“…227 Besides, decomposition of NO has been suggested to occur in Lewis acid sites of zirconia nanoparticles, 228 synthesis of aromatic aldehydes by the hydrogenation of carboxylic acids with a ZrO 2 catalyst has been already established 229 and various authors have reported on the catalytic activity of zirconia for the selective dehydration of secondary alcohols to terminal alkenes as well as for the hydrogenation of CO to isobutene. [230][231][232] The strength of Zr IV -O bonds has been exploited to develop highly stable metal-organic frameworks (MOFs) that are tolerant to extreme conditions, including chemical functionalization and catalytic reactions and they possess high mechanical strength and high thermal and chemical stability (up to B500 1C, pH 1-10). 233 UiO-66 is composed of [Zr 6 (m 3 -O) 4 (m 3 -OH) 4 ] 12+ nodes, each linked to 12 carboxylates of terephthalate ligands to form tetrahedral and octahedral cages; however, there are many defects from missing linkers in this MOF, with the resulting otherwise open metal sites occupied by hydroxo ligands.…”

“…In case of catalysts 5Ru/TiO 2 -ZrO 2 and 6Ru/TiO 2 -ZrO 2 , moderate and strong acid sites are found to increase with the increase of ruthenium loading. It is interesting to note that the acidity values of 3Ru/TiO 2 -ZrO 2 -6Ru/TiO 2 -ZrO 2 are decreasing due to increase in Ru-metal percentage on acidic titania-zirconia support [18][19][20][21][22][23][24].…”

Vapor phase hydrogenolysis of glycerol was studied over Ru catalysts supported on TiO 2 -ZrO 2 binary oxide. Ru catalysts with various ruthenium loadings from 1.0 to 6.0 wt% were prepared by deposition-precipitation method on the TiO 2 -ZrO 2 mixed oxide support. These catalysts were characterized by X-ray diffraction, H 2 temperature-programmed reduction, NH 3 temperatureprogrammed desorption, transmission electron microscopy, BET surface area, XPS and CO chemisorption measurements. The catalysts exhibited superior performance for the vapor phase hydrogenolysis of glycerol at moderate temperature and atmospheric pressure. The mixed oxide support plays a significant role in improving the catalytic activity for the production of propanediols. The glycerol conversion and the selectivity of various products depend on the catalyst preparation method and also on the Ru content. The influence of acidity of the catalyst and its correlation to the catalytic performance (selectivity and conversion) has been studied. The weak and strong acidic sites of the catalysts measured by NH 3 -TPD play a key role in selective formation of 1,2-propanediol and 1,3-propanediol. XRD, TEM, XPS and CO chemisorption studies revealed that ruthenium was well dispersed on TiO 2 -ZrO 2 which further contributed to the superior catalytic activity for glycerol hydrogenolysis.

“…Zirconia (or doped zirconia) dispersed in ceramics has long been applied to increase the fracture toughness, strength, and hardness [1 3]. A widely used catalyst and catalyst support, zirconia catalyzes alcohol dehydration [4,5], CO/CO 2 hydrogenation [6], alkane isomerization [7], selective oxidation of alcohols and alkanes [8,9], hydrogenation of olefins [10], and isomerization of olefi ns and epoxides [11,12]. Different zirconia phases (monoclinic and tetragonal) exhibit different catalyst selectivities, such as in the selective hydrogenation of CO and alkane isomerization reactions [13 15].…”

Monodisperse and pure phase zirconia (tetragonal: T-ZrO 2 ; monoclinic: M-ZrO 2 ) nanocrystals with fi nely tuned sizes as well as ultrathin T-ZrO 2 nanowires have been selectively synthesized by a facile solvothermal method. For the fi rst time, a diagram of the size to effective strain was mapped for both T-ZrO 2 and M-ZrO 2 , which gives a good explanation for the size-and cation doping-dependent stability of the two phases on the sub-10 nm scale. This work may expand our understanding of the phase properties of not only zirconia, but also various other polymorphic nanocrystals.
