Sustainable fuels are within reach but processes need to be optimized for low-cost industrial scale production. Converting hydrogen and carbon dioxide into methanol for sustainable fuel is one route, but the reaction pathway needs elucidating and catalysts optimizing. A team of researchers from Khalifa University has developed a model to do just that.   Transforming carbon dioxide emissions into value-added products like methanol for fuel is essential for the development of a circular economy and reducing anthropogenic impact on the atmosphere. But the process of developing these products can introduce side reactions that can significantly influence efficiency and the quality…
