Highly stable 1T-MoS₂ by magneto-hydrothermal synthesis with Ru modification for efficient hydrogen evolution reaction

Abstract

Ru/1T-MoS2 with excellent hydrogen evolution activity were designed by a two-step method of phase engineering and noble metal modification. The reasons behind its excellent hydrogen evolution activity were revealed experimentally and theoretically.

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

“…Generally, the peaks at 284.7, 381.9, and 406.9 cm −1 are assigned to the E 1g , E 1 2g , and A 1g phonon modes of 2H-MoS 2 , and the peaks at 153.2, 226.4, and 336.7 cm −1 are indexed to the J 1 , J 2 , and J 3 phonon modes of 1T-MoS 2 . 35 In Fe 2 O 3 @C@1T/2H-MoS 2 , three peaks appear at 226.4, 284.7, and 336.7 cm −1 , clearly indicating a mixed 1T- and 2H-phase in the as-prepared MoS 2 . After calcination, the peaks at 226.4 and 336.7 cm −1 disappear, while two peaks at 381.9 and 406.9 cm −1 are observed, suggesting the conversion of the 1T-phase to the 2H-phase.…”

1T MoS2/CoS2 heterostructures enabling enhanced resistive switching behavior in sodium alginate-based flexible memristors

“…The observed lattice spacing in the regions marked by orange lines is 0.92 nm, corresponding to the (002) plane spacing of 1T MoS 2 . 42,43 In contrast, the region marked by the white line shows a lattice spacing of 0.24 nm, corresponding to the (210) plane spacing of CoS 2 . 39,44 The interface is marked with a red dotted line.…”

Novel magneto-electrocatalyst Cr2CO2-MXene for boosting nitrogen reduction to ammonia

“…However, there is adsorption competition between H + and N 2 at the reaction site at the defect during the first protonation from *N 2 to *NNH under acidic conditions. 50 The exposed Cr atoms at the defect may have a tendency to be more involved in the HER, which is detrimental to the NRR pathway. To further verify the eNRR performance of Inter-AFM magnetically ordered Cr 2 CO 2 , this work compares the potentials of the first protonation on N 2 ( U *NNH ), the protonation of hydrogen ( U *H ) on the Cr atom site, and the adsorption energies of N 2 and H + .…”
