The invention discloses a tetrahydroxy
phthalocyanine zinc-reduced
graphene oxide nano-composite as well as an electrochemical sensor prepared from the tetrahydroxy
phthalocyanine zinc-reduced
graphene oxide nano-composite and application of the tetrahydroxy
phthalocyanine zinc-reduced
graphene oxide nano-composite. The tetrahydroxy
zinc phthalocyanine-reduced graphene oxide nano composite is formed by combining water-soluble tetrahydroxy
zinc phthalocyanine and reduced graphene oxide large pi bonds through non-covalent bonds. The combination of the two improves the
disadvantage of poor dispersibility of the two while giving consideration to the advantages of the two, and has the advantages of large specific surface area, good
conductivity, strong stability, easy availability, no toxicityand environmental friendliness. The
Nafion tetrahydroxy phthalocyanine zinc-reduced graphene oxide
nanocomposite is directly coated on the surface of a
glassy carbon electrode through a one-step dispensing method, and the method has the advantages of being rapid and simple to operate, good in reproducibility and the like. The prepared sensor is low in cost, good in stability and selectivity, capable of achieving accurate, rapid and high-sensitivity detection of
acetaminophen and wide in detection range, the
detection limit is as low as 10 nmol / L, and the sensor has potential application valuein the fields of
clinical diagnosis,
drug analysis and the like.
