Synthesis of Poly(ginger oil) organo Particles as a Metal Free Catalysis and Their Use in Hydrogen Production from Sodium Borohydride Methanolysis

摘要

The use of the metal free catalysts synthesized form natural and environmental friendly materials for fast generation of hydrogen is accomplished form sodium borohydride (NaBH_4) methanolysis assays. Thus, green and metal free-catalysts were prepared form natural resources of ginger oil (GO). Polymeric GO particles were synthesized via emulsion polymerization technique and characterized in detail. The hydrodynamic diameters of p(GO) particles were found to be in the 220 nm and the zeta potential was - 162.48 mV. TGA results showed that thermal decomposition of microparticles was gradually continuing up to 700 ℃. The catalytic performance of the metal-free p(GO) particles were studied under various conditions such as changing NaBH_4 concentrations, amount of p(GO) and media temperature. A fast hydrogen production rate of 617.8 mL min~(-1) gcat~(-1) is achieved at 20 ℃ by methanolysis of 50 mM NaBH_4 and 0.1 g p(GO) particles. Factors are regularly investigated to reveal methanolysis kinetic properties. The activation energy is found 24 ±0.9 kJ mol~(-1). Thanks to this study, the p(GO) particle obtained from GO has been transformed into a product with high energy value.
