Atmospheric CO concentrations keep increasing at intensifying rates due to rising energy and material demands. The chemical production industry is a large energy consumer, responsible for up to 935 Mt of CO emissions per year, and decarbonization is its major goal moving forward. One of the primary sources of energy consumption and CO emissions in the chemical sector is associated with the production and use of heat for material synthesis, which conventionally was generated through the combustion of fossil fuels. To address this grand challenge, Joule heating has emerged as an alternative heating method that greatly increases process efficiency, reducing both energy consumption and greenhouse gas emissions. In this Review, we discuss the key concepts that govern these Joule heating processes including material selection and reactor design, as well as the current state-of-the-art in the literature for employing these processes to synthesize commodity chemicals along with advanced materials such as graphene, metal species, and metal carbides. Finally, we provide a perspective on future research avenues within this field, which can facilitate the widespread adoption of Joule heating for decarbonizing industrial processes.
由于能源和材料需求不断增加，大气中的一氧化碳（CO）浓度正以越来越快的速度持续上升。化工业是能源消耗大户，每年的CO排放量高达9.35亿吨，脱碳是其未来的主要目标。化工领域能源消耗和CO排放的主要来源之一与材料合成过程中热量的产生和使用有关，传统上这些热量是通过化石燃料燃烧产生的。为应对这一重大挑战，焦耳热已成为一种替代加热方法，可大幅提高工艺效率，减少能源消耗和温室气体排放。在本综述中，我们讨论了控制这些焦耳热过程的关键概念，包括材料选择和反应器设计，以及文献中利用这些过程合成商品化学品以及石墨烯、金属物种和金属碳化物等先进材料的当前技术水平。最后，我们对该领域未来的研究方向提出了展望，这有助于推动焦耳热在工业过程脱碳中的广泛应用。
