| Abstract | Higher efficient degradation of methyl orange (MO) was demonstrated with nanometer-sized high-silica SAPO-5. By a hydrothermal process, synthesized high-silica SAPO-5 and low-silica SAPO-5 showed Si-to-Al ratios of 4.20 and 0.11, respectively. High-silica SAPO-5 showed much better MO degradation efficiency with a dosage of 70mg in MO solution with a concentration of 10mg/L under ultraviolet illumination. High-silica SAPO-5 also exhibited good producibility for preparation and stable photocatalytic activity even after the fifth recycling test. Optical characterizations of DRS, XPS, photocurrent density and time-resolved fluorescence were carried out for SAPO-5 samples. Finally, free radical and hole scavenging experiments were investigated for high-silica SAPO-5, and a MO photodegradation mechanism based on the charge transfer excited state of [Al2+-O-]* was proposed. This work highlights great prospects of high-silica SAPO-5 for organic pollutant removal with virtues of ideal efficiency and environmental friendliness. |
