Synergistic Effect of Chitosan and Activated Carbon (AC) in Suppressing Recombination Charge of Composite Ca2Fe2O5−AC/Chitosan for High Photodegradation of Fipronil Wastewater

Nickel Slag/Laterite Soil and Nickel Slag/Iron Sand Nanocomposites: Structural, Optical, and Electromagnetic Absorption Properties

“…In ref , the calculated crystallite size can also be included, and the stacking fault of the nanocomposite can also be predicted using the W–H method. The aforementioned method has been successfully used to obtain our previously reported results for CuO/C, Fe 3 O 4 /C, and Ca 2 Fe 2 O 5 –AC/chitosan . In determining the structural parameters using XRD, if the diffraction peaks of the nanocomposites are assumed to be isotropic, then the SSP method can be applied to calculate the size–strain parameters.…”

“…The aforementioned method has been successfully used to obtain our previously reported results for CuO/C, 35 Fe 3 O 4 /C, 67 and Ca 2 Fe 2 O 5 –AC/chitosan. 70 In determining the structural parameters using XRD, if the diffraction peaks of the nanocomposites are assumed to be isotropic, then the SSP method can be applied to calculate the size–strain parameters. In this method, the strain profile is denoted by a Gaussian function and the crystallite size is denoted by a Lorentzian function.…”

In situ construction of oxygen vacancy-rich and fluorine-doped carbon-coated Ca2Fe2O5 for improved lithium storage performance

“…24 Besides, the strong absorption peak around 1500 and 580 cm −1 may be due to CO and the M–O bonds, respectively. 25–27 Additionally, the absorption band at wavenumber 3430 cm −1 is also related to the OH stretching vibrations. 25 As shown in Fig.…”

Treatment of Groundwater-Rich Organic Compounds Using Activated Carbon with Additional Germanium Dioxide (GeO2): Kinetics and Adsorption Studies of Methylene Blue and Congo Red

“…The kinetics of the adsorption process can be stated by the Langmuir equation, − with a new transformation which shows a hybrid rate equation − with where q t is the adsorption amount of adsorbent at time t , and q e and q max are the adsorption amounts of adsorbent at equilibrium and maximum capacity, respectively. k a and k d are the adsorption and desorption rate constant, respectively.…”
