摘　　要：以葡萄糖为原料,采用水热法合成纳米碳球。合成的碳球用硝酸进行处理,然后用磷钨酸进行附载,制备了碳球负载磷钨酸复合材料。采用IR、SEM技术对材料进行表征,同时研究了样品光催化降解亚甲基蓝(MB)溶液的效能。研究显示,碳球负载磷钨酸作为催化剂降解10 mg/L的亚甲基蓝溶液,经过180 min的反应后,亚甲基蓝的降解率达到92%,明显的高于纯磷钨酸做催化剂的20%。The paper mainly uses glucose as raw material, adopts the method of hydrothermal synthesis of nanometer carbon ball. Synthesis of carbon ball was treated with nitric acid, and then loaded with phosphotungstic acid. The synthetic samples were characterized by IR and SEM technologies, and the photocatalytic reaction of carbon ball supported phosphotungstic acid was used as catalyst for degradation of methylene blue （MB） solution 10 mg/L, the degradation rate was 92 % after 180 rain irradiation, which was better than that of pure phosphotungstic acid with 20 %.
