Disclosed is an application of a hydrophobic phthalocyanine as a heterogeneous catalyst in oxidizing phenol wastewater by hydrogen peroxide. A hydrophobic silane is decorated on a bacterial cellulose-metal phthalocyanine heterogeneous catalyst to obtain a hydrophobic phthalocyanine heterogeneous catalyst; during the catalytic degradation of phenols, the obtained catalyst is capable of adjusting a concentration of hydrogen peroxide oxidant around the catalyst. A preparation method of the hydrophobic phthalocyanine comprises: 1. preparing a mixed solution of a bacterial cellulose medium containing metal phthalocyanine; 2. adding acetic acid bacterium into the mixed solution obtained in step 1 for biological culture; 3. heating the product obtained in step 2, and taking out a solid for cleaning and drying; 4. preparing a hydrophobic silane solution; and 5. immersing the product obtained in step 3 into the solution obtained in step 4, and taking out a solid after reaction for cleaning and drying.
