High-temperature thermal shock and material modification: Yugeswaran Subramaniam et al. used thermal plasma technology to prepare high-entropy oxides and introduced oxygen vacancies through argon plasma, significantly improving their electrocatalytic performance. Dong Zhiguo et al. used flash Joule heating (FJH) technology to efficiently convert lignin into high-quality graphite carbon (LFG) and revealed its graphitization mechanism. Flash Joule Heating Machine (FJH) technology can also quickly heat the material to a high temperature, triggering the reorganization of the internal structure of the material and the formation of defects, and achieve precise control of the microstructure of the material. All three use the violent reaction conditions brought about by high-temperature thermal shock to promote efficient modification of the target material.
Rapid heating and performance optimization: Both thermal plasma technology and FJH technology have the characteristics of rapid heating, which can achieve structural transformation and performance optimization of materials in a short time. Plasma technology optimizes the electronic structure of high-entropy oxides and improves their electrocatalytic performance by introducing oxygen vacancies; FJH technology promotes the graphitization of lignin through rapid heating, improving the conductivity and stability of graphite carbon.
High efficiency and low cost: Both plasma technology and FJH technology are highly efficient and can complete the modification and preparation of materials in a shorter time, reducing production costs. Plasma technology achieves rapid modification of the material surface through plasma discharge, while FJH technology achieves rapid and efficient energy conversion by directly heating the material with electricity.
Environmental friendliness: FJH technology does not require the use of solvents or reaction gases during the material synthesis process, and has low energy consumption. It is an environmentally friendly preparation method. Although plasma technology will produce some active substances during the treatment process, its energy utilization rate is high and the treatment process is relatively clean.
Further optimization of catalyst performance: FJH technology can be applied to the subsequent treatment of high entropy oxide catalysts after plasma treatment. Through further rapid heat treatment, the metal particle size, distribution and interaction with the carrier of the catalyst can be optimized to improve its catalytic activity and stability.
Development of new materials: Combine the advantages of plasma technology and FJH technology to explore and develop new materials. For example, try to modify the surface of other types of metal oxides or composite materials through plasma technology, and then use FJH technology for rapid heat treatment and structural optimization to achieve higher performance and better application effects.
Optimization and standardization of process parameters: In-depth study of the synergistic mechanism of plasma technology and FJH technology in the material preparation process, optimize process parameters such as heating temperature, heating time, current density, etc. Establish a standardized process flow to ensure the stability and consistency of material performance, and provide reliable technical support for the commercial production and application of materials.
