Unlike conventional tube furnace devices, Joule heating is a typical non-radiative heating method that does not require heating wires. A Joule heating reactor is a device that utilizes the Joule heating effect to achieve rapid temperature rise (up to 3000+ °C) in extremely short time (1 s-10 s, minimum 80 ms).

1: Continuous Low-Carbon Production of Graphene

By developing an integrated automatic system and pyrolysis-FJH coupling technology, a continuous and low-carbon production of high-value flash graphene from biomass waste has been realized. This not only improves the recycling rate of resources and production efficiency but also reduces environmental impact. It demonstrates application potential in multiple fields such as catalysis, energy storage, and environmental remediation. Moreover, it has significant advantages in terms of economic benefits and environmental sustainability, providing an innovative solution for promoting the industrial application of graphene materials and achieving green production.

2: Flash Joule Synthesis of High-Entropy Alloys

The flash joule heating technology is used to synthesize high-entropy alloys. The specific method is as follows: appropriate carbon sources (such as activated carbon or carbon black) are mixed with metal salt precursors at high temperatures. The carbon sources burn at temperatures exceeding 2000K to generate thermal shock, rapidly reducing the metal salts into metal atoms. These atoms form a solid solution alloy structure at high temperatures and are rapidly cooled (10⁵ K·s⁻¹) to prepare high-entropy alloys. This method can achieve rapid diffusion and uniform distribution of metal atoms in a short time to form alloys with uniform composition, and the microstructure and properties of the alloys can be regulated by adjusting the type and amount of carbon sources.  

3: Heavy Metal Extraction from Coal Ash

The flash joule heating (FJH) technology can raise the temperature to approximately 3000°C in an extremely short time, efficiently removing heavy metals such as arsenic, cadmium, cobalt, nickel, and lead from coal fly ash, with a removal rate of 70-90%. The treated coal fly ash (CFA) can be used as a substitute for Portland cement, not only enhancing the strength of the cement but also reducing heavy metal leakage in acidic environments. This technology performs excellently in terms of energy efficiency and cost-effectiveness, with an electrical energy cost of approximately $21 per ton. Life cycle analysis shows that the reuse of CFA can reduce greenhouse gas and heavy metal emissions, with energy consumption effectively balanced compared to landfilling, and the technology can also be extended to the decontamination treatment of other industrial wastes.

A study uses biological waste such as human hair to prepare graphene carbon materials through instantaneous heating technology for use as anodes in high-performance lithium-ion batteries. This method improves the sustainability of material production, reduces costs and environmental impact, enhances supply chain resilience, provides a new approach for battery performance optimization, and opens up a new research field for converting waste into useful materials.

5: Synthesis of Iron-Based Catalysts for Efficient Water Treatment

A new iron-based material is synthesized by carbon-assisted instantaneous joule heating, which combines the characteristics of single atoms and high-index facet nanoparticles. It significantly enhances the ability to generate hydroxyl radicals during persulfate activation, can efficiently degrade organic pollutants such as antibiotics in medical wastewater, and reduce the environmental transmission of antibiotic resistance genes, showing application potential in the fields of water treatment and environmental protection.

6: Ultrafast Densification of Cermet Materials

Joule heating technology provides a rapid and energy-efficient method for the sintering of cermet materials such as tungsten carbide (WC), allowing the green compact to reach high temperatures in an extremely short time, accelerating the densification process, significantly improving material density and mechanical properties, and maintaining microstructural uniformity, which is of great significance for the manufacture of high-performance cemented carbides and wear-resistant materials.

7: Conversion of Waste Plastics into Clean Hydrogen

The rapid joule heating technology is used to convert waste plastics into clean hydrogen and high-purity graphene, achieving zero carbon emissions. Moreover, the sale of graphene by-products can make the production cost of hydrogen negative, providing an economically feasible and environmentally friendly solution for clean energy production and waste recycling.
