Piezocatalysis, a catalytic technology harnessing mechanical perturbations with piezoelectric materials for water splitting, has emerged as an environmentally friendly method for hydrogen production. In a groundbreaking development led by Prof Tapas K Maji in Bengaluru, a metal-free donor-acceptor COF has been created for piezocatalytic water splitting. This COF, utilizing imide linkages between organic donor and acceptor molecules, exhibits ferrielectric ordering, enhancing piezocatalytic activity. Traditionally, heavy metal-based materials were used for such purposes, but the COF's structure provides a higher charge density at pore surfaces, increasing efficiency. The porous nature of the COF facilitates water molecule diffusion for optimal catalysis, resulting in exceptional hydrogen production yields, surpassing traditional oxide-based catalysts. This advancement signifies a shift towards sustainable and efficient hydrogen production methods.
