Method for preparing plasma gold nanorod composite photocatalytic material with butterfly wing structure

Abstract

The invention discloses a method for preparing a multielemnt metal oxide-loaded plasma gold nanorod composite photocatalytic material with a grading structure by a butterfly wing structure. The method mainly comprises the following steps of pretreating butterfly wings; respectively and sufficiently dissolving salt compounds of metals A and B into organic solvents, and uniformly mixing the two types of organic solvents, wherein the metal A is one of metal Bi (bismuth), Sr (strontium), Ca (calcium), Pb (plumbum), Li (lithium), Na (sodium) and K (potassium); the metal B is one of metal V (vanadium), Ti (titanium) and Ta (tantalum); soaking a butterfly wing template into the prepared mixed solution, and insulating the temperature; fetching out the butterfly wing template, cleaning, and drying; insulating the temperature of the butterfly wing template for 5-10h at the temperature of 500-600 DEG C; utilizing a seed growth method to prepare a gold nanorod; loading the gold nanorod onto the multielement metal oxide material by an improved primary wetting method. The prepared composite photocatalytic material system has the advantage that the photocatalytic property is obviously improved.

Description

technical field

[0001] The invention relates to a preparation method of a multi-element metal oxide-loaded plasma metal nanostructure composite photocatalytic material, in particular to a preparation method of a multi-element metal oxide-loaded plasma gold nanorod composite photocatalyst material prepared by using a butterfly-wing template method. Background technique

[0002] Energy and the environment are major issues facing and urgently to be resolved in the 21st century. Photocatalytic materials can destroy many structurally stable refractory organic pollutants, reduce heavy metal ions, deodorize, preserve and sterilize. Compared with traditional water treatment technology, it has the advantages of energy saving, high efficiency, complete pollutant degradation and no secondary It has become an environmental pollution control method with important application prospects. Traditional photocatalytic materials have the disadvantages of narrow photoresponse range and low qua...
