The development of efficient non-noble-metal electrocatalysts is critical importance for clean energy conversion systems, such as fuel cells, metal-air batteries, and water electrolysis. Herein, uniform Co9S8@MoS2 core-shell heterostructures have been successfully prepared via a solvothermal approach, followed by an annealing treatment. Transmission electron microscopy, X-ray absorption near-edge structure, photoelectron spectroscopy measurements reveal that the structure can introduce...

Manipulating the reversible redox chemistry of transition metal dichalcogenides for energy storage often faces great challenges as it is difficult to regulate discharged products directly. Herein we report that tensile-strained MoSe2 (TS-MoSe2) can act a host transfer its strain corresponding product Mo, thus contributing regulation Gibbs free change (ΔG) and enabling sodium mechanism.

The atomic-local environment of catalytically active sites plays an important role in tuning the activity carbon-based metal-free electrocatalysts (C-MFECs). However, rational regulation is always impeded by synthetic limitations and insufficient understanding formation mechanism catalytic sites. Herein, possible cleavage carbon nanotubes (CNTs) through crossing points during ball-milling proposed, resulting abundant CNT tips that are more susceptible to be modified heteroatoms, achieving...

Our theoretical and experimental results reveal that these Se-vacancies can efficiently activate optimize the basal planes of MLNSs. As expected, optimized catalyst exhibits efficient electrocatalytic hydrogen evolution.

Non-precious-metal (NPM) catalysts often face the formidable challenge of a trade-off between long-term stability and high activity, which has not yet been widely addressed. Herein we propose distinct molecule-selective fence as promising concept to solve this activity-stability trade-off. The encloses catalyst prevents species poisonous from reaching it, but allows catalytic reaction-related diffuse freely. We constructed CoS2 layer on external surface highly active cobalt-doped MoS2 ,...
