Metallopolymers for catalytic generation of hydrogen
Metallopolymers composed of polymers and catalytically active diiron-disulfide ([2Fe-2S]) complexes are described herein. [FeFe]-hydrogenase mimics have been synthesized and used to initiate polymerization of various monomers to generate metallopolymers containing active [2Fe-2S] sites which serve as catalysts for a hydrogen evolution reaction (HER). Vinylic monomers with polar groups provided water solubility relevant for large scale hydrogen production, leveraging the supramolecular architecture to improve catalysis. Metallopolymeric electrocatalysts displayed high turnover frequency and low overpotential in aqueous media as well as aerobic stability. Metallopolymeric photocatalysts incorporated P3HT ligands to serve as a photosensitizer to promote photoinduced electron transfer to the active complex.
ELECTROLYTIC PROCESS FOR PREPARATION OF METAL CARBOXYLATE COMPLEXES
The invention relates to an electrolytic process for preparation of metal carboxylate complex comprising placing a semi-permeable membrane (18) between the electrodes in order to isolate the same. This membrane (18) prevents the migration of the metal ions from the anode to the cathode, thus increasing the metal ion concentration in the anolyte, leading to highly increased and faster formation of metal carboxylate complex.
Flame-retardant polyester fiber and its preparation method
A flame-retardant polyester fiber obtained by spinning flame-retardant polyester and irradiating with ultraviolet light and having a limiting oxygen index value of greater than 30.

Process for preparing alkali metal alkoxides in a three-chamber electrolysis cell
A process for electrochemical preparation of an alkali metal alkoxide solution is performed in an electrolysis cell having three chambers. The middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to cations, for example NaSICON, and from the anode chamber by a diffusion barrier, for example a membrane selective for cations or anions.
