We report a facile and inexpensive wet synthetic method to electrocatalytically active, B-substituted graphene (B-SuG) by controlled substitution of the C atoms of graphene with B atoms using BH ₃ -THF. The resulting material is shown to serve as an efficient metal-free electrocatalyst for hydrogen evolution reaction (HER).

A synthetic route to low-density porous Ni-doped Co₃O₄ nanomaterials that show stable and superior electrocatalytic activity for O₂ evolution reaction is reported. The materials are prepared via thermal treatment of “pre-synthesized” metal ions-embedded graphitic C₃N₄-based polymers.

Lithium–sulfur batteries (LSBs) are one of the most promising next-generation batteries because they have higher theoretical capacities, lower cost, and smaller environmental impact than lithium-ion batteries (LIBs).

As a novel carbon allotrope, carbon quantum dots (CQDs) have been investigated in various fields including photocatalysis, bio imaging, optoelectronics, energy and photovoltaic devices, biosensing and drug delivery owing to their unique optical and electronic properties. Especially, CQDs’ excellent sunlight harvesting ability, tunable photoluminescence (PL), up-converted photoluminescence (UCPL) and efficient photo-excited electron transfer have enabled their applications in photocatalysis. This work focuses on the recent progress on CQDs related materials’ synthesis, properties and applications in photocatalysis.
