Effect of heat treatment on the characteristics of electroless activated carbon-nickel oxide nanocomposites

Over the years,different experimental techniques have been employed to prepared activated carbon-metal oxide composite materials. however,some of these methods entail cutting-edge equipment and long processing time which may result in the destruction of the carbon structure. electroless plating,which is a simple and efficient method,have been used to deposit nickel oxide nanoparticles on activated carbon prepared from oil palm shell (ops) using microwave -assisted co2 activation. the nanocomposites have been heated at various temperatures (300,400 and 500 °c) for 1 and 2 h. the prepared activated carbon has bet surface area and total pore volume of 574.37 m2 g-1 and 0.244 cm3 g-1,respectively. the optimum heat treatment temperature has been found to be 400 oc. also,the weight percent composition of nickel has been shown to increase with increase in treatment time. © 2017 penerbit utm press. all rights reserved.
