Invention

Problem

Methods for producing graphitic carbon-nitride and metal-oxide composites can suffer from low yield, high cost, inefficient processing, agglomeration, limited surface area, and poor dispersion of active materials.

Why it matters

A controlled hybrid-material synthesis could support evaluation of porous carbon-nitride/oxide systems for energy-storage or catalytic research, provided composition, electrochemical behavior, durability, and manufacturability are independently verified.

Approach

The method combines magnesium, aluminum, and molybdate salts with a carbon source, removes water, calcines the precursor, then grinds it with urea and heats it to form a g-C3N4/MoO3/MgAl2O4 nanocomposite.

Who may benefit

Potential beneficiaries include supercapacitor-material researchers, electrochemical laboratories, photocatalyst developers, advanced-ceramics groups, and manufacturers studying multi-stage thermal synthesis of carbon-nitride/oxide composites.

Potential value

The disclosure specifies feed salts, carbon-source options, solvent-removal threshold, two heat-treatment windows, urea ratio, phase composition, mass relationships, and pore or diffraction characteristics for a defined hybrid powder.

Background

Supercapacitor electrodes benefit from surface area, electrical transport, chemical stability, and accessible sites for charge storage. Graphitic carbon nitride is investigated because it can absorb visible light and can be structurally modified, but conventional synthesis may yield agglomerated material with limited area or poor active-phase dispersion. The patent frames low yield, cost, and process efficiency as continuing limitations and proposes a carbon-nitride composite with molybdenum oxide and magnesium aluminate made through sequential drying, calcination, urea grinding, and heating.

Technology overview

Magnesium, aluminum, and molybdate salts are combined within five mole percent of stoichiometric proportions in an aqueous solvent containing menthol or dextrose. After at least 99.5 wt.% of the solvent is removed, the solid is ground and calcined at 600–800 °C for two to four hours. It is then ground with two to one hundred parts urea per part solid and heated at 550–650 °C. The resulting composite contains g-C3N4, MoO3, and MgAl2O4 in specified mass ranges and has defined pore and diffraction characteristics.

Potential applications

Potential supercapacitor electrode-material research after electrochemical validation.
Potential photocatalyst development using the carbon-nitride/oxide hybrid.
Potential platform for porous hybrid-material characterization studies.
Potential thermal-process development for multi-phase nanocomposite powders.

Evidence-supported advantages

Combines g-C3N4, MoO3, and MgAl2O4 in specified mass relationships.
Defines solvent-removal, calcination, urea, and final-heating parameters.
Specifies BET area, pore diameter, and pore-volume ranges.
Provides phase-identification criteria based on diffraction measurements.

Development stage

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

Commercial opportunity

The synthesis may be relevant to suppliers of research-grade electrode, catalyst, or hybrid ceramic powders. Commercial development should verify phase purity, batch consistency, pore structure, electrochemical or catalytic performance, cycling stability, thermal energy demand, precursor safety, waste handling, scale-up yield, integration into a device or process, and comparative economics.
