TL;DR: Novel Se-rich MoSe2 nanosheets synthesized using a hydrothermal reaction, displaying much enhanced HER performance at the Se/Mo ratio of 2.3, based on first-principles calculations.

TL;DR: Analysis of X-ray photoelectron and absorption spectra of the catalysts show that the MoS2 well retained its metallic 1T' phase, which guarantees good electrical conductivity during the reaction.

TL;DR: G Gibbs free energy along the reaction path indicates that the best HER performance of nanosheets with 10% Mo originates from the Mo-Mo pair that forms Mo-H when there are adjacent Se vacancies.

TL;DR: A deeper understanding is provided into how TM doping can provide the catalytically active sites in these ReSe2 nanosheets synthesized using a solvothermal reaction.

TL;DR: unique MoS2 layered nanostructures intercalated with dimethyl-p-phenylenediamine with various concentrations, synthesized by a one-step hydrothermal reaction, demonstrating how the phase control of TMDs can be effectively achieved by the intercalation of electron-donating molecules.
