Novel Graphene Oxide–Confined Nanospace Directed Synthesis of Glucose-Based Porous Carbon Nanosheets with Enhanced Adsorption Performance
Glucose-based
porous carbon nanosheets (GPCNS) were synthesized by an integrated
graphene oxide–confined nanospace directed KOH-activated process
and were applied as adsorbent for efficient removal of sulfamethazine
(SMZ). The effects of GO dosage on the structure, specific surface
area, and adsorption capacity of GPCNS-<i>x</i> were investigated.
The highest SMZ uptake of 820.27 mg g<sup>–1</sup> (298 K)
was achieved in glucose-based porous carbon nanosheets inherited from
using 1% GO relative to glucose (GPCNS-1). Also, the adsorption isotherms,
thermodynamics, and kinetics of SMZ onto GPCNS-1 were studied in detail.
In addition, the effects of ionic strength and solution pH on the
adsorption capacity of GPCNS-1 were also investigated, indicating
good environmental tolerance of GPCNS-1. Furthermore, regeneration
experiments showed that GPCNS-1 has good reproducibility and durability.
We believe that these graphene oxide–confined nanospace directed
KOH-activated process biomass-based carbon nanosheets are highly promising
as absorbents in the field of environmental protection
