Joule heating catalysis

<p indent="0mm">With the rapid development of renewable energy generation technology, the use of green power supply to produce high-value chemicals and fuels has become an important way of large-scale energy storage and clean and low-carbon development, which is expected to provide a new solution to promoting the transformation of the national energy structure and achieving the carbon peaking and carbon neutrality goals. Among them, the direct presenting of heat for chemical reaction using Joule heating generated by the current flowing through the catalyst has many advantages in strengthening heat transfer and improving performance. It has begun to be reported in the field of energy and environmental catalysis, such as reforming, dehydrogenation and degradation reaction. It is a new direction of cross-fusion in the fields of chemistry, physics and materials, and is becoming the forefront of international scientific research. However, the mechanism of Joule heating, matched catalyst design and controlled chemicals synthesis are still not well understood. In order to further promote the understanding and in-depth study, this work tries to put forward the concept of ″Joule heating catalysis″ and explain its basic principle, scientific connotation and action mechanism. On this basis, the application scenarios and future development opportunities and challenges of Joule heating catalysis are discussed.
