“…Additionally, the Mo 3d spectrum shows two peaks due to the spin-orbit split effect at 232.3 eV (3d 5/2 ) and 235.5 eV (3d 3/2 ) that are assigned to the Mo 6+ state. 18,28 It is possible that the compensation produced by the Ce 3+ doping at the Bi 3+ sites was achieved by the formation of the solid solution.…”

This research work focuses on developing a robust polymer electrolyte membrane (PEM) with high proton efficiency toward proton exchange membrane fuel cells (PEMFCs). In this study, poly ether sulfone (PES) was sulfonated by chlorosulfonic acid to yield sulfonated poly ether sulfone (SPES) followed by incorporation with bismuth-based additives such as bismuth trimesic acid (BiTMA) and bismuth molybdenum oxide (Bi 2 MoO 6 ). The composite membrane was thoroughly investigated for its structural and physicochemical properties such as FT-IR, SEM, TGA, contact angle, water uptake, oxidative stability, ion-exchange capacity, and swelling ratio. Incorporation of additives into the polymer was confirmed by XPS and XRD analysis. The proton conductance of the pristine SPES is 4.19 × 10 −3 S cm −1 , whereas that of the composite membrane SPES/BiTMA-10 is 10 × 10 −3 S cm −1 and that of SPES/Bi 2 MoO 6 -15 is 7.314 × 10 −3 S cm −1 ; both the composite membranes exhibit higher proton conductivity than the pristine SPES membrane. The physicochemical characteristics and impedance measurements of the electrolyte reported can be viable to the PEM membrane.

Polyethylene glycol (PEG) modified Na2Ti6O13(m = gram of PEG in the precursor) samples are synthesized via a sol–gel method to determine the effects of PEG on the porosity and activity of Na2Ti6O13. PEG prohibited the growth of Na2Ti6O13 crystals in a rhombic system. The Na2Ti6O13(m) samples prepared using PEG are quite porous without large and dense particles. PEG obviously increased the porosity in Na2Ti6O13(m), while the specific surface area increased from 4.3 m2 g−1 (Na2Ti6O13) to 15.7 m2 g−1 (Na2Ti6O13(1.5)), and the pore volume increased from 0.0072 to 0.0265 cm3 g−1 at the same time. The bandgap energies of Na2Ti6O13, Na2Ti6O13(0.5), Na2Ti6O13(1.5) and Na2Ti6O13(2.5) are 3.15, 3.31, 3.53, and 3.58 eV, respectively. The photoluminescence intensities of the Na2Ti6O13(m) samples are in the reducing sequence: Na2Ti6O13, Na2Ti6O13(2.5), Na2Ti6O13(0.5) and Na2Ti6O13(1.5). The initial ofloxacin molecules in the solution are almost fully degraded after 70 min of irradiation using Na2Ti6O13(1.5), while the degradation efficiency of Na2Ti6O13 is only 61.0% at the same time.
