The method for preparing the nano-quantum dot includes the following steps: rapidly solidifying a high-temperature melt in which a carrier corresponding to a target product ion/atomic group/molecular group is dissolved to obtain a carrier in which the target product nano-quantum dot is embedded. The nano-quantum dot material is prepared by using the method. The nano-quantum dot material is applied to the fields of luminescent devices, optical biological marks, disease detection, semiconductors or photoelectricity. Moreover, a quantum dot article containing the nano-quantum dot material is provided.

Producing hydrogen and carbon from hydrocarbons in a single-step process is described. A feedstock including natural gas or other light (e.g., <C5) hydrocarbons is introduced to a plasma reformer. The plasma reformer typically includes a non-thermal plasma. The plasma separates hydrogen from the carbon of the feedstock, yielding H2 and carbon black. The carbon is separated from the H2, and the H2 is further used as fuel (e.g., generating electricity via fuel cell) either contemporaneously or at a later time, stored, pressurized, or dispensed to a vehicle. Excess electricity generated form the H2 is stored in a battery, and excess is either stored or pressurized. Carbon black is further condensed to reduce volume for storage or transport.

A system and process for producing doped carbon nanomaterials is disclosed. A carbonate electrolyte including a doping component is provided during the electrolysis between an anode and a cathode immersed in carbonate electrolyte contained in a cell. The carbonate electrolyte is heated to a molten state. An electrical current is applied to the anode, and cathode, to the molten carbonate electrolyte disposed between the anode and cathode. A morphology element maximizes carbon nanotubes, versus graphene versus carbon nano-onion versus hollow carbon nano-sphere nanomaterial product. The resulting carbon nanomaterial growth is collected from the cathode of the cell.
