A unique approach for the synthesis of nonstoichiometric, mesoporous molybdenum oxide (MoO 3– x ) with nanosized crystalline walls by using a soft template (PEO‐ b ‐PS) method is introduced. The as‐synthesized MoO very active and stable (durability > 12 h) electrochemical hydrogen evolution reaction (HER) under both acidic alkaline conditions. intrinsic 3 serves as an HER electrocatalyst without assistance carbon materials, noble metals, or MoS 2 materials. results from transmission...
We report a facile synthetic protocol to prepare mesoporous FeS2 without the aid of hard template as an electrocatalyst for hydrogen evolution reaction (HER). The materials with high surface area were successfully prepared by sol–gel method following sulfurization treatment in H2S atmosphere. A remarkable HER catalytic performance was achieved low overpotential 96 mV at current density 10 mA·cm–2 and Tafel slope 78 per decade under alkaline conditions (pH 13). theoretical calculations...
Fluorescent carbon nanoparticles were synthesized from a single precursor and applied for explosives detection.
A direct and effective approach is proposed to fabricate bimetallic phosphide Ni2P–Cu3P with controllable phase composition distribution for catalytic hydrogen evolution reaction (HER). Unlike previously reported precursors, a porous Ni–Cu alloy incorporated graphitic carbon (NiCuC) prepared via powder metallurgy employed herein, the generated Ni2P–Cu3P@NiCuC possesses hierarchical structure due high porosity tunable Ni/Cu ratio of precursor. With an optimal Cu content 30.0 wt %, catalyst...

Electrocatalysis of water is a scalable and easily available source the production hydrogen (H2), future energy carrier. This drive for clean inspired us to develop an inexpensive, readily producible, highly active, stable catalyst replace current state art platinum catalysts. Building on promising evolution reaction (HER) activity many pyrites, their structural tuning by different metals nonmetals has been found be effective in several instances. We present here one such effort partial...
Significance Electrochemical reduction of CO 2 to useful chemicals or fuels is critical closing the carbon cycle and preventing further deterioration environment/climate. This work addresses low-energy-efficiency problem limited by sluggish oxygen evolution reaction (OER) on anode side. The only active OER catalysts for coupling in neutral conditions are based noble metals such as Ir, Ru, gold. Herein, we developed a nonprecious-metal-based with higher activity stability than those...
Pursuing cost-effective water-splitting catalysts is still a significant scientific challenge to produce renewable fuels and chemicals from various feedstocks.

Abstract The increasing demand of emerging technologies for high energy density electrochemical storage has led many researchers to look alternative anode materials graphite. most promising conversion and alloying do not yet possess acceptable cycle life or rate capability. In this work, we use tin oxide, SnO 2 , as a representative material explore the influence graphene incorporation In-doping increase electronic conductivity concomitantly improve capacity retention life. It was found that...
