Enhanced electrochemical performance by nickel-iron layered double hydroxides (LDH) coated on Fe3O4 as a cathode catalyst for single-chamber microbial fuel cells

Ultrasound-excited hydrogen radical from NiFe layered double hydroxide for preparation of ultrafine supported Ru nanocatalysts in hydrogen storage of N-ethylcarbazole

“…6 (a) and (b), compared with NiFe-LDH support, the peaks of 5Ru/NiFe-LDH-A catalyst had no obvious changes. For NiFe-LDH, the peak at 3442 cm −1 was ascribed to the stretching vibration peak of the hydroxyl groups on the layer and interlayer water molecules [47] . However, the hydroxyls peak position of 5Ru/NiFe-LDH-300–60 obtained by ultrasound-assisted reduction moved to the lower wavenumber.…”

Magnetic Fe3O4@CoFe-LDH nanocomposite heterogeneously activated peroxymonosulfate for degradation of azo-dye AO7

“…These results suggested that the hybrids were successfully synthesized and consisted of Fe 3 O 4 and LDH. 30 The FT-IR spectra of Fe 3 O 4 , CoFe-LDH11 and Fe 3 O 4 @CoFe-LDH11 are shown in Fig. 2b .…”

“…Besides, the magnetic Fe 3 O 4 @CoFe-LDH11 showed a sharp band at 627 cm −1 , indicating the formation of Fe–O–Fe between Fe 3 O 4 and LDH. 30 …”

Enhancing the anode performance of microbial fuel cells in the treatment of oil-based drill sludge by adjusting the stirring rate and supplementing oil-based drill cuttings

“…5 (c), where the correlation coe cient of the former (R 2 =0.92) was less than that of the latter (R 2 =0.98), which indicated that diffusion control was the dominant position and adsorption control was the non-dominant position. The value of the diffusion control constant (k) re ected the substantial catalytic oxidation-reduction reaction (ORR) and electrochemical performance of the electrode compared with a previous study (Jiang et al 2020). This improvement was attributed to the formation of stable bio lms on the electrode surface at the end of operation.…”
