Abstract

Mesoporous carbon has been synthesized using soft-template method with phloroglucinol as carbon precursor and pluronic F127 as a template to form mesosize pores in carbon structure. The Brunauer-Emmett-Teller (BET) results prove the existence of hysteresis loop and adsorption isotherm type IV with total surface area of 432.498 m2/g and pore diameter of 7.46 nm. The mesoporous carbon was then impregnated with various amount of nickel metal using Ni(NO3)2 as precursor, followed by four ways of reduction: (1) with ethylene glycol in aqueous solution; (2) with ethylene glycol in 98 % ethanol in water; (3) with NaBH4; and (4) with H2 gas. Energy Dispersive X-Ray (EDX) analysis shows that nickel content in materials after reduction were (1) 34.48 %, (2) 0.02 %, (3) 0.9 % and (4) 1.73 %, in respective to the reduction methods. X-Ray Diffraction (XRD) patterns of mesoporous carbon reduced with NaBH4 and H2 show no change in mesoporous carbon structure, especially for peak at 2θ of 24.44° and 43.18°. After impregnation, the materials were further tested for their catalytic activity for acetylene reactions with CO2. The reactions were conducted in a 100 mL batch reactor with a pressure ratio of acetylene to CO2 of 0.2:0.8. Some reaction conditions were examined to determine the effect on the reaction: reaction time (3, 6, 12) h and reaction temperature (25, 40 and 80) °C. Product analysis using High Performance Liquid Chromatography (HPLC) shows that new peak appears at retention time of 3.625 minutes. The optimum condition was obtained at 25 °C and 3 hours.
