Tin oxide, antimony-doped

The surface of ATO was modified by the grafting-from method the specific steps were as follows The ATO nanoparticles with 5 mol% of doped antimony were first activated by KH550. Then, PMMA was grafted onto the ATO nanoparticles via radical polymerization. The obtained modified nanoparticles were characterized by FTIR, TG, sedimentation test, SEM, and XRD. AU results showed that the PMMA had been grafted onto the surface of ATO. 

The ATO powder was added into the PMMA matrix by solution blending. The PMMA-modified ATO nanoparticles were added into a tetrahydrofuran solution of PMMA to prepare ATO/PMMA nanocomposites. The composites showed high conductivity and good transparency.

The electrocatalytic materials were deposited onto ceramic sheets in the form of nanosized parricle-containing inks. The electrocatalytic ink was prepared from carbon black-supported antimony-doped tin oxide. Comparisons were made between the commercially available Sb-doped SnOa as well as the Sb-doped Sn02 prepared by a solgel method. 

Vilker et al. were able to transfer the reducing equivalents to purified cytochrome CYPIOI through its natural redox partner putidaredoxin using an antimony-doped tin oxide working electrode, thus avoiding the reductase and NADH. The required oxygen was supplied at a platinum counter electrode by water electrolysis as shown in Fig. 31. A continuous catalytic cycle was sustained for more than 5h, and 2600 enzyme turnovers were obtained at a maximum production rate of 36 nmol S-C-vo-hydroxycamphor/nmol CYPlOl/min [151],... 

As a reference system, antimony doped tin oxide nanoparticles were added to the sol at the same weight percent as was nsed for the dye. In this case, the resrrlting composite was foimd to be of significantly rednced porosity, supporting the snpposition that the hydrophobic interactions between the dye and the Plmonic P123 drive the formation of the rod-shape mesostractures. The porosity difference between the dye and nanoparticle containing composites can is shown in Fig. 3.

There are several different metal oxides with optical band gaps of 2.5 to 4 eV, which are useful for transparent conducting oxide (TCO) coatings. The most common of these are tin-doped indium oxide (ITO), fluorine or antimony-doped tin oxide and doped zinc oxides. The preparation and physical properties of these materials prepared by CVD will be discussed.

The ORDE consists of a quartz rod, polished at both ends, one of which is coated with a quasi-metallic antimony-doped tin oxide film to form a (semi-) transparent disc electrode. Light is shone down the rod and through the disc electrode as it is rotated in solution. The rotation of the ORDE imposes RDE hydrodynamics at the transparent... 

The most commonly encountered TCO electrodes, typically studied as thin films, are antimony-doped tin oxide (ATO) or fluorine-doped tin oxide (FTO), ITO, titanium oxide (anatase or rutile, Ti02), and zinc oxide (ZnO) [19], There are also some recently reported trinary and ternary oxides based on modifications of ITO, zinc-indium tin oxide, ZITO or IZTO, for example, which may become more popular with time as electrodes for solution-based redox chemistry and as anodes in devices such as OLEDs and OPVs [7], These new tailored composition oxides may exhibit higher stability, higher work functions, and/or a greater variety of surface sites with more possibilities for chemical modification.
