Abstract

The invention relates to a preparation method of a nano TiO2 film electrode. The method comprises the following steps: dissolving 10mL of tetrabutyl titanate in 20mL of anhydrous ethanol, adding 3mL of triethanolamine, sufficiently stirring for 1 hour, adding 2.4mL of polyethyleneglycol (PEG) 8000, continuing stirring for 2 hours to obtain a uniform transparent sol, coating a film on the surface of indium tin oxide (ITO) conducting glass, drying the wet film at 100 DEG C for 5 minutes, coating another film, and drying; and carrying out programmed heating to 700 DEG C at the heating rate of 5 DEG C/minute, calcining at 700 DEG C for 2 hours, and naturally cooling to room temperature, thereby obtaining the nano TiO2 film electrode. The method has the advantages of simple synthesis technique, mild reaction conditions, lower production cost and favorable repeatability.

Description

A kind of preparation method of nanometer titania thin films electrode
Technical field
The present invention relates to material synthesis method, particularly a kind of nano-TiO2The preparation method of membrane electrode.
Background technology
TiO2Photocatalyst has photocatalytic activity height, stable chemical nature, degradation of organic substances and thoroughly and not causes secondary The advantages such as pollution, thus obtained studying widely at sewage treatment area.But due to nano-TiO2Quantum yield is low, and light rings Narrow range is answered to limit its practical ranges.Many studies have shown that, the photo-electrocatalytic technology grown up based on photocatalysis Nano-TiO can be improved2In electronics efficiency of transmission from valence band to conduction band, thus realize with hole (carrier) effectively point From, make photocatalysis efficiency be greatly improved.The another one advantage of photo-electrocatalytic technology is, available electrochemical test system is real-time Photocatalysis electric current under monitoring transient state or stable state and device electricity, i.e. Optical Electro-Chemistry response, and then study light-catalysed thermodynamics And dynamic process.
Summary of the invention
The technical problem to be solved is to provide a kind of nano-TiO2The preparation method of membrane electrode, it is provided that one Plant new synthetic method.
The synthetic method that the present invention uses, comprises the steps:
10mL butyl titanate is dissolved in 20mL dehydrated alcohol, then adds 3mL triethanolamine, add after being sufficiently stirred for 1h 2.4mL Polyethylene Glycol (PEG) 8000, continues stirring 2h, obtains homogeneous transparent colloidal sol, at tin indium oxide (ITO) electro-conductive glass table Topcoating film, is placed in wet film at 100 DEG C and is dried 5min, again carry out film and be dried；Put into Muffle furnace afterwards, with 5 DEG C/m The programming rate temperature programming of in, to 700 DEG C, naturally cools to room temperature after calcining 2h, obtain nano-TiO at 700 DEG C2Thin film Electrode.
The invention has the beneficial effects as follows: synthesis technique is simple, reaction condition is gentle, and production cost is relatively low, favorable repeatability.
Detailed description of the invention
Further illustrating present disclosure below in conjunction with example, as known by the technical knowledge, the present invention also can pass through other The scheme without departing from the technology of the present invention feature describe, the most all within the scope of the present invention or equivalent the scope of the invention in Change and be all included in the invention.
Embodiment:
10mL butyl titanate is dissolved in 20mL dehydrated alcohol, then adds 3mL triethanolamine, add after being sufficiently stirred for 1h 2.4mL Polyethylene Glycol (PEG) 8000, continues stirring 2h, obtains homogeneous transparent colloidal sol, at tin indium oxide (ITO) electro-conductive glass table Topcoating film, is placed in wet film at 100 DEG C and is dried 5min, again carry out film and be dried；Put into Muffle furnace afterwards, with 5 DEG C/m The programming rate temperature programming of in, to 700 DEG C, naturally cools to room temperature after calcining 2h, obtain nano-TiO at 700 DEG C2Thin film Electrode.
By experiment, thin film prepared by the inventive method is anatase crystal, and even particle size distribution, yardstick are suitable, and surface is deposited Shift at certain hole, beneficially mass transfer and electric charge.
