摘　　要：随着可再生能源发电技术的迅速发展,利用绿电供能生产高值化学品和燃料成为大规模储能和推进清洁低碳发展的重要途径,有望为促进国家能源结构转型和实现“双碳”目标提供全新解决方案.利用电流流经催化剂产生的焦耳热对化学反应直接供热,具有强化传热和提高性能等诸多优势,其在重整、脱氢、降解等能源和环境催化领域开始有报道,是化工、物理和材料等领域交叉融合的新方向,正在成为国际科学研究前沿,但对焦耳热作用机制、相匹配催化剂设计及化学品可控合成等理解仍存在不足.为进一步深化认识并推进相关领域的深入研究,本文尝试提出“焦耳热催化”概念,阐释其基本原理、科学内涵及作用机制.在此基础上,探讨焦耳热催化的应用场景及未来发展的机遇与挑战.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 lowcarbon 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 crossfusion 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.
