specific Embodiment approach 1

[0104] Specific implementation mode 1: This implementation mode is a water splitting device made of Co 3 o 4 Modified photoanode 1, cathode 2, first wire 4, second wire 5, power supply 3 and tank 6 with water; the Co 3 o 4 The modified photoanode 1 and cathode 2 are set in a tank 6 filled with water, Co 3 o 4 The modified photoanode 1 is connected to the positive pole of the power supply 3 through the first wire 4, as the anode of the water splitting device; the cathode 2 is connected to the negative pole of the power supply 3 through the second wire 5, as the cathode of the water splitting device;

[0105] The Co 3 o 4 Modified photoanode 1 was prepared as follows:

[0106] 1. Preparation of TiO 2 Slurry: TiO 2 The 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;

[0107] TiO as described i...

specific Embodiment approach 2

[0193] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the cathode 2 is a platinum wire. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0194] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the power supply 3 is a DC power supply of 0.3VvsAg / AgCl. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a water splitting device, relates to water splitting equipment, and aims to solve the problems that an existing water splitting device is high in cost, and the synergy effect of a catalyst in a used anode and a photosensitizer is poor. The water splitting device consists of a Co3O4 modified photo-anode, a cathode, a first wire, a second wire, a power supply and a water tank containing water, wherein the Co3O4 modified photo-anode and the cathode are arranged in the water tank containing the water; the Co3O4 modified photo-anode is connected with a positive pole of the power supply through the first wire and serves as an anode of the water splitting device; and the cathode is connected with a negative pole of the power supply through the second wire, and serves as a cathode of the water splitting device. The water oxidation efficiency of the water splitting device is 3%-5%. Compared with an existing water splitting device, the water splitting device has lower cost reduced by 99.6%-99.8%. By the invention, the water splitting device can be obtained.

Description

technical field [0001] The invention relates to a water splitting device. 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 oxidation reaction is the ...
