One-pot hydrothermal approach towards 2D/2D heterostructure based on 1 T MoS2 chemically bonding with GO for extremely high electrocatalytic performance

Hierarchical Electrodes of MoS 2 Nanoflakes Wrapped on CNTs in Wood-Derived Porous Carbon Frameworks for a High-Performance Hydrogen Evolution Reaction

“…33 Essentially, MoO 3 and 1T-MoS 2 have similar lattice structures, so 1T-MoS 2 is easily produced when MoO 3 as the precursor is reduced to prepare MoS 2 . 24 The elemental mapping (Figure 2k) and EDX (Figure S10b) manifest that C, N, O, S, and Mo are all uniformly distributed on CNTs. Fe is distributed on both CNTs and MoS 2 nanoflakes as a result of dissolution, diffusion, and redistribution during the hydrothermal process.…”

“…Herein, the hexagonal 2H- and trigonal 1T- phases coexist, as marked by the white solid line and the red dashed line, respectively . Essentially, MoO 3 and 1T-MoS 2 have similar lattice structures, so 1T-MoS 2 is easily produced when MoO 3 as the precursor is reduced to prepare MoS 2 . The elemental mapping (Figure k) and EDX (Figure S10b) manifest that C, N, O, S, and Mo are all uniformly distributed on CNTs.…”

“…MoS 2 nanoflakes were in situ grown on Fe/Fe 3 C/CNT@GW via the hydrothermal method. 24 Typically, 0.36 g of MoO 3 , 0.42 g of CH 3 CSNH 2 , and 3.0 g of urea were melted in 35 mL of DI water and stirred for 1 h. Fe/Fe 3 C/ CNT@GW-5 was soaked into the mixed liquid for 2 h. Then, the solution containing Fe/Fe 3 C/CNT@GW-5 was heated in a 50 mL Teflon-lined autoclave at 200 °C for 18 h. After natural cooling to ambient, the Fe/Fe 3 C/CNT@MoS 2 @GW-2 sample was rinsed with DI water and dried. The synthesis of Fe/Fe 3 C/CNT@MoS 2 @GW-1 and Fe/Fe 3 C/CNT@MoS 2 @GW-3 followed a similar procedure except for the use of different total weights of Mo and S in precursors (0.26 and 1.3 g, respectively).…”

Photocatalytic generation of H2O2 over a Z-scheme Fe2O3@C@1T/2H-MoS2 heterostructured catalyst for high-performance Fenton reaction

“…There are two main MoS 2 phases: 2H semiconducting and 1T metallic phases. 25,26 In photocatalytic reactions, they display different functions. 27 Metallic 1T-MoS 2 possesses a high electrical conductivity and usually serves as an e − reservoir, while 2H-MoS 2 functions as a component in the heterojunction.…”

A solution-processed MoS2/graphene heterostructure mediated by a bifunctional block copolymer as a non-noble metal platform for hydrogen evolution

“…20 In a recent study, the excellent HER performance of MoS 2 /GO was ascribed to the metallic 1T phase domains of MoS 2 -based materials and strong interactions between the two counterparts, albeit the mechanisms taking place remain quite unclear. 21 However, all the aforementioned synthetic procedures involve the implementation of graphene derivatives and inorganic precursors of MoS 2 by solvothermal/hydrothermal methods, high-pressure autoclave methods and exposure to microwave irradiation. Consequently and as a significant handicap, these methodologies do not provide control over the morphology and chemical composition of the hybrids, especially those of MoS 2 ; therefore, there is limited insight not only regarding the chemical interaction of the counterparts, but also for the reasoning behind their synergism and thus the enhanced HER performance of the hybrids.…”
