Sol–gel La 2 O 3 –ZrO 2 mixed oxide catalysts for biodiesel production

“…This behavior indicates that up to 3% La 2 O 3 , single-layer La 2 O 3 covers 64% of ZrO 2 and that for a larger content (5% La 2 O 3 ), multilayer La 2 O 3 forms on ZrO 2 . 2-→ Zr 4 + charge transfer transition with Zr in low coordination states [54] associated with the excitation electron from valence band to conduction band [55] . Table 1 shows the band gap energies, E g , for the prepared pure ZrO 2 (0% La 2 O 3 ) and La 2 O 3 -ZrO 2 mixed oxides.…”

A Comparable Study of Structural, Dielectric and Humidity Sensing Properties of Solution Combustion Synthesized ZrO2 and ZrTiO4 Nano Powders

“…To synthesize ZrO2 we followed the same procedure as we did earlier [8]. To synthesize ZrTiO4 nano powder Titanium nitrate [TiO(NO3)2] and Zirconyl nitrate [ZrO (NO3)2.XH2O] (Central Drug House (P) Ltd.) were used as oxidizers.…”

“…Consentino et al [7] prepared ceramic powders from the mixture of zirconium oxychloride and titanium chloride in stoichiometric quantities in the presence of citric acid. At the present work we prepare ZrTiO4 nano crystals with multi phases by solution combustion method by using Glycine as a fuel and we are comparing the results with ZrO2 prepared by solution combustion method as prepared earlier by few workers [8]. The obtained samples are analyzed by XRD, SEM, AC conductivity and humidity sensing properties.…”

Humidity Sensors Based on High Performance Graphene/Zirconium Dioxide Nanocomposite Material

“…Below 1150 ℃, this ceramic material has a monoclinic structure with high degree of thermal and chemical stability and excellent toughness. (15) This has led numerous researchers to investigate the application of ZrO 2 materials in humidity sensors. (7,(16)(17)(18) Unfortunately, the sensing performance of ZrO 2 is inhibited by pronounced hysteresis.…”
