- This innovative approach breaks the traditional use of heavy metal-based ferroelectric materials for water splitting, offering a cost-effective and high-production rate method for green hydrogen.
- The study, published in Advanced Functional Materials, demonstrates the potential of piezocatalytic technology in generating hydrogen from renewable sources.
Researchers from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bengaluru have developed a novel metal-free porous organic catalyst for the efficient production of hydrogen (H2) by harvesting mechanical energy. The team created a donor-acceptor-based covalent-organic framework (COF) that exhibits piezocatalytic activity for water splitting to produce H2. This innovative COF system uses a simple donor molecule (TAPA) and acceptor molecule (PDA) to create strong charge transfer properties, leading to the formation of dipoles that interact with mechanical pressure. The study showcases a new approach in catalytic technology by moving away from heavy metal-based materials to a more cost-effective and efficient system. The COF's unique electronic structure, with energy bands that resonate due to dipolar ordering, demonstrates its potential for green hydrogen production. By utilizing a metal-free system, the research opens up new possibilities for sustainable and high-rate hydrogen production.
