Abstract

The invention discloses a preparing method of an iron base bimetal hydroxide / pucherite photo-anode. The preparing method comprises the following steps that pucherite seed crystals are prepared; a pucherite photo-anode material is prepared through a hydrothermal method; and iron base bimetal hydroxide is deposited on the surface of the pucherite photo-anode through a rapid electrochemical deposition method, and accordingly an iron base bimetal hydroxide / pucherite photo-anode material is prepared. The invention further discloses application of the iron base bimetal hydroxide / pucherite photo-anode material to photoelectrocatalysis oxygen generation. The electro-deposition method is adopted for preparing the iron base bimetal hydroxide / pucherite photo-anode material, and the beneficial effects that the process is simple, spent time is short, and the metal proportion can be regulated and controlled are achieved. The iron base bimetal hydroxide can serve as an oxygen generation promoter and has the character of visible light response, an interface structure can be formed between the iron base bimetal hydroxide and pucherite, accordingly, generation of the water oxidation reaction is promoted, and accordingly the photoelectric catalysis oxygen generation performance is enhanced.

Description

technical field

[0001] The invention relates to the field, in particular to a preparation method and application of an iron-based double metal hydroxide / bismuth vanadate photoanode. Background technique

[0002] Severe environmental pollution and huge energy consumption caused by the rapid development of the world economy have become major problems to be solved urgently in all countries, which are also the primary issues related to the survival and development of human beings. Many problems caused by energy shortage and environmental pollution make countries all over the world eager to find renewable, efficient and clean new energy sources.

[0003] As a new energy source, solar energy radiates about 4.3×10 20 joules per day, more than the total energy consumption of the earth in one year. Solar energy can split water into H 2 and O 2 , the photolysis of water contains two half-reactions: reduction and oxidation of water; the oxidation of water involves a multi-step four...
