Preparation and performance optimization of Co-doped high-titanium blast furnace slag as photocatalytic material

  • 摘要: 为了实现以非提钛方法对高钛型高炉渣的综合利用,利用其含TiO2可制备光催化剂的特点,以攀钢高钛型高炉渣掺杂硝酸钴为原料,采用液相法掺杂并烧结制备掺杂Co的光催化剂,在紫外光下,考察了煅烧温度、掺杂量及煅烧时间对模拟污染物亚甲基蓝溶液降解率的影响。结果表明:在煅烧温度600 ℃、Co-Ti质量掺杂比(w(Co): w(Ti))0.03、煅烧时间2 h时,制备的掺杂Co光催化剂降解率达到89.0%,比未掺杂之前提高了32.4%。
