  • Patent Published for Revolutionary Electrode Material in Clean Hydrogen Production June 19, 2025

    In the growing need for clean energy solutions, Dr Sabyasachi Chakrabortty, Associate Professor, Department of Chemistry, Dr Uday Kumar Ghorui (Post Doctoral Scholar) and Mr Gokul Sivaguru (PhD scholar) have filed and published the invention of “Electrode material” with Application Number: “202441075507” in the Patent Office Journal, on developing a low-cost, eco-friendly electrode material using a simple hydrothermal process. The research team has developed a pioneering Ternary Transition Metal Oxide (TTMO) nanocomposite electrode for the hydrogen evolution reaction (HER). Their work focuses on creating a sustainable alternative to fossil fuel-based hydrogen production methods, which currently generate significant CO₂ emissions.

    Abstract

    This disclosure focuses on developing a low-cost, earth-abundant Ternary Transition Metal Oxide (TTMO) nanocomposite electrode for efficient, clean hydrogen production, addressing the depletion of fossil fuels and the CO₂ emissions from current methods like methane reforming and coal gasification. Using a simple hydrothermal process, the TTMO electrode demonstrates excellent electrochemical HER performance, with low overpotential and 100-hour stability, despite challenges in cost, infrastructure, and safety for hydrogen energy generation.

  • Synthesising Copper-based Particles to Recycle Industrial Mineral Waste into Useful Products May 29, 2025

    In an attempt to recycle industrial mineral waste into useful products, Dr Jaidev Kaushik from the Department of Chemistry has worked on synthesising copper-based particles that use light to convert carbonate-rich materials like marble dust into acetic acid, a valuable chemical used in industry and fuel production. He has published his research in a paper titled “Photocatalytic Upcycling of Marble Waste into Acetic Acid” in the prestigious Journal of Materials Chemistry A, having an impact factor of 10.7.

    The particles drive the reaction efficiently by illuminating the green light on a mixture of the material and hydrogen peroxide solution. He has also tested the method on other carbonate wastes like chalk dust and scale, showing its potential for recycling industrial mineral waste into useful products.

    Abstract

    In this study, disk-shaped copper sulfide nanoparticles (CuS-NPs) were synthesised via a simple co-precipitation method and used as a photocatalyst for the reduction of carbonate species derived from marble dust into acetic acid (AcOH), an important industrial and biofuel precursor. The photocatalytic reaction was carried out under monochromatic light (525 nm) in a hydrogen peroxide–water mixture, which served as an electron and radical-rich medium. Key parameters such as solvent composition, light source, catalyst concentration and reaction time were optimised to get the maximum yield of AcOH. The reaction mechanism was investigated using radical scavenging experiments. The practical applicability of the approach was further tested on two additional real-life carbonate waste materials, i.e. chalk dust and scale.

    Practical Implementation/ Social Implications of the Research

    This research offers a sustainable method to convert carbonate-rich industrial wastes like marble dust, chalk dust, and scale into acetic acid, which is widely used in the chemical, pharmaceutical, and biofuel industries. By using light-driven reactions with safe, low-cost materials, the process reduces environmental pollution, supports waste valorisation, and contributes to a circular economy. It can be implemented in industries that generate carbonate waste, promoting green chemistry and lowering dependence on fossil-based raw materials.
