreduction of Cr(6+) to Cr(3+) in 120 min with formic acid as a scavenger under direct sunlight. A plausible mechanism of photoreduction of Cr(6+) to Cr(3+) under natural sunlight irradiation using TiO(2)@MoS(2) is proposed.
