This research study carbon activation prepared from Bagasse, a waste of sugar factory. The activation was conducted in water vapor at 600°C (C600) and 700 °C (C700). The activated carbon was then tested for water vapor adsorption. The produced-carbon has diffraction peak at 2θ of 25°, with surface area are 584.940 m²/g and 533.301 m²/g for C600 and C700, respectively. C600 also shows higher water vapor adsorption than C700, the value is 0.223 g/g. It shows a potency of Bagasse waste as raw material for adsorbent powder.

“…Besides this, the large porous framework of carbon in the Au/OMC catalyst with the Au NPs anchored on the surface of carbon provides accessible routes for the diffusion of charge and electrolyte which may also favor the electro-oxidation process. 36 The effects of change of the scan rates during the methanol oxidation process are shown in Figure 8a. It is clearly seen that the peak current increases with the increase of the scan rate and the peak current linearly increases with the square root of the scan rate (Figure 8b) which indicates that the electron transfer is reversible in terms of the diffusion layer thickness.…”

Ordered mesoporous carbon-supported gold nanoparticles (Au/OMC) have been fabricated in one step through a hard template method using gold nanoparticle-intercalated mesoporous silica (GMS) to explore two different catalytic properties, for example, electrocatalytic oxidation of methanol and colorimetric determination of glutathione (GSH). The catalytically inert but conducting nature of mesoporous carbon (OMC) and promising catalytic activity of gold nanoparticles (AuNPs) has inspired us to synthesize Au/OMC. The as-prepared Au/OMC catalyst was characterized by powder X-ray diffraction, N2 adsorption–desorption, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray analysis-elemental mapping, and X-ray photoelectron spectroscopy. The characterization results indicate that AuNPs are uniformly distributed on the surface of OMC. The conducting-OMC framework with a high surface area of Au/OMC provides superior transport of electrons through the porous surface of carbon matrix and resulted in its high efficiency and stability as an electrocatalyst for the oxidation of methanol in comparison to CMK-3, SBA-15, and GMS in alkaline medium. The efficiency of Au/OMC toward methanol oxidation in alkaline medium is much higher in comparison to that in acidic medium. The lower value of If/Ib in the acidic medium in comparison to that in the alkaline medium clearly indicates that the oxidation process with Au/OMC as a catalyst is much more superior in alkaline medium with better tolerance toward the accumulation of intermediate CO species on the active surface area. Furthermore, the Au/OMC catalyst is successfully utilized for the detection and quantification of GSH spectrophotometrically with a limit of detection value of 0.604 nM.

“…If combined with other modification methods, a new modified material with better adsorption ability would be achieved. Moreover, the large surface area of carbon materials could improve the properties of batteries [38] and increase hydrogen storage capacity [39], so the liquid nitrogen treatment method for carbon material modification may have broader application prospect in sewage treatment and industrial manufacture.…”

Antibiotic residues in the aquatic environment have become a global problem posing a serious threat to the environment and an inherent health risk to human beings. In this study, experiments were carried to investigate the use of carbon material modified by liquid nitrogen treatment (CM1) and carbon material unmodified by liquid nitrogen treatment (CM2) as adsorbents for the removal of the antibiotic ampicillin from aqueous solutions. The properties of the CMs (CM1 and CM2) and the effects of variations of the key operating parameters on the removal process were examined, and kinetic, isothermal and thermodynamic experimental data were studied. The results showed that CM1 had larger specific surface area and pore size than CM2. The ampicillin adsorption was more effective on CM1 than that on CM2, and the maximum adsorption capacity of ampicillin onto CM1 and CM2 was 206.002 and 178.423 mg/g, respectively. The kinetic data revealed that the pesudo-second order model was more suitable for the fitting of the experimental kinetic data and the isothermal data indicated that the Langmuir model was successfully correlated with the data. The adsorption of ampicillin was a spontaneous reaction dominated by thermodynamics. In synthetic wastewater, CM1 and CM2 showed different removal rates for ampicillin: 92.31% and 86.56%, respectively. For an adsorption-based approach, carbon material obtained by the liquid nitrogen treatment method has a stronger adsorption capacity, faster adsorption, and was non-toxic, therefore, it could be a promising adsorbent, with promising prospects in environmental pollution remediation applications.
