摘要
A novel PTA/ZIF‐8@CA composite material (PTA = phosphotungstic acid; CA = cellulose aerogel) with multilayer three‐dimensional network structure was synthesized with cellulose aerogel as the framework and MOFs as the filler. The results showed that the degradation rates of methylene blue at δ = 10 ppm reached 99.8 % respectively in 30 min under the conditions of PTA/ZIF‐8@CA input amount of 0.6 g · L –1 and pH = 5. The degradation rate of rhodamine B at δ = 10 ppm reached 99.7 % in 60 min. This shows that PTA/ZIF‐8@CA has excellent degradation efficiency and short‐term performance. In addition, after 5 photocatalytic cycles, the degradation rates of methylene blue and rhodamine B by PTA/ZIF‐8@CA were still 83.0 % and 82.5 %, respectively, reflecting that PTA/ZIF‐8@CA has terrific photocatalysis stability.
