♦ Indian researchers have developed a novel, cost-effective, metal-free catalyst that can efficiently produce hydrogen fuel by harvesting mechanical energy.

♦ This innovation represents a major breakthrough in green hydrogen technology and offers a promising path toward cleaner alternatives to fossil fuels.

♦ Unlike traditional catalysts that rely heavily on metal-based ferroelectric materials, the new COF system is entirely organic and metal-free.

♦ It is composed of tris(4-aminophenyl)amine (TAPA) as the donor molecule and pyromellitic dianhydride (PDA) as the acceptor.

♦ These materials form imide linkages that give rise to a unique structural phenomenon known as ferrielectric (FiE) ordering.
