Electronic properties of calcined materials from a scandium-O-phenylene-O-yttrium-O-phenylene hybrid copolymer

Eco-friendly synthesis of core–shell structured (TiO2/Li2CO3) nanomaterials for low cost dye-sensitized solar cells

“…Hence a lot attention has been focused on the development of such type of materials to employ in DSCs. The crucial factor in limiting the efficiency of DSCs is interfacial recombination of the injected electrons from photo excited dye with the dye cations or redox couple (Kontos et al, 2008;Karuppuchamy et al, 2009 layers on the surface of nanoporous films could suppress the recombination in DSCs (Kawahara et al, 2007). The ultimate goal of this overcoat is to increase the physical separation of injected electrons and redox couple/oxidized dye molecules and thus reducing the recombination (Hwang et al, 2010;Bang et al, 2012;Furukawa et al, 2007).…”

Facile synthesis of honeycomb structured SnO/SnO2 nanocomposites by microwave irradiation method

“…In recent years, nanostructured metal oxides have engrossed special attention because of their ideal properties in a broad range of applications [1][2][3][4][5][6][7]. Among the nanostructured metal oxides, SnO 2 and SnO have prolonged prominent interest owing to its potential applications in different fields.…”

Visible light induced electron transfer behavior of a CeO2-loaded HfO2/carbon cluster nanocomposite material

“…Of such materials, carbon cluster-sensitized inorganic semiconductors (composite materials) which are used in photocatalysts are particularly appealing to us and we have a few specific contributions relevant to this field [28][29][30][31][32][33]. In particular, we have reported a novel and relatively simple technique to synthesize a composite material by the calcination of either metal-organic moiety hybrid copolymers or inorganic metal compound/organic polymer complexes [28][29][30][31][32][33]. Indeed, we have observed the electron transfer feature of carbon cluster → HfO 2 in HfO 2 /carbon cluster composite material and CeO 2 → carbon cluster in CeO 2 /carbon cluster composite material.…”
