Two Novel Self-Catenated Metal–Organic Frameworks with Large Accessible Channels Obtained by a Mixed-Ligand Strategy: Adsorption of Dichromate and Ln³⁺ Postsynthetic Modification

Two novel metal–organic frameworks, namely [Cd3(bdc)­(HCOO)2(tipo)2(H2O)2]·2NO3·6DMF (1) and [Zn8(OH)4(bpdc)6(tipo)4]·16DMF (2) (tipo = tris­[4-(1H-imidazol-1-yl)­phenyl]­phosphine oxide, H2bdc = phenyl-1,4-dicarboxylic acid, H2bpdc = biphenyl-4,4′-dicarboxylic acid), have been successfully synthesized. Compound 1 exhibits a cationic 4,6-connected self-catenated framework with large 1D channels. Compound 2 features a 3,4-connected self-catenated framework with potential O donors located on the surface of the channels. Compound 1 shows a high adsorption for dichromate. Postsynthetic modification of 2 by lanthanide ions (Eu3+ and Tb3+) afforded fluorescent materials

In Situ Growth of Nitrogen-Doped Carbon Nanotubes Based on Hierarchical Ni@C Microspheres for High Efficiency Bisphenol A Removal through Peroxymonosulfate Activation

N-doped carbon nanotubes (NCNTs) are promising metal-free heterogeneous catalysts toward peroxymonosulfate (PMS) activation in advanced oxidation processes for wastewater remediation. However, conventional CNTs always suffer from serious agglomeration and low N content, which renders their design synthesis as an important topic in the related field. With hierarchical Ni@C microspheres as a nutritious platform, we have successfully induced in situ growth of NCNTs on their surface by feeding melamine under high-temperature inert atmospheres. These as-grown NCNTs with a small diameter (ca. 20 nm) are firmly rooted in Ni@C microspheres and present loose accumulation on their surface, and their relative content can be tailored easily by manipulating the mass ratio of melamine to Ni@C microspheres. The investigation on bisphenol A (BPA) removal reveals that the loading amount of NCNTs affects the catalytic performance greatly, and the optimum ratio of melamine to Ni@C microspheres is 5.0 because the corresponding MNC-5.0 possesses sufficient surface N sites and moderate electron transfer, resulting in powerful PMS activation and sufficient utilization of reactive oxidative species (ROS). MNC-5.0 also addresses its advantages as compared with other NCNTs from post treatment and spontaneous growth strategies. The primary ROS responsible for BPA degradation are identified as hydroxyl radical, sulfate radical, superoxide radical, and singlet oxygen through quenching experiments and electron paramagnetic resonance, and the corresponding catalytic mechanism is also put forward based on these results

Construction of a Dual-Function Metal–Organic Framework: Detection of Fe³⁺, Cu²⁺, Nitroaromatic Explosives, and a High Second-Harmonic Generation Response

In this work, an Eu3+-based dual-function metal–organic framework [Eu2L2(DMF)­(H2O)2]·2DMF·H2O [H3L = 5-(1-carboxynaphthalen-4-yl)­benzene-1,3-dioic acid] (1) has been successfully constructed. This compound can effectively detect Cu2+, Fe3+, and 4-nitrophenol with low detection limits of 18.3, 12.2, and 3.63 ppm, respectively. It also displays a high second-harmonic generation response ca. 2.0 times that of KH2PO4
