摘　　要：以Bi(NO)_(3)和KCl作为原料,采用水解-煅烧法合成了层状Bi_(12)O_(17)Cl_(2)光催化材料。通过XRD、SEM等手段研究了不同合成条件对样品晶形结构和形貌的影响,结果表明,Bi_(12)O_(17)Cl_(2)的形貌受到乙酸浓度、pH值和煅烧温度的影响。以盐酸四环素为目标物,探究了层状Bi_(12)O_(17)Cl_(2)光催化降解性能,在乙酸浓度为33%、pH=6时,400℃下煅烧2 h合成的Bi_(12)O_(17)Cl_(2)在30 min内可见光照射下,对盐酸四环素的降解效率达到81.67%。Herein,a layered Bi_(12)O_(17)Cl_(2)photocatalyst was synthesized through a hydrolysis and calcination route by using Bi(NO)_(3)and KCl as raw materials.The crystal structure and morphology of the samples under different synthetic conditions were characterized by X-ray powder diffraction XRD and scanning electron microscopy(SEM).The results indicated that the crystal phase and morphology of Bi_(12)O_(17)Cl_(2)photocatalyst were significantly affected by acetic acid concentrations,pH values,and calcination temperatures.Furthermore,for the optimized Bi_(12)O_(17)Cl_(2)prepared at 400°C of calcination temperature,33%of acetic acid concentration and pH=6 by using NaOH as pH adjuster,the degradation efficiency of tetracycline hydrochloride for 30min could reach 81.67%within 30 min under visible light irradiation.
