Sunlight-powered conversion of greenhouse gases into valuable chemicals
Researchers at McGill University have developed a groundbreaking process that uses sunlight to convert harmful greenhouse gases into valuable chemicals, offering a sustainable solution to combat climate change and support eco-friendly industrial production.
By harnessing the power of sunlight, the research team has successfully transformed methane and carbon dioxide into green methanol and carbon monoxide in a single reaction. Both of these products are highly sought after in the chemical and energy industries.
The process is inspired by nature’s own mechanism of photosynthesis, where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. In this case, a catalyst consisting of gold, palladium, and gallium nitride initiates a reaction when exposed to sunlight, resulting in the production of green methanol from carbon dioxide and methane, with carbon monoxide as a byproduct.
Unlike traditional chemical reactions that require high heat and harsh chemicals, this innovative approach operates at room temperature, making it more environmentally friendly. The research team believes that this discovery could contribute significantly to achieving Canada’s goal of net-zero emissions by 2050.
Funding for the study was provided by various organizations, including the Natural Sciences and Engineering Research Council of Canada, the Canada Research Chair program, and McGill University’s research funds.
