【摘要】 以CuO和Cu₂O为原料混合制得CuO/Cu₂O粉体作为光催化剂。结果表明,用太阳光作为光源照射4 h,溶液的酸度为pH8,CuO/Cu₂O的用量为40mg/50mL,靛兰二磺酸钠、罗丹明B等染料脱色率达到90%以上。加入Fe³⁺、H₂O₂等其他物质可提高染料的脱色率。通过紫外可见光谱分析,表明染料分子在催化剂和光照条件下发生了降解。CuO/Cu₂O简单处理后可以重复使用。更多还原

【Abstract】 Ultrafine powder CuO/Cu₂O photocatalysts were prepared by CuO and CU₂O mixture. After irradiation with sun light for 4 h,the decoloration rate was up to 90%when the concentration of dyes was 20mg/L,the amount of catalyst was 40mg and the acidity was pH8 in 50mL dye solution.Adding Fe³⁺、H₂O₂ and other catalyst can improve the decoloration rate greatly.So the decoloration of dyes was due to photocatalytic degradation by analyzed the Ultraviolet spectrum, and the photocatalytic activity of CuO/Cu₂O powder is good in photocatalytic decoloration of dyes, such as indigo carmine、rhodamine B and so on.The stability of photocatalytic nature of powder CuO/Cu₂O was studied,and CuO/Cu₂O powder can be recycled.更多还原
