Research Abstract	Horseradish peroxidase is one of the important enzymes for phenol oxidation, but it has not phenol oxidation ability in the acidic conditions. Then, new artificial enzymes (biomimetic catalysts) were prepared by the introduction of active-site structure of HRP to cellulose and chitosan, which are main chemical component of wood and crab shell, respectively. They had good phenol oxidation abilities in the acidic conditions and photo-current generation abilities.
