Oxygen-vacancy abundant alpha bismuth oxide with enhanced cycle stability for high-energy hybrid supercapacitor electrodes

Tailoring the Perovskite Structure to Acquire an Inorganic La2NiCrO6 Double Perovskite as an Efficient Energy Storage Application by Varying Molar Concentrations of Citric Acid

“…A decrease in the loading mass of active material during the initial cycles causes a rapid decline in capacitance up to 2000 cycles. 46 After that, there is no material detachment from the electrode surface; hence, after 2000 cycles, the specific capacity remains the same up to 10,000 cycles, showing the better cycle stability of the LNC3 material. Further, the electrical properties of the synthesized material were characterized by studying the diffusion of ions in the electrode materials.…”

Controllable vacancy strategy mediated by organic ligands of nickel fluoride alkoxides for high-performance aqueous energy storage

“…50 The Warburg impedance ( Z w ) due to ion diffusion is characterized by a linear curve in the low-frequency region. 51 It can be seen that the R ct values of candidate samples increased significantly with the length of the carbon chain of solvents used for synthesis, which can be attributed to the reduction in the relative number of hydrogen bonds formed with F − leading to reduced vacancies. For a more accurate comparison between all candidate electrodes, the Nyquist plots were fitted with the equivalent circuit as shown in Fig.…”

A novel bismuth hydroxide (Bi(OH)3) semiconductor with highly-efficient photocatalytic activity

“…3b further verified the presence of adsorbed hydroxide species (Bi–OH) from the O–H bond at 532.02 eV 13 and lattice oxygen of the Bi–O bond at 529.41 eV in the Bi(OH) 3 sample, and the peak located at 530.5 eV was the signal of oxygen atoms in the vicinity of an OV. 18,19 Under irradiation, Bi(OH) 3 inevitably dehydrated to some extent to form Bi 2 O 3 as a hydroxide, which can also be seen in the XRD pattern after illumination with the appearance of Bi 2 O 3 characteristic peaks (Fig. S2b, ESI†).…”
