Hybrid Nanomaterial for Energy Storage

Official patent title

Method of manufacturing a nanocomposite

Arabic title: طريقة لتصنيع مركب نانوي

Invention

Problem

Graphitic carbon-nitride composite synthesis can produce agglomeration, limited surface area, poor dispersion of active phases, and uncertain scalability, cost, stability, or durability for practical energy-storage use.

Why it matters

A bounded preparation route for a carbon-nitride/vanadium-oxide/spinel composite could enable systematic materials evaluation, but electrochemical performance, durability, process economics, and production consistency require independent verification.

Approach

The method combines magnesium, aluminum, and metavanadate salts with menthol or dextrose, dries and calcines the precursor, then grinds it with urea and reheats it to form g-C3N4, V2O5, and MgAl2O4.

Who may benefit

Potential beneficiaries include supercapacitor and electrode researchers, photocatalyst developers, advanced-materials laboratories, oxide-powder manufacturers, and process engineers evaluating staged thermal synthesis.

Potential value

The disclosure defines stoichiometric tolerances, solvent-removal level, two heat-treatment windows, urea loading, target phase ratios, pore ranges, and diffraction signatures for a specific three-component nanocomposite.

Background

Energy-storage materials are expected to provide accessible surface area, electrical transport, chemical stability, and durable charge-storage behavior. Graphitic carbon nitride is studied as a visible-light-responsive and structurally tunable carbon material, yet established preparation methods may yield agglomeration, limited area, or poor dispersion. The disclosure also identifies cost-effective scale-up and long-term stability as unresolved challenges. It addresses these issues through a sequential salt, carbon-source, calcination, urea, and reheating process targeting a g-C3N4/V2O5/MgAl2O4 composite.

Technology overview

Magnesium, aluminum, and metavanadate salts are combined within five mole percent of stoichiometry in an aqueous menthol- or dextrose-containing solvent. At least 99.5 wt.% of the water is removed, and the ground solid is calcined at 600–800 °C for two to four hours. The product is ground with two to one hundred parts urea per part solid and heated at 550–650 °C for 15–90 minutes. The target composite contains g-C3N4, V2O5, and MgAl2O4 in defined mass relationships.

Potential applications

Potential supercapacitor electrode-material research after performance validation.
Potential visible-light photocatalyst material studies.
Potential porous composite platform for electrochemical research.
Potential process-development work for multi-phase hybrid powders.

Evidence-supported advantages

Combines g-C3N4, V2O5, and MgAl2O4 in bounded mass ratios.
Defines two controlled thermal-processing stages.
Specifies BET area and BJH pore characteristics.
Provides SAED and XRD criteria for phase characterization.

Development stage

Patent publication with a described synthesis and material characterization; independent validation and commercialization were not established.

Commercial opportunity

The process may be relevant to research-material suppliers and developers of electrode or photocatalyst powders. Advancement requires independent testing of phase composition, batch repeatability, electrochemical and optical response, cycling durability, precursor and energy costs, safe processing, waste streams, scale-up yield, device integration, and performance against existing materials.
