Development of non-noble-metal catalysts for hydrogen evolution reaction (HER) with both excellent activity and robust stability has remained a key challenge in the past decades. Herein, first time, N-doped carbon-wrapped cobalt nanoparticles supported on graphene nanosheets were prepared by facile solvothermal procedure subsequent calcination at controlled temperatures. The electrocatalytic HER was examined 0.5 M H2SO4. Electrochemical measurements showed small overpotential only −49 mV...
Biomass-derived nitrogen self-doped porous carbon was synthesized by a facile procedure based on simple pyrolysis of water hyacinth (eichhornia crassipes) at controlled temperatures (600–800 °C) with ZnCl2 as an activation reagent. The obtained exhibited BET surface area up to 950.6 m2 g−1, and various forms (pyridinic, pyrrolic graphitic) were found be incorporated into the molecular skeleton. Electrochemical measurements showed that carbons possessed high electrocatalytic activity for ORR...

Most of the current methods for synthesis two-dimensional materials (2DMs) require temperatures not compatible with traditional back-end-of-line (BEOL) processes in semiconductor industry (450 °C).

Abstract Lithium–sulfur (Li–S) batteries, as one of the most promising “post‐Li‐ion” energy storage devices, encounter several intrinsic challenges: polysulfide dissolution and shuttle effect, poor sulfur utilization, lithiation‐induced expansion, lithium dendritic growth. These challenges must be resolved, associated mechanisms completely understood before practical applications Li–S batteries.
