Summary: By utilizing dual organic structure-directing agents to recrystallize the binder (silica)/Ti-MWW extrudates, the silica binder was converted into MWW zeolite phase to form a structured binder-free Ti-MWW zeolite with enhanced diffusion efficiency. Successive piperidine treatment and fluoridation further enhanced the activation ability of active Ti sites, resulting in a more efficient epoxidation process. Additionally, the modification effectively inhibited the side reaction of PO hydrolysis by quenching numerous Si-OH groups, leading to a high catalyst lifetime with excellent H2O2 conversion and PO selectivity.

Summary: In this study, a dual-core layer hollow structure Co3S4@NiCo2S4 nanocages supercapacitor electrode material was successfully synthesized using an appropriate ion-exchange strategy and subsequent vulcanization treatment of MOFs. The Co3S4@NiCo2S4 electrode exhibited a specific capacitance of 1202 F g-1 at 1 A g-1 and retained 80% of its initial capacity at 10 A g-1. The integrated Co3S4@NiCo2S4//AC asymmetric supercapacitor achieved an energy density of 58 Wh kg-1 at a power density of 750 W kg-1. It also showed a capacitance retention of 81.8% after 10,000 galvanostatic charge-discharge cycles. The individual nanostructure and excellent electrochemical properties of Co3S4@NiCo2S4 nanocages provide a rational strategy for developing high-energy-density supercapacitor electrode materials based on MOFs derivatives.

Summary: An environmentally friendly Ce@W core-shell catalyst was developed for the selective catalytic reduction of NOx. It has higher tolerance to SO2 and H2O and displays 100% conversion of NOx and selectivity to N2 in the temperature range of 250-450°C. The enhanced performance is attributed to the strong interactions between CeO2 (100) and WO3, which increase the presence of Ce3+ and surface chemisorbed oxygen.

Summary: The phosphorus chemical shift anisotropies, P-31 Delta cs, and asymmetry parameters eta were measured in zirconium phosphates, phosphonates, and mixed Zr (IV)/Sn (IV) phosphate/phosphonate material using P-31{H-1} NMR experiments. The experiments showed a 111 connectivity in the HPO4 and PO3 groups, which remained the same after modification and intercalation of the materials. The phosphonate groups had higher P-31 Delta cs values compared to the HPO4 groups. The P-31 chemical shift anisotropy parameters are important for elucidating local structures in phosphate and phosphonate materials.

Summary: A linker design strategy is developed to create novel polynuclear rare-earth metal-organic frameworks (MOFs) with unprecedented topologies. The study reveals the crucial role of ortho-functionalized tricarboxylate ligands in directing the construction of highly connected RE MOFs. Different functional groups at the ortho position of the carboxyl groups alter the acidity and conformation of the tricarboxylate linkers, resulting in the formation of various RE MOFs with unique topologies. This work expands the library of polynuclear clusters in RE MOFs and opens up new possibilities for constructing MOFs with complex structures and wide-ranging applications.

Summary: The study of a layered crystalline Sn(IV) phosphate using solid-state NMR revealed that the 31P T1 relaxation of phosphate groups, which depends on spinning rate, is controlled by limited spin diffusion to paramagnetic ions identified by EPR. The spin-diffusion constant, D(SD), was estimated to be 2.04 10-14 cm2s 1. This conclusion was further supported by 31P T1 time measurements in zirconium phosphate 1-1, which also contain paramagnetic ions, and in the diamagnetic compound (NH4)2HPO4.
