specific Embodiment approach 1

[0101] Specific embodiment one: this embodiment is a kind of TiO 2 The surface of the anode supports Co 3 o 4 The method is done in the following steps:

[0102] 1. Preparation of TiO 2 Slurry: TiO 2The powder, terpineol and ethyl cellulose are added to absolute ethanol, then stirred at a stirring speed of 300r / min to 400r / min for 2 days to 3 days, and then aged at room temperature for 2 days to 3 days to obtain TiO 2 slurry;

[0103] TiO as described in step 1 2 The mass ratio of powder to terpineol is 1:(4.5~4.7);

[0104] TiO as described in step 1 2 The mass ratio of powder to ethyl cellulose is 1:(0.26~0.28);

[0105] TiO as described in step 1 2 The mass ratio of powder to absolute ethanol is 1:(0.9~1);

[0106] 2. Prepare the anode:

[0107] Cut the FTO conductive glass to obtain FTO conductive glass with a size of 1.5cm×2.5cm; respectively use acetone, ethanol and deionized water to ultrasonically clean the FTO conductive glass with a size of 1.5cm×2.5cm fo...

Abstract

The invention discloses a method for loading the surface of a TiO2 anode with Co3O4, and relates to the method for loading the surface of the anode with Co3O4. The invention aims to solve the problems that an anode used in a conventional water decomposition device is a noble metal catalyst, the method is complex, the cost is high and the anode cannot be generally applied. The method comprises the steps: 1, preparing a TiO2 slurry; 2, preparing an anode; 3, coating; 4, preparing FTO conductive glass loaded with a TiO2 blank piece; 5, preparing a TiO2 anode; 6, preparing a photosensitizer; 7, preparing a cleaned TiO2 anode having the surface loaded with the photosensitizer; 8, preparing Co3O4 nanoparticles; 9, preparing a Co3O4 dispersion liquid; 10, preparing a Co3O4 catalyst-containing dye-sensitized TiO2 photoanode; 11, synthesizing a biomimetic redox couple; and 12, impregnating, and thus obtaining the TiO2 anode having the surface loaded with Co3O4. The method for loading the surface of the TiO2 anode with Co3O4 can be obtained.

Description

technical field [0001] The invention relates to an anode surface loaded Co 3 o 4 Methods. Background technique [0002] With the continuous progress of human society, the demand for energy, as the material basis for promoting social development, is increasing day by day, and the ensuing environmental problems are also becoming more and more serious. Hydrogen energy is considered to be one of the most ideal energy sources in the new century due to its high energy content, green environmental protection and other advantages. In 1972, Japanese scientist Fujishima first discovered the possibility of using solar energy as the initial energy to directly decompose water to produce hydrogen. Afterwards, scientists were inspired by the natural photosynthesis system II (referred to as photosystem II) and simulated it, opening up a new field of using visible light to split water. Water splitting consists of two reactions: water oxidation and proton reduction, and the water oxidatio...
