| Abstract |
E-waste has become one of fastest growing waste streams globally. The conversion of e-waste into a valuable nanomaterial is an efficient and sustainable approach toward developing a circular economy. In this study, MCM-48 mesoporous silicas were synthesized from recycled electronic packaging resin waste. Next, ordered mesoporous carbons were synthesized using the MCM-48 template. The influence of synthesis variables, such as the surfactant premixing procedure, cationic surfactant type, isothermal or non isothermal pyrolysis procedure, pyrolysis time, carbon precursor, and the pre-and post-treatment procedures of samples on the surface properties of carbon materials was investigated. Experimental results confirmed that well-ordered CMK-1 materials with a high purity of 99.94 wt % were successfully synthesized using the resin waste as a silica template source. The resulting mesoporous carbon had a large surface area of 1715 m(2)/g, a pore volume of 1.02 cm(3)/g, and a uniform bimodal pore size of 2.33 and 3.86 nm. The carbon structure was sensitive to the pyrolysis temperature, pyrolysis time, and the concentration of sulfuric and hydrofluoric acid. The recycling of e-waste into MCM-48 and CMK-1 materials can reduce environmental pollution as well as achieve economic and social benefit. |
