High Temperature Thermal Shock and Material Synthesis: Dr. Yang Liu's team has successfully prepared highly dispersed face-centered cubic copper-cobalt alloy (Cu2.5Co) by rapidly heating carbon fiber paper preloaded with metal salts under argon and hydrogen atmospheres using Carbon Thermal Shock, realizing highly efficient electrocatalytic reduction of nitrate to make ammonia under ambient conditions.Flash Joule Heating Machine (FJH) technology is also capable of rapidly heating materials to high temperature to trigger the restructuring and defect formation of the internal structure of materials, achieving precise control of the microstructure of the materials. Flash Joule Heating Machine (FJH) is also capable of rapidly heating materials to high temperatures, triggering the reorganization of the internal structure of the material and the formation of defects, and realizing the precise control of the microstructure of the material. Both utilize the intense reaction conditions brought about by high temperature thermal shock to promote efficient synthesis of target materials.
Rapid heating and property optimization: Carbon thermal shock technology realizes the efficient preparation of Cu-Co alloys through rapid heating, optimizes their electronic structure and catalytic properties, and significantly improves the efficiency of ammonia production by nitrate reduction.FJH technology is also commonly used for rapid heating and property optimization in the preparation of other materials, for example, in the preparation of carbon-based materials, such as graphene, the defect density of the material and the electronic structure of the material can be adjusted through rapid heating, so as to optimize its electrical conductivity. electronic structure of the material, thus optimizing its electrical conductivity and chemical activity.
High efficiency and low cost: Carbon thermal shock technology can complete the preparation of alloys in a short period of time, which is highly efficient, while FJH technology, with its rapid heating and cooling characteristics, can significantly shorten the time of material preparation, improve the production efficiency and reduce the production cost. The combination of the two can further improve the efficiency and performance of material preparation, reduce production costs, and provide technical support for the large-scale production of high-performance catalytic materials.
Environmental friendliness: Carbon thermal shock technology avoids the long time energy consumption and environmental pollution problems in the traditional high temperature treatment process.FJH technology does not need to use solvents or reaction gases during the material synthesis process and has low energy consumption, which is in line with the current requirements of environmental protection and sustainable development.
Further optimization of material properties: FJH technology can be applied to the subsequent treatment of Cu-Co alloys treated by carbon thermal shock technology to optimize the crystal structure and defect distribution of the alloys and improve their catalytic activity and stability through further rapid heat treatment. For example, more uniform defect distribution and stronger metal-carrier interactions are realized by FJH technology to enhance the sintering resistance and long-term stability of the alloy.
Development of new catalytic materials: Combining the rapid synthesis capability of FJH technology and the structure modulation advantage of carbon thermal shock technology, explore the development of new catalytic materials. For example, try to put other types of metal or non-metal alloys through FJH technology for rapid heat treatment and structure optimization, and then synthesize them with carbon thermal shock technology to achieve higher performance and more excellent application effects.
Optimization and standardization of process parameters: In-depth study of the synergistic mechanism between FJH technology and Carbon Thermal Shock technology in the process of material preparation, and optimization of process parameters, such as heating temperature, heating time, current density, and so on. Establish a standardized process flow to ensure the stability and consistency of the material properties and provide a reliable technical guarantee for the commercial production and application of catalytic materials.
