Hierarchical Porous Carbon Nanospheres for Efficient Removal of Toxic
Organic Water Contaminants of Phenol and Methylene Blue
Posted on 2018-01-16 - 19:18
Hierarchical porous
carbon nanospheres were synthesized by a hydrothermal
process at 130 °C/24 h using different triblock copolymers such
as F108 (PEO133PPO50PEO133; PEO,
poly(ethylene oxide); PPO, poly(propylene oxide)), F127 (PEO106PPO70PEO106), and L64 (PEO13PPO30PEO13) as soft templating agents. Characterization
of the samples was carried out by low angle XRD, Raman spectra, FESEM,
TEM, and N2 adsorption–desorption studies. The BET
surface area of the samples was in the range 600–750 m2/g comprised of micropores and mesopores. Nanospherical particles
of size range 60–100 nm were formed. The synthesized samples
were used for the removal of phenol and methylene blue (MB), the toxic
organic contaminant in water. The maximum adsorptions of 98.9 and
100% were observed within 10 min for phenol and MB, respectively.
For different soft templates, the adsorption capacity of the samples
followed in the order CF108 > CF127 > CL64, which was affected
by
the textural properties of the corresponding samples. Selective adsorption
of the samples was also studied in the presence of both pollutants,
phenol and MB.
