Fibrous, ultra-small nanorod-constructed platinum nanocubes directly grown on the ITO substrate and their heterogeneous catalysis application

Abstract

Fibrous, ultra small nanorod-constructed Pt nanocubes (PtNCs) directly grown on the substrate surface show enhanced heterogeneous catalytic reduction of methyl orange with efficiency 10 3 times higher compared to those in homogeneous reaction. The PtNCs may find potential application in organic reactions and photoelectrochemical devices.

Porous (001)-faceted Zn-doped anatase TiO2nanowalls and their heterogeneous photocatalytic characterization

“…10 In addition, these methods realize the formation of (001) faceted anatase TiO 2 in the solution that may limit their usage in particular applications, such as solar cells, optoelectronic devices and heterogeneous catalysis. [20][21][22][23][24][25][26] In this paper, we describe the synthesis of a Zn-doped TiO 2 nanowall (ZnTNW) with a highly porous (001) face directly on the substrate surface via a liquid-phase deposition (LPD) method using a new uoride scavenger, ZnNO 3 , instead of the boric acid, normally used in the LPD process. 11 Although pristine anatase TiO 2 has shown excellent performance in existing applications, metal doping has been discovered to further improve its performance.…”

Porous (001)-faceted anatase TiO2nanorice thin film for efficient dye-sensitized solar cell

“…And in the presence of the surfactant (HMT) here via an effective adhesion of its active amine functional onto the TiO 2 nanocrystallite, presumably on (001) plane, the nanorice of anatase TiO 2 that is bounded by this plane is realized. Such feature has also been found in the one-dimensional crystal growth in the case of ZnO [26,27] and platelet [28,29], brick-shape [30], nanofibrous [31,32] and multipods [33] nanocrystal in the case of Au, Pt and Pd. Therefore, in order to obtain the extent role of HMT in the formation of (001)-faceted TiO 2 nanorice, we examined the nanocrystal growth properties under a different HMT concentration.…”

(001)-Faceted hexagonal ZnO nanoplate thin film synthesis and the heterogeneous catalytic reduction of 4-nitrophenol characterization

“…Nevertheless, although they may effectively grow ZnO nanostructure directly on the substrate surface, the shape-controlled is limitedly achieved. Our group have been focused on the controlled-shape growth of metal and metal oxide on ITO/FTO surface for use in variety of applications [21,22]. Wide range of nanostructure morphologies such as nanotube, nanorod, nanotripod and nanoplates have been obtained so far.…”
