Promoting Hydrogen Evolution of g-C3N4 Based Photocatalyst by Indium and Phosphorus Co-doping

Indium and phosphorus co-doped g-C3N4 photocatalyst (In,P-g-C3N4) was prepared by K2HPO4 post-treatment of indium doped g-C3N4 photocatalyst (In-g-C3N4) derived from in-situ copolymerization of dicyandiamide and indium chloride. The experimental results...

Flame-retardant and crease-proofing finishing of cotton fabrics via in-situ copolymerization of ethylene phytic acid and itaconic acid, part I: Fabrication process

Ethylene phytic acid (PA) and unsaturated itaconic acid (IA) could be copolymerized in-situ and cross-linked on the cotton fabrics to enhance flame-retardant and crease-proofing properties. Natural phytic acid was modified with glycidyl methacrylate (GMA) and characterized by IR ,1HNMR and TG. The IR Indicated that new characteristic absorption peaks appear near 1720, 1470, 1380, and 1002 cm-1 for the molar ratios PA: GMA of 1:3 or 1:6, the peaks correspond to the bending vibration of C=O, C-H, CH3, and C=O-O respectively in the GMA. The 1HNMR results further confirmed the reaction between GMA and PA, and the TG results revealed the thermal properties of PA .

NITRILE COMPLEXES AS EFFECTIVE ANTIMICROBIAL ADDITIVES

Antimicrobial properties of nitrile complexes of transition metal salts were studied including the investigation of their activity in surfactants and mineral oil environments. Experiments of the polymeric complexes preparation by in-situ copolymerization of the nitrile polymers in the presence of transition metal salts and reactions of transition metal salts added to the ready polymers were performed. The dependence of the polymer complexes forming particularities on central metal atoms nature was determined.
