Due to their enhanced light harvesting, favored interfacial charge transfer and excellent proton reduction activity, hybrid photocatalysts of metallic 1T-MoS nanosheets and inorganic-ligand stabilized CdSe/ZnS QDs obtained via a self-assembly approach can produce H gas with a rate of ∼155 ± 3.5 μmol h mg under visible-light irradiation (λ = 410 nm), the most exceptional performance of solar H evolution using MoS as a cocatalyst known to date.

The lack of stable anode materials with high capacity and fast redox kinetics has hindered the application of lithium-ion batteries (LIBs) for energy storage. Metal-phase molybdenum disulfide (1T-MoS) is recognized as a promising energy storage material because of its combination of excellent physical and electrochemical properties. In this paper, we report the insertion of ammonium ions (NH) into the MoS interlayer and effective complexation with graphene oxide (GO).

A "signal-on" electrochemiluminescence (ECL) immunosensor has been proposed for detecting carbohydrate antigen 153 (CA153) based on the dual MOFs sandwich strategy. The conductive and porous substrate consisting of 1T-MoS and two-dimensional conductive metal-organic framework (MOF, Ni-HAB) was anchored onto the glassy carbon electrode (GCE) to label the capture antibody (Ab1), and the luminescence-functionalized MOF (Ru(bpy)@UiO-66-NH) was utilized to immobilize the detection second antibody (Ab2) to construct a "signal-on" responsive sandwich-type electrochemiluminescence immunoassay. Meanwhile, tripropylamine (TPA) acts as the co-reactant and provides a luminescence system for Ru(bpy)@UiO-66-NH.

MiRNA-155 is a typical biomarker for breast cancer. Since its low concentration in the physiological environment and the limitations of conventional miRNA detection methods like Northern imprinting and RT-qPCR, convenient, real-time, and rapid detection methods are urgently needed. In this work, an electrochemical biosensor was constructed based on the flower-like MoSe@1T-MoS heterojunction electrode material and specific RNA recognition probes, which can realize the rapid determination of miRNA-155 content with a wide detection range from 1 fM to 1 nM and a limit of detection (LOD) as low as 0.

Uniform distribution of electrochemically active transition metal compounds on carbon cloth can effective improve their hydrogen evolution reaction (HER) performance, however, harsh chemical treatment of carbon substrates is always unavoidable during this process. Herein, a hydrogen protonated polyamino perylene bisimide (HAPBI) was used as interface active agent for the in situ growth of rhenium (Re) doped MoS nanosheets on carbon cloth (Re-MoS/CC). HAPBI contains a large conjugated core and multiple cationic groups and has been shown to be an effective graphene dispersant.

Metal phase molybdenum disulfide (1T-MoS ) is considered a promising electrocatalyst for hydrogen evolution reaction (HER) due to its activated basal and superior electrical conductivity. Here, a one-step solvothermal route is developed to prepare 1T-MoS with expanded layer spacing through the derivatization of a Mo-based organic framework (Mo-MOFs). Benefiting from N,N-dimethylformamide oxide as external stress, the interplanar spacing of (002) of the MoS catalyst is extended to 10.
