Embodiment 1

[0016] Example 1: (EuBW / RuBPBH) n Film preparation

[0017] Cleaning of the substrate: 30% H 2 o 2 with 98% H 2 SO 4 After mixing in a ratio of 3:7 by volume, put the quartz substrate in it and soak for 2 hours, take it out, wash it fully with distilled water, and dry it; the ITO conductive glass substrate can be cleaned with detergent, and then washed with distilled water. blow dry.

[0018] Hydroxylation of the substrate: the concentrated NH 3 ·H 2 O, 30%H 2 o 2 ) and H 2 O was mixed evenly at a volume ratio of 1:1:5, heated to 70°C, immersed in the clean substrate for 20 minutes, fully washed with distilled water after taking it out, and air-dried.

[0019]Silanization of the substrate: Prepare an ethanol solution of 3-aminopropyl-triethoxysilane with a volume ratio of 5%, immerse the hydroxylated substrate in it for 8 hours, take it out, wash it with absolute ethanol, and air blow dry.

[0020] Protonation of the substrate: immerse the silanized substrate in a ...

Embodiment 2

[0023] Embodiment 2: the electrochemical test of film

[0024] The electrochemical test of the thin film is carried out on a CHI601 electrochemical analyzer of Shanghai Chenhua Instrument Co., Ltd. using a three-electrode system. The specific test process is: (EuBW / RuBPBH) deposited on the ITO substrate n Thin film as working electrode, platinum wire as counter electrode, saturated calomel electrode as reference electrode, 0.2mol L -1 Na 2 SO 4 The aqueous solution is used as the electrolyte solution, and the cyclic voltammetry test is carried out at room temperature; in the electrocatalysis experiment, the electrode system remains unchanged, and the electrode system is increased to 0.2mol L -1 Na 2 SO 4 Different concentrations of sodium nitrite were added to the electrolyte, and the cyclic voltammetry test was carried out at room temperature.

Abstract

The invention provides a self-assembly hybrid film with oxidation-reduction activity of rare earth heteropolymetalate and binuclear ruthenium (II) complex, and relates to a preparation method for the self-assembly film of the rare earth heteropolymetalate and the binuclear ruthenium (II) complex as well as evaluation of the electrocatalytic oxidation activity to nitrite. The film is prepared from the rare earth heteropolymetalate K15[Eu(BW11O39)2] and the binuclear ruthenium (II) complex [RuBPBH](ClO4)4 through an electrostatic layer-by-layer self-assembly method. Three-layer (EuBW / RuBPBH)3 film modified electrodes have remarkable electrocatalytic oxidation effect on the nitrite, catalytic peak current and the concentration of sodium nitrite are in a linear relationship within certain concentration range, and the self-assembly hybrid film has potential application prospects in 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 from a binuclear ruthenium complex and a rare earth heteropoly complex. Background technique [0002] In recent years, because hybrid materials can achieve molecular-level recombination between materials with different properties, so that the properties of their components can be complemented and optimized, they have attracted widespread attention. [0003] Heteropoly complexes are a kind of metal-oxygen clusters with a polyhedral structure formed by the polymerization of MOx polyhedra through sharing edges, sharing corners, and sharing vertices. They have special acidity and oxidation properties, combined with structural and electronic diversity. It has important theoretical research value and broad application prospects in the fields of catalysis, biology, medicine and materials, and its properties can be adjusted by adjusting the compo...
