An international team of scientists has developed an innovative catalytic technology that revolutionizes hydrogen production by eliminating direct CO₂ emissions. The process involves reacting hydrogen-rich bioethanol sourced sustainably from agricultural waste with water at a lower temperature of 270°C compared to traditional methods. This new approach, facilitated by a bimetallic catalyst, not only produces hydrogen but also generates high-value acetic acid, a versatile chemical used in various industries. The researchers from Peking University and Cardiff University highlight the significance of this breakthrough in advancing the green hydrogen economy and supporting global carbon neutrality goals. By co-producing hydrogen and acetic acid from biomass without releasing CO₂, the team establishes a circular economy model that reduces reliance on fossil fuels in the chemical industry. The technology's economic viability is further underlined by the industrial applications of acetic acid, making it a low-carbon alternative for sectors like acetate fibre manufacturing and pharmaceutical intermediates. This advancement marks a significant step towards achieving carbon-neutral hydrogen production and signifies a shift towards sustainable practices in the chemical industry. Published in the journal Science, the team's paper outlines the potential of their catalytic technology in contributing to a greener future and promoting a more sustainable approach to hydrogen production.
