以自制竹炭为载体、仲钨酸铵为钨源,采用微波辅助溶胶-凝胶法制备了ZnWO4/竹炭复合材料。用TG,SEM,BET等分析技术对其进行了表征,并就其对罗丹明B的光降解催化作用进行了研究。结果表明:在微波功率640 W,时间10 min,400℃条件下的空气中焙烧所制备的ZnWO4/竹炭复合材料,当竹炭含量为20%时,具有较好的紫外光催化活性。

ZnWO4/bamboo charcoal (ZW/BC)photocatalysts were synthesized by the microwave assisted sol-gel method with 5(NH4)2·12WO3·5H2O as the W source,and bamboo charcoal as the support.The structured features of these materials were analyzed by TG,while their morphologies were characterized by SEM and BET.High efficiency for the degradation of Rhodamine B (RhB)under both UV light was ob-tained for the ZW/BC photocatalysts.The results indicated that the composites with 20%(wt)bamboo charcoal sintered in air at 400 ℃for 10 min in microwave power 640 W charactered had the better photo-catalytic ability in the UV light.
