Study of Nanocomposites of Silicon Structures for use in Mechatronics

Abstract

of Pt to the formation of a Schottky barrier at the metal- TiO 2 -terface. This happens because the work function of Pt 5,36-5,63 eV) is greater than that of TiO 2 (~ 4,6-4,7 eV), so that electrons are transferred at Pt and holes Localized in TiO 2 media to improve photocatalytic efficiency. In order to improve the Pt/TiO 2 composites, steps have been taken to optimize the interaction between Pt and TiO 2 from Kandiel, effectively effecting the surface area and crystal structure of TiO 2 in the resulting Pt/TiO 2 composite and demon strating that although the large Area is useful, increasing crystallinity is preferential. Increasing photocatalytic activity is due to the reduction of site defects that act as charge recombination centers when crystallinity increases. Abstract This article analyzes the developments on the subject and draws conclusions for the study 1722/М - 2017 at the UZNIT of TU - Gabrovo BG. Most metals are highly chemically reactive, especially at nanoscale, without having properties that can be easily used with TiO2 composites. As such, most of the metals below will be considered metal oxides of precious metals. In addition, the most common oxide TiO2 will be discussed, as other oxides are probably unstable and thus do not form stable composites.
