【Abstract】 By sol-gel method and dip-coating technique,TiO2 particles were loaded to the surfaces of molecular sieve particles and porous Al2O3 beads,respectively.The XRD results indicated that TiO2 appeared on both supporting materials in anatase as nano-grade particle.Catalytic activities of the supported TiO2 photocatalysts were confirmed by degrading Rhodamine B in water.更多还原
