▎ 摘  要

NOVELTY - Catalyzing and degrading methyl orange involves dispersing graphene oxide into 50-500 mg/L solution to obtain mixed solution, ultrasonic stirring for 30 minutes, transferring 100-300 ml mixed solution to 45-60 degrees C in constant temperature water bath under the action of magnetic stirring. The 15-20 % titanium chloride solution, 0.05 ml drops of nonyl phenol polyoxyethylene ether ammonium halide surfactant are added, reacted for 120 minutes, and cooled the mixture. The mixture is placed into a hydrothermal reaction kettle at 150-180 degrees C in calcining box for 8-10 hours, naturally cooled, centrifuged, and washed by distilled water, absolute ethyl alcohol for 2-3 times. The washed product is dried at 80-90 degrees C in oven to obtain solid powder which graphene oxide/titanium oxide composite material. The 0.1-1 g graphene oxide/titanium oxide composite material is placed in 100 mL of methyl orange solution, ultrasonically processed for 30 minutes, and stirred for 30 minutes. USE - Method for catalyzing and degrading methyl orange. ADVANTAGE - The method enables to catalyze and degrade methyl orange that has low cost, low energy consumption and no secondary pollution. DETAILED DESCRIPTION - The 1-3 mL of hydrogen peroxide is added into mixed solution, placed away from the light source to 6 cm, and irradiated for degrading methyl orange.
