Novel metal-free catalysts were synthesized form maleic acid (MA) and citric acid (CA) based polymers for hydrogen generation form NaBH4. Surfactant-free-self-emulsion polymerization technique was used to synthesize poly(Maleic acid)(poly(MA)), poly(Citric acid)(poly(CA)) and poly(Maleic acid-co-Citric Acid) poly(MA-co-CA)) polymeric micro-particles in a single step. The prepared catalysts were characterized by zeta potential, SEM, FTIR and TGA. The hydrodynamic diameter of the poly(MA), poly(CA) and poly(MA-co-CA) micro-particles were found to be 0.681, 1.273, 1.604 mu m and the zeta potentia ...More
In this study, the poly (Castor Oil) (p(CO)) organo-particle from natural castor oil (CO) was synthesized for the first time in literature for sodium boron hydride (NaBH4) methanolysis hydrogen production. As is known, catalysts are used in most reactions performed in the chemical industry. Here, by analytical method, Fourier Transform Infrared Spectroscopy (FT-IR), Thermal Gravimetric Analyzer (TGA) and Ultra Field Emission Energy Dispersive Spectroscopy (SEM) analyzes of the catalyst were performed and the characteristics of the catalyst were determined. Also for the methanolysis of the p(CO ...More
The use of the metal free catalysts synthesized form natural and environmental friendly materials for fast generation of hydrogen is accomplished form sodium borohydride (NaBH4) 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 conti ...More
