The effect of temperature on preparation of nano material via dopping ZP in mesoporous activated carbon

摘要

A nano material was obtained by dopping ZP in mesoporous nanocarbon which prepared by physical activation carbon via thermal effect .A series of ZP materials dopped in activated carbon obtained from DP by physical activation. The dopped ZP-C materials were heat-treated at various temperatures, 100–800 0 C. TGA & DTG thermal analysis showed that incorporation of the doping agent within the carbon DP layered materials which enhanced the heat-resistivity of the nanohybrid materials in the thermal decomposition pathway. Porous carbon materials can be obtained from the heat-treatment of the nanohybrids at 700 and 900 0 C. Calcination of the dopped material was achieved at 900 0 C under nitrogen atmosphere which produces mesoporous and high pore volume carbon materials. According to the kinetics of Freeman–Carroll and Coats–Redfern the calculated order of reaction of ZP in DP is 2. The calculated activation energy of both matrices are 402 and 350 kJ mol –1 .
