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）占相当于CO2的温室气体排放量的90％以上，使其成为全球变暖的驱动因素，因此构成了当前的环境政策。为了满足环境目标，社会需要同时发射较少并捕获更多的温室气体。甲烷（DRM）的干燥改革，其中二氧化碳和CH4转化为H2和CO（Syngas），是一种在捕获有害温室气体的同时，在包括工业和农业废物在内的丰富原料中生产合成器的一种商业吸引力的方式。但是，在DRM的情况下，依赖热驱动催化的常规方法遭受了高能量需求，这使得反应昂贵且环境不可持续。在这里，我们建议使用阳光辅助方法在大大较低的温度下驱动反应。最近发现MG是一种可持续的等离子金属，与太阳能光谱匹配最佳。我们最近的工作基于廉价和土壤丰富的毫克开创了催化活跃的等离子纳米颗粒，并证明了它们出色的光线增强催化性能，使MG成为在阳光辅助低体温下施用的理想候选者。使用DRM作为模型反应，稳定分子的气相转化。为了实现这一雄心勃勃的目标，该项目将提高目标市场，制定我们的业务战略并与工业合作伙伴建立联系的技术理解和能力。结果将为商业规模，可持续性，低成本和低排放气体转化为高增值化学构建块。
