“…The absorption internal Si-O-Al bonds appeared at 427 and 449 cm -1 for NiA and NiX zeolites, respectively [70]. Two absorption bands of NiX zeolite at 914 and 748 cm -1 could be associated with the stretching of Al-O bonds [54]. In addition, two bands were detected in the absorption region from 700 to 500 cm -1 in spectrum of NiX zeolite, first band at 682 cm -1 attributed to the double rings stretching and second, main structural sensitive band in the spectrum of faujasite, at 559 cm -1 which corresponds to the double six-membered rings vibration stretching.…”

“…An increase in the number of metal ions in the zeolite would favour this reaction by the production of more protons. In the NiX spectrum, a shoulder was noticed at 1072 cm -1 which could correspond to Si-O-Si vibrations [54,69,70]. The absorption internal Si-O-Al bonds appeared at 427 and 449 cm -1 for NiA and NiX zeolites, respectively [70].…”

“…Namely, it has been observed that, during OER on Ni surface, NiO is firstly formed and then it is electrochemically oxidized to Ni 2 O 3 [41]. Zeolites are recently finding application in electrochemistry area, in electroanalysis [53,54], as well as in electrochemical energy conversion and storage [55][56][57][58][59]. Thus, Pt-, Pd-and Niion exchanged zeolites were tested as anode electrocatalysts in fuel cells for oxidation of fuels such as alcohols and borohydride [57,[59][60][61][62][63].…”

NiA and NiX zeolites were prepared and characterised using XRD, FTIR and SEM, and subsequently tested as electrodes for hydrogen (HER) and oxygen (OER) evolution reactions in alkaline media. Linear sweep voltammetry and chronoamperometry techniques showed that NiA has higher catalytic activity for these two reactions, as evidenced by higher current densities, which can be correlated with a higher weight fraction of Ni in this electrocatalyst than in the NiX and with its higher conductivity. HER and OER kinetic parameters, including Tafel slope, exchange current density and apparent activation energy were evaluated. Electrochemical impedance spectroscopy analysis yielded values of the resistance of the solution, charge transfer and mass transfer, as well as double layer capacitance and pseudo-capacitance of the working electrode, at different potentials and temperatures. Unlike the HER, during which the mass transfer resistance of the adsorbed intermediate is dominant in the case of NiA, the OER impedance response is controlled by the charge transfer process itself at the potentials of interest for these process. The overall resistance related to the HER is lower for NiA than for NiX.

“…With the aid of the electro-Fenton process, some scholars successfully degraded p-nitrophenol in water with CNTmodified nickel foam electrode, and concluded that the porosity of the CNT enhanced the electro-Fenton effect, making the electrode highly reusable [10][11][12][13][14]. Through structural and morphology analysis, related researches compared the nickel foam system and cooper foam system in p-nitrophenol degradation, and confirmed that the latter has the better degradation effect but the former has the better stability [15][16][17][18][19][20][21].…”

This paper mainly compares the electroreduction of p-nitrophenol by different surfactantmodified chemical electrodes. Four surfactants were prepared to modify the glassy carbon electrode, including a cationic surfactant (CTAB), an anionic surfactant (SDBS) and two nonionic surfactants (Tween 80, OP-10). Each modified electrode was applied to detect the p-nitrophenol in sodium acetate buffer solution, and the reduction peak current and reduction peak potential of p-nitrophenol were measured by linear sweep voltammetry under different concentrations of each surfactant. The results show that the cationic surfactant reduced the peak current, reaching the optimal effect at the concentration of 2.95×10-4 mol/L; the anionic surfactant and nonionic surfactants reduced the peak current, and the reduction effect depends on the micelle effect of the surfactants and other factors; the cationic surfactant suppressed the reduction peak potential at concentrations of 0 ~ 2×10-4 mol/L, while the other three surfactants cannot reduce the reduction peak potential; the CTAB was proved as the most sensitive material for detecting p-nitrophenol on electrode surface. This research provides a valuable reference for the design of p-nitrophenol sensors.
