MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202441020616 A) filed by Jawaharlal Nehru Centre For Advanced Scientific Research, Bangalore, Karnataka, on March 19, 2024, for 'piezocatalytic covalent organic framework for hydrogen production by splitting water.'
Inventor(s) include Maji, Tapas Kumar; Ghosh, Adrija; and Biswas, Sandip.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a method for splitting water, the method comprising: contacting water with a mechanically stressed catalyst to produce oxygen and hydrogen, wherein the mechanically stressed catalyst is obtained by subjecting a non-centrosymmetric covalent-organic framework (COF) to ultrasonic radiation. The present disclosure further provides a non-centrosymmetric covalent- 10 organic framework (COF) as a piezocatalyst for piezoelectric splitting of water, the COF comprises a donor molecule selected from tris(4-aminophenyl)amine, 1,3,5- tris-(4-aminophenyl)triazine, N,N-bis(4'-amino-[1,1'-biphenyl]-4-yl-[1,1'- biphenyl]-4,4'diamine, 4',4",4"'-1,3,5-tris-(2,4,6-triyl)tris(([1,1'-biphenyl]-4- amine)) or 5"-(4'-amino-[1,1'biphenyl]-4yl)[1,1':4',1",1"':4'",1""- 15 quinquephenyl]-4,4""-diamine; and an acceptor molecule selected from substituted or unsubstituted pyromellitic dianhydride, perylene dianhydride, or naphthalene dianhydride."
