- The strategy not only produces H2O2 efficiently but also can help degrade industrial pollutants like toxic dyes.
- By controlling the oxygen reduction process through specific catalysts, the researchers can generate H2O2 instead of water, making the method sustainable and energy-efficient.
- The innovative approach is believed to be scalable and could have applications beyond H2O2 production, such as generating electricity in remote areas.
Researchers at the Indian Institute of Science (IISc) have devised a novel approach for producing Hydrogen Peroxide (H2O2) on-site, addressing the costly and energy-intensive industrial methods. By leveraging a zinc-air battery, oxygen reduction reactions lead to the generation of H2O2, offering a sustainable and low-cost alternative. The research team, led by Prof. Aninda J. Bhattacharyya, utilized zinc as the anode and ambient air as the cathode in the metal-air battery system. Through precise control of the oxygen reduction process using metal-free catalysts based on carbon, the team managed to steer the reaction towards H2O2 formation rather than water. This breakthrough not only makes H2O2 production more efficient but also enables the degradation of pollutants like toxic dyes. Prof. Bhattacharyya emphasized the scalability and potential applications of this method, highlighting its energy efficiency and sustainability. The study, led by Asutosh Behera, a PhD student at SSCU, signifies a significant step towards environmentally friendly and cost-effective H2O2 production that could find utility in various sectors beyond chemicals.
