Activated carbon derived from mango leaves as an enhanced microwave absorbing material

Excellent microwave absorbing performance of biomass-derived activated carbon decorated with in situ-grown CoFe2O4 nanoparticles

“…The waste mango leaves collected from the institute premises were used as biomass, which was then carbonized and activated (using KOH) to obtain activated carbon. The detailed synthesis process has already been reported 20 . The cobalt ferrite (CoFe 2 O 4 )/Activated carbon composite was prepared by hydrothermal method 29,30 .…”

“…In recent years activated carbon derived from biomass has shown its potential as an efficient dielectric loss material 8,[18][19][20] . The nanopores and micro pores present in the biomass based activated carbon provide a blend of solid and air, thus, the material behave as an effective medium, which facilitates better impedance matching 18,21 .…”

“…5,8 In recent years, activated carbon derived from biomass has shown potential as an efficient dielectric loss material. 8,[18][19][20] The nanopores and micropores present in biomass-based activated carbon provide a blend of solid and air; thus, the material behaves as an effective medium that can facilitate better impedance matching. 18,21 Furthermore, its low density, high thermal stability, facile synthesis process and low cost make it an excellent choice for MW absorption applications.…”

“…These results suggest the potential of activated carbon/magnetic material based composites as MW absorbing material. Recently, we had also reported the potential of waste mango leaf biomass based activated carbon (AC) as an excellent MW absorber20 . When this AC was made composite with another dielectric material i.e.…”

Development of Graphene Quantum Dots by Valorizing the Bioresources – A Critical Review

“…Mango leaves are readily available bioresources with À OH, À COOH, À C=O, amino, and nitro groups. Mango leaves are readily available, cost-effective, and abundant [39] (Negi P et al, 2021).…”
