Optimization of Mesoporous Carbon Adsorbents from Sucrose and Aerosil 380 Hydrophilic Silica by Hard Templating.

ABSTRACT: Mesoporous carbon materials were synthesized by using sucrose as a carbon source and hydrophilic Aerosil 380 as a hard template. A two-stage optimization process based on the response surface methodology using a central composite design (RSM-CCD) was employed to enhance the adsorption performance of the material for the crystal violet (CV) dye. The first stage of optimization yielded a maximum adsorption capacity of 155.4 mg g^-1 under carbonization conditions of 800 °C, 18.41 °C min^-1, and 60 min. Further, optimization of sucrose (23% m/V) and silica template (17.07% m/V) concentrations led to a significantly higher capacity of 223.5 mg g^-1. Characterization techniques confirmed the formation of amorphous graphitic structure (XRD), thermal decomposition of
