Indian scientists have developed a novel metal-free catalyst for hydrogen production, marking a major advancement in sustainable energy and green hydrogen technology.
About the Metal free Catalyst
- The catalyst is a donor–acceptor based Covalent Organic Framework (COF) composed of Tris(4-aminophenyl)amine (TAPA) and Pyromellitic Dianhydride (PDA), forming Ferrielectric (FiE) order for high piezocatalytic efficiency.
- Piezocatalytic efficiency refers to how effectively a material can convert mechanical energy (such as pressure, vibration, or stretching) into chemical energy.
- Working Mechanism: It enables water splitting through mechanical energy harvesting, converting ambient pressure or vibrations into hydrogen fuel via electron-hole generation.
Benefits of the Metal free technology
- Unlike traditional metal-based systems, this COF is entirely organic, cost-effective, and metal-free, reducing environmental impact and manufacturing costs.
- The porous, sponge-like architecture allows efficient water diffusion and charge accumulation at the pore surfaces, enhancing hydrogen output.
Significance of the Technology
- This innovation offers a clean, scalable alternative to metal-based hydrogen production, aligning with India’s National Green Hydrogen Mission.
- Theoretical models confirm its dynamic electronic structure enables effective catalysis under mechanical pressure.
- The breakthrough provides a viable route to utilize ambient mechanical energy for green hydrogen generation, advancing India’s leadership in renewable energy.
