Synthesis of a magnetically separable LDH-based S-scheme nano-heterojunction for the activation of peroxymonosulfate towards the efficient visible-light photodegradation of diethyl phthalate

“…On the other hand, the attendance of Cr 3+ was studied through the ascribed fine spectra Cr 2p. The peaks settled at 577.38 affirmed Cr 2P 3/2 state; whereas, the Cr 2p 1/2 state was confirmed with the appeared peak at 587.1 eV [36,37]. Lastly, the recorded high-resolution Fe 2p spectrum implied the presence of Fe 2+ and Fe 3+ on the surface of the sample by observing two main peaks with their 15 satellite peaks located at the binding energy of 705-735 [38].…”

“…Given that, Cu 2+ was recognized by the emergence of the distinct peaks at the binding energies of 960.59, 951.9, 941.36, and 933 eV. In this context, the peaks at 951.9 eV and 933 eV verify the Cu 2p 1/2 and Cu 2p 3/2 signals, respectively [34][35][36]. On the other hand, the attendance of Cr 3+ was studied through the ascribed fine spectra Cr 2p.…”

Au-Mediated Charge Transfer Process of Ternary Cu2O/Au/TiO2-NAs Nanoheterostructures for Improved Photoelectrochemical Performance

“…The Nyquist plots are generated between the imaginary component of the impedance ( Z ″) and the real component ( Z ′). In the equivalent circuit, R s , R ct , W s , and CPE represented the solution resistance, CT resistance, Warburg impedance, and constant phase element of the non-ideal frequency-dependent capacitance, respectively . All curves exhibited the characteristic arc spectra, in which the smaller arc represents the lower CT resistance at the interface between the electrode and electrolyte.…”

“…In the equivalent circuit, R s , R ct , W s , and CPE represented the solution resistance, CT resistance, Warburg impedance, and constant phase element of the non-ideal frequencydependent capacitance, respectively. 43 All curves exhibited the characteristic arc spectra, in which the smaller arc represents the lower CT resistance at the interface between the electrode and electrolyte. It has been found that the arc radius on the plot of the Cu In order to further clarify the separation efficiency of photogenerated charge carriers of as-prepared specimens, amperometric I−t curves were recorded and are exhibited in Figure S6 (Supporting Information).…”

Recent Advancements on Biopolymer‐ Based Flexible Electrolytes for Next‐Gen Supercaps and Batteries: A Brief Sketch

“…Environmental friendliness and outstanding safety are the primary features of energy storage devices (ESD) that researchers look out for while engaged on work related to alternative sources of energy [1–3] . The challenging area with regard to the energy sector revolves around the advancements in developing flexible and self‐healing ESD that play an inevitable part in making a headway in wearable electronics [4] .…”
