Fe3O4 nanoparticles was in cubic spinel crystal structure with average crystalline size of (62.1 ± 5.7) nm. The photocatalyst loading (0.5 — 3.5wt%), initial dye concentration (MB: 2-12 ppm, PR: 8 — 48 ppm, MO: 12 — 32 ppm) and irradiation duration on the decolourisation of ...
A coating resistant to FeCl3 (e.g. Fe3O4 or iron phosphate) is then applied to the electrode except in the holes. The mask so obtd. is used to expose a light-sensitive layer on a glass plate so that a luminescent screen is produced, after which the electrode is etched a second ...
Raman spectroscopy reveals the presence of ZnO, 尾-FeOOH, white rust, green rust, FeCl2, Fe3O4, FeOH, Fe2O3 and 未-FeOH for salt spray tested samples, but for 100% humidity test, only ZnO is revealed.YADAV, M.SAHA, J. K.
