Embodiment 1

[0015] Example 1: {BW 11 Zn / Ru(IPTP) 2} n Film preparation

[0016] Cleaning of the substrate: place the quartz substrate in newly prepared 30% H 2 o2 with 98% H 2 SO 4 Soak in (3:7v / v) mixture for 2h, take it out and wash it with distilled water; then immerse in NH 3 ·H 2 O(25%):H 2 o 2 (30%): H 2 O=1:1:5 (V / V / V) in a 70°C mixture for 20 minutes, take it out, wash it with distilled water, and dry it with air. For the ITO conductive glass substrate, wash it with detergent first, take it out, wash it with distilled water, and then immerse it in NH 3 ·H 2 O(25%):H 2 o 2 (30%): H 2 O=1:1:5 (V / V / V) in a 70°C mixture for 20 minutes, take it out, wash it with distilled water, and dry it with air.

[0017] Silanization and protonation of the substrate: immerse the cleaned substrate in a 5% (v / v) ethanol solution of 3-aminopropyl-triethoxysilane for 8 hours, take it out, wash it with ethanol, and air blow dry. Then immerse the silanized substrate in the hydrochloric a...

Abstract

The invention provides a heteropoly compound and ruthenium (II) compound self-assembled hybrid film with dual-functional electro-catalytic activity, and relates to a method for preparing a heteropoly compound and ruthenium (II) compound self-assembled film and evaluation on activity of electro-catalytic reduction and electro-catalytic oxidation. The film is prepared from K7 [BW11O39Zn(H2O)] and a ruthenium (II) compound [Ru(IPTP)2](ClO4)2 by an electrostatic layer-by-layer self-assembly method. When outer layer ingredients of the film are different, the film has a dual functional catalytic effect of electro-catalytic reduction and electro-catalytic oxidation, so that the film has potential application prospect in the field of chemical sensors.

Description

technical field [0001] The invention relates to a hybrid thin film formed by two components, in particular to a hybrid thin film assembled by a heteropoly complex and a ruthenium (II) complex. Background technique [0002] As a class of metal oxygen cluster compounds, heteropoly complexes have unique structures and excellent physical and chemical properties, which make them have important theoretical research value and broad application prospects in the fields of catalysis, medicine and material chemistry. Its properties can be adjusted by adjusting the structure and elemental composition of heteropoly complexes. At present, there are a large number of research work reports on the electrocatalytic performance of heteropoly complex modified electrodes in the literature, such as Keggin structure heteropoly acid SiMo 11 VO 40 5- A multilayer film modified electrode formed with poly(diallyldimethylammonium chloride) paired with HNO 2 The reduction reaction has good electroca...
