Abstract: Abstract Methane dry reforming not only utilizes two potent greenhouse gases of methane and carbon dioxide, but also provides a valuable feedstock for the production of chemicals. However, this process has been heavily hindered by high operating temperature and coke formation with catalyst deactivation over the last century. Herein, we propose an approach whereby concentrated-solar catalytic methane dry reforming addresses these longstanding issues. By leveraging focused light as the sole energy source and utilizing a well-designed catalyst, the catalyst with Ni-O4 coordination active center achieves high conversion rates of 93.6% for CH4 and 93.7% for CO2, meanwhile sustaining stability for over 800 hours. Particularly noteworthy is the light-to-chemical energy conversion efficiency reaching 25.9%. This research represents a significant leap forward in integrating renewable energy sources with chemical production, offering a viable and sustainable alternative to traditional thermochemical processes for generating valuable chemicals.
