Transition Metal Oxides

Grain boundaries in nanocrystalline catalytic materials as a source of surface chemical functionality

“…Templating (especially hard-templating) assumes growth of nanoparticles of catalytic materials inside the channels of a hard scaffold, i.e., in anodized alumina membranes, mesostructured silicas of MCM-41, SBA-15, KIT-6 or SBA-16 types, affecting the assembles geometry by restricted growth in some directions (Landau 2002, Landau and Vradman 2009, Gu and Schueth 2014. Electro-deposition of Pt or Pt-Ru in the channels of anodized alumina membrane filled them with nanowires of 50-60 nm in diameter whose length increased with the metals loading (Napolskii et al 2007).…”

An oxide chain constructed from octamolybdate, a Keggin anion and a copper (II) – Tetrapyridylpyrazine binuclear unit

“…The Cu(II) sites are inequivalent with one copper bonding to two pyridyl donors and a pyrazine nitrogen of one terminus of the tpyprz ligand, two aqua ligands and an oxo-group of the b À Mo 8 Solid state oxides exist for a majority of the elements and are thus ubiquitous in the geosphere, biosphere and noosphere [1][2][3][4]. Inorganic oxides offer a vast compositional range and unusual structural diversity, giving rise to a multitude of physical properties and applications ranging from heavy construction to molecular electronics [5][6][7][8][9][10][11][12]. The fundamental and practical significance of these materials has led to considerable interest in the development of synthetic approaches to novel oxide materials.…”

Solid state coordination chemistry of polyoxomolybdate clusters: Hydrothermal synthesis and structures of and (Hpt=5(4′-pyridyl)tetrazole)

“…The significant contemporary interest in inorganic oxides reflects their vast compositional range and considerable structural diversity, characteristics related to a range of useful physical properties and applications [1][2][3][4][5][6][7][8][9][10][11]. The rational design of new oxide phases drives the development of synthetic strategies.…”
