Characterisation of well-adhered ZrO2 layers produced on structured reactors using the sonochemical sol–gel method

Preparation of the Nanodiamond@SiO2 Abrasive and its Effect on the Polishing Performance of Zirconia Ceramics

“…The binding energy of 182.45 eV and 184.14 eV correspond to Zr 3d in the ZrO 2 state, respectively. 34 And the binding energy of 181.81 eV and 184.83 eV accordingly correspond to Zr 3d in the ZrSiO 4 state. 35 Based on the above XPS analysis of Si, O and Zr elements, the main chemical formulas of the reaction can be deduced as Eqs.…”

Enhanced acetic acid sensing of MOF-derived α-Fe2O3/ZrO2 arising from phase junction and defects

“…1(c). The peaks in the spectra of Fe/Zr-0 at 140, 260, 412 and 620 cm À1 pertain to the typical Raman features of t-ZrO 2 , 41 and the peak of 204 cm À1 belongs to Fe-O; the 558 cm À1 (m-ZrO 2 ) and 290 cm À1 (t-ZrO 2 ) peaks are indexed to the Zr-O vibration, which simultaneously appear in Fe/Zr-x (x = 1, 2 and 4), 42,43 in accordance with the XRD and FT-IR analysis. Relative to Fe/Zr-0, the Fe-O peak in other a-Fe 2 O 3 /ZrO 2 significantly shifts to 227 cm À1 and emerges broadened, possibly caused by the high concentration of defects.…”

Sonochemical catalysis as a unique strategy for the fabrication of nano-/micro-structured inorganics

“…The final ZnO nanorods had a width of about 30 nm and lengths of 50-70 nm. To obtain thin ZrO 2 layers on structured reactors, Jodłowski developed an efficient ultrasound-assisted sol-gel method through the synergistic combination of three processes: [123] Sonochemical synthesis of Zr sol-gel from a Zr(IV) precursor solution, addition of ethylene glycol and glycero as stabilizing agents, and deposition of ZrO 2 on the FeCr Alloy supports. The resultant ZrO 2 films on the metallic structure were dense and uniform without any impurities.…”
