Claim 0:
1. A method for preparing organic-inorganic hybrid nanoflower by electrodeposition, comprising the following steps:
(a) mixing an aqueous solution of a rare earth nitrate with a biological enzyme and a nitrate to obtain a mixed solution; the rare earth ions in the rare earth nitrate are one or more selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb and Y ions; the biological enzyme is α-amylase, horseradish peroxidase or laccase;
(b) electrodepositing the mixed solution obtained in step (1) with a three-electrode system consisting of a working electrode, a counter electrode and a reference electrode to obtain an electrodeposited film on the surface of the working electrode; the electrodeposition is a constant voltage deposition, and the deposition voltage is −0.8 to −1.3 v;
(c) washing and drying the electrodeposited film successively to obtain organic-inorganic hybrid nanoflower.
