Summary: As an emerging class of nanoporous materials, Metal Organic Framework (MOFs) have attracted attention for their advantages in environmental remediation. ZIFs and Ni-MOF were chosen as fluoride (F-) scavengers due to their robust structures and straightforward synthesis routes. The relationship between F- adsorption and the geometry and structural properties of ZIFs was studied. Using the Box-Behnken design (BBD), the key operating variables such as pH, mixing time, F -concentration, and ZIF-67-NO3 dose were modeled. Optimization of the model achieved a maximum 85.9% F- removal under specific conditions.

Summary: In this work, porous Co3O4 was prepared by controlled calcination of zeolite imidazole framework-67 (ZIF-67) precursor template, and CeO2/Co3O4 composites with a porous framework structure were prepared by hydrothermal methods. The porous structure of Co3O4 prevented the aggregation of CeO2 nanoparticles and enabled their uniform dispersion on the surface. CeO2 introduction led to changes in the specific surface area and pore size of Co3O4, resulting in better binding and achieving good catalytic performance. CeO2/Co3O4 modification on glassy carbon electrodes (GCE) exhibited superior electrocatalytic activity compared to pure Co3O4 and CeO2. The CeO2/Co3O4/GCE demonstrated a detection limit of 0.13 μM for dopamine (DA) and a linear range of 0.13 μM-60 μM, with good interference resistance and reproducibility. This work provides a new solution for excellent dopamine sensors using Co3O4 and CeO2 composites, which can be extended to other biosensing applications.

Summary: Developing efficient and low-cost photocatalysts for CO2 reduction is crucial for converting CO2 into valuable chemicals. In this study, a Co-based zeolitic imidazole framework (ZIF-67) photocatalyst doped with dicyandiamide (DCD) and a trace amount of Ru cocatalyst exhibited exceptional photocatalytic activity for CO2 reduction. The strong orbital coupling in the ZIF-67DCD-Ru structure facilitated strong CO2 adsorption, electron enrichment on the cocatalyst, and minimized Gibbs free energy barrier for CO generation. The synthesized ZIF-67/DCD/Ru sample showed excellent CO2 photoreduction performance, achieving a record-breaking turnover frequency (TOF) of 151 h-1 among all reported ZIF-based photocatalysts. This work provides a novel approach for achieving high activity in ultra-low noble metal loading photocatalysts and advances our understanding of the series structure.

Summary: Based on two different topologies of MOFs, core-shell bimetallic MIL-101/ZIF-67(x) (M/Z(x)) materials were successfully synthesized for the activation of peroxymonosulfate (PMS) self-decomposition in order to degrade 2-chlorophenol. The M/Z(x) exhibited not only the advantages of single-metal MOFs such as high surface area and pore volume, but also superior catalytic performance. Further investigation revealed that the catalytic degradation of 2-chlorophenol was promoted by the synergistic effect of cobalt and iron active sites in M/Z(x), which enhanced the Co2+/Co3+ redox cycle. Radical and non-radical pathways contributed to the degradation, with singlet oxygen (O-1(2)) playing a predominant role in the non-radical pathway. Sulfate radical (SO4 center dot-) and hydroxyl radical ((OH)-O-center dot) also accelerated the degradation process.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
