Decreasing charge recombination by magnetic trap of iron‐carbon (Fe‐AC) composite for enhanced photocatalytic performance

“…The interband transition state in low loss region indicated surface state and the bandgap that are the most important parameter for photocatalytic application can be determined by using reflection electron energy loss (REELS) spectroscopy and the chemical state can be obtained from the core level of Fe 2p, O 1s, and C 1s by using X‐ray photoelectron spectroscopy (XPS). The validity of REELS and XPS spectrum in determining the bandgap and chemical state 24–30 has been reported in various kind of materials including transparent oxide films and composites, 16–18,23 metals and their alloys, 28,29 dielectrics materials, 24,27 and semiconductors 25,26 …”

“…Compound of metal–organic in the form of composite materials is widely used in various fields due to the environmental viability and low density such as dye photo‐degradation, 8,9 catalysts, 8,10 energy storage, 13 electromagnetic wave absorption, 12–15 and drug delivery carrier 13,14 . The stability of bonding between organic carbon atoms and metals atoms in the form of composites has been intensively studied for increasing efficiency in devices' applications 8,13,14,16 …”

“…For photo‐catalytic application, the radiation is used as a source in increasing catalytic activity, some of the oxygen atom at the surface of carbon atom having an energy for breaking the bond. The oxygen loss from the carbon is used for bonding with Fe atoms to form Fe–O 16–19 . Activated carbon (AC) is also having high porous structure due to the high surface area with excellent adsorption capacity.…”

“…The magnetic pore of the composites and the bonding characteristics of oxygen atom at the surface are the basic knowledge for providing connection between the electronic, structural, and magnetic properties to the degradation performance. The chemical modification at the surface as the effect of amount of AC in the composite is important to be analyzed; the electronic, structural, magnetic, absorption, and chemical state properties were influenced to photo‐catalytic materials' performance 14,16,23 . The interband transition state in low loss region indicated surface state and the bandgap that are the most important parameter for photocatalytic application can be determined by using reflection electron energy loss (REELS) spectroscopy and the chemical state can be obtained from the core level of Fe 2p, O 1s, and C 1s by using X‐ray photoelectron spectroscopy (XPS).…”

Study of Crystallinity Extract Cellulose from Corn Stalk Fiber

“…Spectra of XRD Cellulose from corn stalk fiber Miller indices (hkl) show peaks 110, 110, 102, 200, 400 with angles theta (θ) 12.16 o , 14.75 o ,18.36 o , 21.96 o , 33.95 o infigure 3. The small diffraction peaks indicate areas of high crystallinity[17].…”
