摘要:The invention discloses a method for the synthesis of monodispersed luminescent quantum dots of transition metal dichalcogenides (TMDC), single- or few-layered, using a single-step electrochemical exfoliation that involves dilute ionic liquid and water. The method disclosed helps to obtain nanoclusters of TMDC of desired size including small sizes ranging up to 6 nm, by varying the concentration of the electrolyte and the applied DC voltage. The invention further discloses a method by which mono- or few-layered luminescent transition metal dichalcogenides can be directly deposited onto conducting substrates in a uniform manner. The monodispersed single- or few-layered luminescent TMDC and electro-deposited substrates exhibit improved electronic conductivity and new active sites, making them suitable as high-performance electrocatalysts in hydrogen evolution reactions in solar water-splitting applications and also as electrodes for solar cell applications.

权利人:OHIO STATE INNOVATION FOUNDATION
摘要:Methods for the scalable and systematic synthesis of semiconducting Chevrel phase compounds via self-propagating high temperature synthesis (SHS) are provided. The provided methods utilize elemental precursors not utilized by typical synthesis methods. The precursors may include molybdenum (Mo), molybdenum disulfide (MoS 2 ), and a ternary cation. In various aspects, the ternary cation may be copper (Cu), iron (Fe), or nickel (Ni). The utilization of the provided precursors and SHS decreases the time it takes to synthesize Chevrel phase compounds as compared to typical heat treatment methods.

摘要:The present invention provides a general salt-assisted chemical vapour deposition method for phase-controllable synthesis of 1T′ and 2H-phase transition metal dichalcogenide (TMD) monolayer crystals. The method comprises: mixing a transition metal compound powder and a salt powder to form a precursor; placing a substrate on top of the precursor; placing the precursor and the substrate at a center position in a chemical vapour deposition (CVD) furnace; placing a chalcogen powder at an upstream position relative to the precursor along a gas-flow direction in the CVD furnace; heating up the CVD furnace to a growth temperature within the heat-up time; keeping the CVD furnace at the growth temperature for a growth time under a mixed gas flow of H2 and Ar. The optical and electrical characterizations reveal the phase-dependent in-plane isotropy and anisotropy of the as-synthesized 2H and 1T′-phase crystals. The 1T′-TMD monolayer crystals demonstrate much-improved phase transition temperatures.

摘要:This invention relates to a process for the electrochemical synthesis of ammonia (NH3) and the ammonia produced thereby. Ammonia is synthesized by the electrochemical reduction of nitrogenous materials such as nitrogen or nitrates (NO3-) using metal phthalocyanine such as iron phthalocyanine (FePc) or β-cobalt phthalocyanine (CoPc) or iron phthalocyanine-molybdenum disulfide (FePc-MoS2) or cobalt phthalocyanine- carbon nitride (CoPc-C3N4) catalyst at very low pressure and room temperature by applying low potential.
