摘要： An embodiment of the present invention provides a catalyst with maximized activity and stability through synthesizing carbon quantum dots with transition metal elements introduced based on carbon compound monomers containing nitrogen elements that have excellent bonding ability with transition metals. By introducing low-cost transition metal atoms into nano carbon quantum dots (CQDs), a type of highly stable carbon nanostructure, the activity and stability of the hydrogen generation catalyst reaction through water electrolysis are simultaneously increased, so that an economical, highly active, highly stable catalyst for electrochemical hydrogen generation reaction can be manufactured.

摘要： A method for manufacturing a composite in which at least one of an elemental metal or a metal compound is carried on a carrier. The method includes exposing a dispersion liquid containing a solvent and the carrier to a reduced-pressure environment of less than 80 kPa (absolute pressure) at normal temperature, preparing a raw material mixture liquid by mixing a metal-ion supplying agent which is a metal ion source of the elemental metal or the metal compound with the dispersion liquid, and mixing a reducing agent with the raw material mixture liquid and causing the elemental metal or the metal compound to be carried on a surface of the carrier.

摘要： Provided are a method for preparing a vertical branched graphene comprising treating a pristine vertical graphene with an inert plasma in the absence of an introduced carbon source to develop a vertical branched graphene. The method may also include pre-treating a substrate surface with an inert plasma; depositing a pristine vertical graphene onto the substrate surface by contacting the substrate surface with a deposition plasma comprising a carbon source gas for a deposition period. Also provided are a vertical branched graphene attached to a substrate surface, the vertical branched graphene having a trunk portion extending from the substrate surface, said trunk possessing an increased degree of branching as the distance from the substrate surface increases; and a freestanding branched graphene with a proximal end and a distal end, the proximal end comprising a trunk portion, the trunk portion possessing and increased degree of branching as the distance from the proximal end increases and the distance to the distal end decreases.
