Abstract

The invention relates to the fields of nanomaterials, catalysis and analytical chemistry, in particular to a preparation method for synthesizing a manganese dioxide nanowire on the basis of using filamentous phage as a biological template and the application of the manganese dioxide nanowire in catalysis aspect. The method comprises the following steps: mixing the filamentous phage with manganous ions by using inherent nanostructure characteristics of the filamentous phage and properties of capsid protein of the filamentous phage; adding sodium hydroxide and carrying out normal temperature reaction to generate manganese dioxide on the surface of the filamentous phage, namely obtaining the manganese dioxide nanowire with the diameter of 10 to 50nm. The material has the biomimetic catalytic characteristic and electrochemical catalysis characteristic, so that the material has a broad application prospect in the fields of analytical chemistry, capacitors and catalysis. According to the method, a natural nanobiological structure is used as a template; the method has the advantages of simple preparation process, mild and environment-friendly reaction conditions and easily-controlled nanostructure.
