Efficient hydrogen evolution and rapid degradation of organic pollutants by robust catalysts of MoS2/TNT@CNTs

Electrocatalytic Performance of Titania Nanotube Arrays Coated with MoS2 by ALD toward the Hydrogen Evolution Reaction

“…Titanium oxide nanotube arrays (TNTAs) are a type of vertically aligned, highly ordered, high-surface area nanostructure that can be economically fabricated by anodic anodization of titanium metal. − Recently, TNTAs have been used in combination with MoS 2 materials fabricated by a variety of methods, such as hydrothermal synthesis, Mo sulfurization, and electrochemical deposition, to build heterostructures for water splitting. − The highly ordered tubular structure not only increases the number of active sites exposed to the electrolyte, it can also facilitate reactant supply and product removal along straight pores with respect to typical powder-based catalyst beds featuring long diffusion paths along disordered pores. However, those MoS 2 synthesis methods are not able to coat the highly tubular TNTAs with an accurate control of the MoS 2 loading.…”

Photodecoloration of Methyl Orange Solution Assisted by ZrS3 Powders

“…Semiconductor photocatalysis is an important option for solar energy conversion and pollutant degradation according to the idea of green chemistry. For purposes of degradation of the pollutants, a known set of catalysts is already designed [16]: double layered hydroxides [17], titanium dioxide [18], composites based on TiO2 [19], other oxides (ZnO [20], WO3 [21]), composites with oxides [22-24, 25, 26], as well as composites with MoS2 [27][28][29].…”

Z-Scheme MoS2/TiO2/graphene nanohybrid photocatalysts for visible light-induced degradation for highly efficient water disinfection and antibacterial activity

“…15 Graphene has been considered as an electron mediator for the heterostructure as a means to enhance the photoelectrochemical properties of the host media and enhance the photodegradation efficiency with visible light irradiation. 16,17 Various schemes have been suggested to improve the capability of photocatalysts; among them, hydrothermal technology is most generally followed for producing nanocomposites or nanohybrids. 18,19 Our previous studies have confirmed that MoS 2 -based nanomaterials exhibit better photocatalytic capability toward the removal of heavy metal ions, antibiotics, and organic pollutants.…”
