Summary: This study proposes a simple isolation method for extracting fluorescent fraction from the surface-adhered waste of pollutant diesel soot, which is further separated using gel-separation technique to obtain highly fluorescent water-soluble nano-carbons. The as-extracted blue-green fluorescent water-soluble fraction shows strong fluorescence photostability and is used for selective sensing of Fe(iii) and toxic-Hg(ii) metal ions among others, with Fe(iii) quenching attributed to inner filter effect mechanism and Hg(ii) quenching to ligand to metal charge transfer mechanism.

Summary: This paper proposes a simple strategy to effectively adsorb anionic dyes by adding graphene oxide (GO) to a metal-organic framework (MOF) called MIL-101. The maximum adsorption uptakes of this MIL-101@GO composite material for Congo red, o-cresolsulfonphthalein, and methyl orange are significantly higher than that of the original MIL-101 due to additional factors such as hydrogen bonding and the presence of agglomerate pores. However, the maximum adsorption uptake for acid chrome blue K is lower than that of MIL-101 due to steric hindrance.

Summary: Developing multifunctional metal-organic frameworks (MOFs) is a new research trend. MOFs have shown remarkable performances in both proton conduction and fluorescence sensing, but the MOFs integrating the two performances are scarce. In this study, a Co-MOF [Co-6(oba)(4)(Hatz)(atz)(H2O)(2)(mu(3)-OH)(2)(mu(2)-OH)].H2O (1) was assembled, which provides a unique example of multifunctional MOFs with both proton conduction and fluorescence sensing performances. The framework of 1 displays a pillar-layer structure built by the oba ligand as a pillar and a layer composed of Co-clusters and atz linkers. The proton conduction ability and fluorescence sensing of 1 were studied, showing highly anisotropic conduction and selective detection of Fe3+ ions.

Summary: Metal-organic framework (MOF) materials show remarkable performance in gas separation, but it is challenging to obtain materials with high gas capacity and selectivity simultaneously. In this study, MOF-801-(Zr/Ce/Hf) was created based on the green synthesis of the MOF-801 construction unit, and the impact of three metal nodes on gas adsorption and separation performance was demonstrated. The results showed that MOF-801-(Ce) had the best CO2 adsorption capacity and excellent separation performance in CO2/CH4 and CO2/N-2 systems.

Summary: A general approach to prepare superhydrophobic MOFs-CF3 through a post-decorating strategy for highly efficient chemical fixation of CO2 was demonstrated. The enhanced catalytic activity of MOFs-CF3 is attributed to a synergistic effect between the Lewis acid sites of MOFs and modification of the electron-withdrawing trifluoromethyl group, resulting in a high CO2 enrichment capacity. The possible mechanism of cycloaddition catalyzed by the MOFs-CF3 catalyst was also proposed.
