Platinum, from a solution of chloroplatinic acid hexaidrated in isopropanol, was photochemically reduced at the beginning of the photocatalytic process, by its addition in a mixture containing 600 mL of Milli-Q water and 150 mL of methanol, used as sacrificial reagent (20% v/v).
One of the reasons for the selection of chloroplatinic acid for dispersion is that the ionic structure between N atoms in the PANI chains and chloroplatinic acid can improve both electrical conductivity and thermal stability of PANI.
The platinum catalyst, obtained from a 40 mM chloroplatinic acid solution (Sigma-Aldrich) in 2-propanol (Sigma-Aldrich), was deposited on the transparent conductor to obtain the Sn[O.sub.2]:F/Pt junction, which was heated at 130[degrees]C in air for 3 min to evaporate the solvent.
2.5 [micro]L chloroplatinic acid solution (10 mg/L), as the assistant catalyst, was added into the solution.
The catalysts were prepared by impregnating the aqueous solution of chloroplatinic acid ([H.sub.2]Pt[Cl.sub.6]) as a precursor using the incipient impregnation wetness method.
Patch clamp glass (OD/ID: 1.65/1.1 mm) (World Precision Instruments, USA), silver paste (Sigma-Aldrich, USA), chloroplatinic acid--[H.sub.2]PtC[l.sub.6] (Sigma-Aldrich, USA), hydrogen peroxide solution, 30 % (w/w) in [H.sub.2]O (Sigma-Aldrich, USA), phosphate buffered saline (PBS) (Sigma-Aldrich, USA), hydrogen chloride (HCl) (Sigma-Aldrich, USA), ferrocenemethanol (FMA) 97% (Sigma-Aldrich, USA).
The ethanol solution of chloroplatinic acid hexahydrate was used to prepare the counter electrodes.
The catalyst paste contains vinyl-terminated poly (dimethylsiloxane) and a catalyst such as chloroplatinic acid.8,10-12 The fillers, such as amorphous silica or fluorocarbons, are added to both the pastes to improve mechanical properties.7,10 The VPS impression materials are presented in different viscosities; extra light-bodied, light-bodied, medium-bodied, heavy-bodied and putty.8,10,13 When the two pastes are mixed, an addition polymerisation reaction occurs forming a cross-linked molecules in the set state.7,12,14,15
Platinum-based homogeneous strong acids like chloroplatinic acid (Karstedt acid) are typically used here and the cures can either be at ambient or higher temperatures.
These oligomers are double-bond-functional silicones which become polymerized by free radicals from chloroplatinic acid.
Pt particles were deposited on the working electrode under galvanostatic condition using +2.5mA/[cm.sup.2] current for 30 minutes from chloroplatinic acid solution.
