Strategy for optimizing the synthesis and characterization of activated carbons obtained by chemical activation of coffee husk

Abstract

The present work aims on the one hand to optimize the main influencing factors in the synthesis of activated carbon obtained from coffee husk as a widely available lignocellulosic precursor,...

Synthesis and characterization of peanut shell-derived ferromagnetic activated carbon: application in the Fenton process for the degradation of methyl orange

“…Subsequently, the hydrothermal method was used for the precipitation of iron oxide into the activated carbon matrix. The development of activated carbons functionalized with active iron oxide phases for the Fenton reaction is a promising way to obtain new multifunctional porous materials combining adsorption and advanced oxidation, allowing the development of an efficient, economical, and environmentally friendly treatment process (Joshi et al, 2012;Ngueabouo et al, 2022). The control of the properties of the host material is important to optimize the functionality of the composite catalyst.…”

Adsorption and desorption of flavonoids on activated carbon impregnated with different metal ions

“… 1 Commonly used powdered AC has high mechanical strength and good mechanical and chemical stability. 2 Activated carbon has a wide range of biomass sources, such as coffee husk, 3 shea residue, 4 avocado seeds 5 and straws; the biomass can also be prepared as a graphene material to catalyze the production of biodiesel from microalgae lipids under solar energy. 6 Therefore, it is widely used in adsorption, separation, catalysis, medicine and other fields.…”
