Abstract

In this review paper, the recent development on the adsorption of organic dyes by metal-doped porous carbon materials were reviewed. The primary objective of this paper is to sort out the dispersion information of metal-doped porous carbon materials widely used in organic dye adsorption. Various metal-doped porous carbon materials adsorbing organic dyes are summarized and discussed here for the first time. Key factors affecting the adsorption process such as the amount of doped metal, solution pH, and temperature are also reported and discussed. The adsorption mechanisms such as electrostatic interaction, π-π interaction, hydrogen bonding and synergistic interaction between metal particles and carbon materials are proposed for organic dyes adsorption on metal-doped porous carbon with the help of related works from the literature. Finally, few suggestions for future studies on metal-doped porous carbon materials are proposed.
