摘要:The object of the invention is a process for the synthesis of nanotubes of transition metal dichalcogenides, of fullerene-like nanostructures of transition metal dichalcogenides, of nanotubes of transition metal dichalcogenides, filled with fullerene-like nanostructures of transition metal dichalcogenides, of quasi one-dimensional structures (nanowires, microwires and ribbons) of transition metal oxides and of quasi one-dimensional structures of transition metal dichalcogenides, consisting of fine crystallites of transition metal dichalcogenides. The process is characterized in that the synthesis occurs by the chemical transformation of quasi one-dimensional compounds with a sub-micron diameter, described by the formula M 6 C y H z , 8.2

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:The present invention provides a one-pot process of synthesis of phenyl naphthalene compounds that are employed as heat transfer agents. More particularly, the present invention provides a process of preparation of 1-phenylnaphthalene and 2-methyl-1-phenylnaphthalene using refinery spent catalyst. These molecules are known for application as synthetic heat transfer fluids that deliver outstanding performance and thermal stability at continuously high operating temperatures. The reaction is carried out in aqueous medium using a spent catalyst which is a palladium based charcoal catalyst as obtained from various refinery processes. Further, the present invention provides a heat resistant formulation using the synthesized polyhydrocarbons, wherein the formulation is optimized with a free radical scavenger.

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.

摘要:A process for gas-phase synthesis of titanium dioxide aerosol gels with controlled monomer size and crystalline phase using a diffusion flame aerosol reactor operated in a buoyancy-opposed configuration is disclosed. The process includes introducing a precursor stream into a diffusion flame aerosol reactor, introducing a fuel stream into the reactor, combusting the precursor stream and the fuel stream in a flame to form at least one nanoparticle, and operating the reactor in a down-fired buoyancy-opposed configuration to produce the aerosol gel.

摘要:The present disclosure is generally directed to a single-step synthesis of nanostructured thin films by a chemical vapor and aerosol deposition (CVAD) process. The present disclosure is also directed to methods for controlling the morphology of the nanostructured thin films. The films can be used, for example, in lithium ion and/or sodium ion battery electrodes, solar cells and gas sensors.
