Benefited from developed pore structure and synergistic effect with MOFs, the porous carbon not only provides a stable carrier for MOFs but also serves as a buffer for organic pollutants to promote removal of malachite green (MG). Herein, a bimetallic CoFe-MOF was anchored successfully on bamboo pulp black liquor (BPBL)-derived porous carbon (PC) by hydrothermal method, and then PC loaded with elemental and oxide of cobalt and iron was acquired through high-temperature pyrolysis. Adsorption capacity of the prepared CoFe/PC on MG can reach 1894 mg/g; additionally, catalytic degradation efficiency of MG reached 98.9% within 28 min. The loading of Co and Fe oxides enhances adsorption properties of PC for MG, and synergistic effect of Co and Fe elements and the synergistic effect of MOFs and PC also improves degradation efficiency of CoFe/PC for MG. Additionally, loading of Co and Fe provides magnetic properties for PC, which is convenient for recovery. These results indicate that the combination of bimetallic MOFs and porous carbon supplies an alternative for MG removal.

得益于发达的孔结构和与 MOFs 的协同作用，多孔碳不仅为 MOFs 提供了稳定的载体，而且还作为有机污染物的缓冲剂，促进孔雀石绿 (MG) 的去除。在此，通过水热法成功地将双金属 CoFe-MOF 固定在竹浆黑液 (BPBL) 衍生的多孔碳 (PC) 上，然后通过高温热解获得负载有钴和铁的元素和氧化物的 PC。制备的CoFe/PC对MG的吸附量可达1894 mg/g；此外，MG的催化降解效率在28分钟内达到98.9%。Co和Fe氧化物的负载增强了PC对MG的吸附性能，Co和Fe元素的协同​​作用以及MOFs和PC的协同作用也提高了CoFe/PC对MG的降解效率。此外，Co和Fe的负载为PC提供了磁性，便于回收。这些结果表明，双金属 MOF 和多孔碳的组合提供了一种去除 MG 的替代方法。
