Carbon dioxide (CO2) and methane (CH4) account for over 90% of the total greenhouse gas emissions in CO2 equivalent, making them driving factors for global warming and consequently for shaping current environmental policies. To meet environmental targets, society needs to concurrently emit less and capture more greenhouse gases. Dry reforming of methane (DRM), where CO2 and CH4 are converted into H2 and CO (syngas), is a commercially attractive way to produce syngas from abundant feedstock including industrial and agricultural waste while capturing harmful greenhouse gases. However, in the case of DRM, conventional methods relying on thermally driven catalysis suffer from high energy requirements which render the reaction costly and environmentally unsustainable. Here, we propose to use a sunlight-assisted approach to drive the reaction at substantially lower temperatures. Mg has been recently discovered as a sustainable plasmonic metal with the best match to the solar spectrum. Our recent work pioneered catalytically active plasmonic nanoparticles based on cheap and earth-abundant Mg and demonstrated their excellent light-enhanced catalytic performance, making Mg an ideal candidate for application in sunlight-assisted low-temperature DRM.The objective of this proposal is to explore the pathway from ground-breaking research on Mg-based catalytically active plasmonic nanoparticles towards commercially viable innovation in low temperature gas-phase transformation of stable molecules, using DRM as the model reaction. To achieve this ambitious goal, this project will advance the technical understanding and capabilities that will underpin the target market, develop our business strategy, and forge links with industrial partners. The outcomes will set the path towards commercial scale, sustainable, low-cost and low-emission conversion of greenhouse gases into high value-added chemical building blocks.

二氧化碳 (CO2) 和甲烷 (CH4) 占二氧化碳当量温室气体排放总量的 90% 以上，使其成为全球变暖的驱动因素，从而影响当前环境政策的制定。为了实现环境目标，社会需要同时减少排放并捕获更多温室气体。甲烷干重整 (DRM) 将 CO2 和 CH4 转化为 H2 和 CO（合成气），是一种具有商业吸引力的方法，可以利用丰富的原料（包括工业和农业废物）生产合成气，同时捕获有害的温室气体。然而，就 DRM 而言，依赖热驱动催化的传统方法存在高能量需求，这使得反应成本高昂且环境不可持续。在这里，我们建议使用阳光辅助的方法在大幅降低的温度下驱动反应。最近发现镁是一种可持续的等离子体金属，与太阳光谱最匹配。我们最近的工作首创了基于廉价且地球丰富的镁的催化活性等离子体纳米颗粒，并展示了其优异的光增强催化性能，使镁成为阳光辅助低温DRM应用的理想候选者。本提案的目的是探索使用 DRM 作为模型反应，从镁基催化活性等离子体纳米颗粒的突破性研究到稳定分子低温气相转变商业上可行的创新的途径。为了实现这一雄心勃勃的目标，该项目将提高技术理解和能力，以支持目标市场、制定我们的业务战略并与工业合作伙伴建立联系。其成果将为将温室气体以商业规模、可持续、低成本和低排放转化为高附加值化学构件铺平道路。
