In Beijing, a team of international scientists, spearheaded by Peking University, has introduced a pioneering method for hydrogen production that eliminates direct carbon dioxide emissions. Traditional techniques of hydrogen production typically involve high temperatures and significant CO2 emissions. However, this new approach utilizes a bimetallic catalyst to produce hydrogen from bioethanol and water at a much lower temperature, offering an eco-friendly and economically feasible solution. The study, published in Science, highlights the potential of this method in advancing the green hydrogen economy and meeting global carbon neutrality targets. Moreover, the co-production of acetic acid adds further economic value to the process. Collaborating with researchers from various institutes, the team envisions their technology as a crucial advancement towards sustainable hydrogen production and a cleaner future.
