High-value-added utilization of heavy-metal-containing waste is important for the sustainable development because most resources are non-renewable. In this work, an effective catalyst for volatile organic compounds was synthesized from manganese slag. Furthermore, the powder catalyst was coated on cordierite, and the obtained monolithic catalyst (0.6 m³) was applied in a real application. As a result, the powder catalyst removed 90% of toluene at 300°C; the monolithic catalyst removed 98% of real volatile organic compounds at 350°C. The activity was only decreased to 84% even after 10-month running. After characterizations, a manganese-oxygen bond was recognized for the enhanced catalytic activity. The decrease of activity was due to the loss of this bond, which was attributed to local overheating during oxidization of volatile organic compounds. After all, the main results of this work helped to produce effective catalysts from low-cost materials, which was in favor of recycling economy and green development.

含重金属废物的高附加值利用对于可持续发展具有重要意义，因为大多数资源是不可再生的。在这项工作中，以锰渣为原料合成了一种有效的挥发性有机化合物催化剂。进一步将粉体催化剂包覆在堇青石上，得到整体催化剂（0.6 m ³) 已应用于实际应用程序中。结果，粉末催化剂在 300°C 下去除了 90% 的甲苯；整体催化剂在 350°C 下去除了 98% 的真正挥发性有机化合物。即使在运行 10 个月后，活动率也仅下降到 84%。表征后，发现锰-氧键具有增强的催化活性。活性降低是由于这种键的丢失，这是由于挥发性有机化合物氧化过程中局部过热造成的。毕竟，这项工作的主要成果有助于用低成本材料生产有效的催化剂，有利于循环经济和绿色发展。
