Synthesis of titania microspheres with hierarchical structures 0.25 mL of nonanoic acid was dropped into 20 mL of absolute alcohol and 80 uL of 0.1 mol/L KCl aqueous solution was added. After stirring for 15 min, 0.5 mL of tetra-n-butyl titanate was added under violently stirring. 5 min later, 1 mL of double distilled water was added. The milky white precursor microspheres suspension was kept static for 24 h and collected by centrifugation. The precursor microspheres were dispersed in an ethanol-aqueous solution. Then the suspension was sealed within a Teflon-lined autoclave (25 mL) and heated at 160 ¡ãC for 16 h. Following wash with ethanol three times, the precipitate was dried at 40 ¡ãC. The hydrothermal products were further calcined at 600 ¡ãC for 4 h to obtain the targeted products. ÏëÇëÎÊÆäÖеÄKClÆðµÄ×÷ÓÃÊÇʲô£¿Ð»Ð»£¡£¡ |
