Article Abstract
Doxorubicin (DOX) has been an emerging environmental pollutant due to its significant genotoxicity to mankind. Advanced oxidation processes are a potential strategy to remove DOX in water solution. To develop a highly efficient catalytic agent to remove DOX, bimetal MOFs were synthesized, with Cu and Co as the central ions and adenine as the organic ligand. This study investigated the degradation of DOX by Co/Cu-MOFs combined with peroxymonosulfate (PMS). It was found that the degradation of DOX by Co/Cu-MOFs can reach 80% in only 10 seconds. This can be explained by the charge transfer from Co(iii) to Co(ii) being accelerated by Cu, resulting in the rapid generation of free radicals, which was proved by the EIS Nyquist diagram. Co/Cu-MOFs can be reused by simply washing with water without inactivation. Therefore, Co/Cu-MOFs can be used as an efficient catalytic agent to degrade DOX in environmental water.

Three-dimensional hierarchically structured ZnCoO/ZnO (ZnCoO) composites have been prepared through a simple thermal treatment of ZnCo-bimetal MOF (ZnCo-MOF) precursors. We found that the solvothermal reaction temperature for preparing ZnCo-MOFs has an important influence on the composition and structure of the ZnCoO composites. When the temperature is 100 °C, ZnCoO-100 and ZnCoO-100-P (PVP added) present well-defined hierarchical cubic structures composed of loosely packed nanoplates and nanorods, in which ZnO is the major component.

In this study, the novel composite material was synthesized by loading Mn-doped Fe-based gallic acid metal-organic frameworks (MOFs) onto biomass cotton fibers (Mn/Fe-GA-MOFs@CF). Mn doping improved the catalytic efficiency of Fenton-like reactions. Moreover, the MOFs loading onto cotton fibers enhanced the recoverability and practical usability.

To address the issues of poor Co regeneration and limited interfacial electron transfer in heterogeneous catalytic systems, this study proposes the synthesis of highly efficient and stable CoO/ZnO composites through the pyrolysis-oxidation reaction of Co/Zn MOFs for the degradation of rhodamine B (RhB) using activated peroxymonosulfate (PMS). The results confirmed that the catalyst exhibited a high electron transfer capacity, and the synergistic effect between the bimetals enhanced the reversible redox cycle of Co/Co. Under optimal conditions, complete removal of RhB was achieved in just 6 min using the CoO/ZnO composite, which demonstrated excellent stability after five cycles.

Developing efficient and durable non-precious metal catalysts for oxygen electrocatalysis in fuel cells and zinc-air batteries remains an urgent issue to be addressed. Herein, a bimetallic CoCe-NC catalyst is synthesized through pyrolysis of Co/Ce co-doped metal-organic frameworks (MOFs), retaining the inherently high surface area of MOFs to maximize the exposure of Co-N and Ce-N active sites. The electronic interaction between Co and Ce atoms effectively modulates the adsorption/desorption behavior of oxygen-containing intermediates, thereby enhancing intrinsic catalytic activity.

Metal-organic frameworks (MOFs) such as ZIF-67 have been widely studied. Incorporating multi-bimetals into ZIF-67 is a strategic approach to leverage unique properties and address the limitations of traditional single metals in ZIF-67. Herein, an environmentally friendly solid-solid thermal (SST) method is developed to simultaneously incorporate heterometals (Cu, Fe, Ru, Pd, Mn, and Ni) into the ZIF structure, referred to as M@ZIF-67.
