Abstract

The invention relates to a ball-flower-shaped Co3(PO4)2 / chloroperoxidase hybridized nanoreactor and an application thereof. The ball-flower-shaped Co3(PO4)2 / chloroperoxidase hybridized nanoreactor, which is relatively small in diameter, relatively good in compactness and stable in structure, can be obtained through adding chloroperoxidase and cobalt acetate into a phosphate buffer solution with the pH value of 3 to 6, standing the obtained mixed solution, removing supernatant, and carrying out vacuum drying. A preparation method of the ball-flower-shaped Co3(PO4)2 / chloroperoxidase hybridized nanoreactor is simple, and the prepared ball-flower-shaped Co3(PO4)2 / chloroperoxidase hybridized nanoreactor is good in thermal stability and high in tolerance to reaction environments; the total amount of the chloroperoxidase exposed to surface is relatively large, so that the area of contact of the chloroperoxidase with a substrate during reaction is increased; during the degradation of triphenylmethane water-soluble dyes, relatively high catalytic activity is shown, and the rate of degradation to crystal violet in five minutes can reach 80% or more, so that the ball-flower-shaped Co3(PO4)2 / chloroperoxidase hybridized nanoreactor has a relatively good application prospect.

Description

technical field

[0001] The invention belongs to the technical field of enzyme immobilization, in particular to a Co 3 (PO 4 ) 2 / Chloroperoxidase hybrid nanoreactor and its synthesis method and its application in catalytic degradation of triphenylmethane water-soluble dye crystal violet. Background technique

[0002] Enzymatic reactions have many advantages, such as: mild reaction conditions (normal temperature and pressure and pH close to physiological conditions), fast reaction, good selectivity, etc., and can avoid complex functional group protection or activation steps in organic reactions, so It is more efficient, more economical and greener than general organic synthesis. However, despite the above advantages, the large-scale industrialization of the enzyme is due to the poor stability of the enzyme for a long time in the actual reaction environment such as high temperature, strong acid and strong alkali, and the presence of organic solvents, and it is difficult to ...
