A series of Pd/MIL-53(Al) heterogeneous bifunctional catalysts with di erent Pd contents were prepared by an impregnation method. The prepared metal–organic frameworks MIL-53(Al) and catalysts were characterized by XRD, SEM, hRTEM,FT-IR and N2 adsorption/desorption techniques. The results showed that MIL-53(Al) was synthesized successfully, and the structure was unchanged during and after the preparation of the catalysts. The Pd nanoparticles(NPs) with an average particle size of 4.6 nm were uniformly dispersed on the MIL-53(Al). The catalyst exhibited good catalytic activity in the selective oxidation of liquid methanol to methyl formate. Under the conditions of 150 °C, 2 MPa O2 and solvent-free for5 h, the conversion of methanol could reach 60.3%, and the selectivity of methyl formate was up to 62.2%. In addition, the Pd/MIL-53(Al) bifunctional catalyst exhibited excellent stability and maintained high catalytic activity after five cycles.

In this work, nickel metal supported on different supports(SiO_2, Al_2O_3, ZSM-5) were prepared by spraying nickel nitrate on the supports and calcined at 873 K. Then, they were characterized by XRD, XRF, N_2 adsorption–desorption, Nh_3-TPD, MCh-TPD, h_2-TPR, and pyridine-FTIR,and tested as catalysts for the dehydrogenation aromatization and isomerization of methylcyclohexane(MCh) under the conditions of S-Zorb catalytic adsorption desulfurization(T ? 673 K, P ? 1.5 MPa, WhSV ? 5 h^(-1)). The h2-TPR results showed that the interaction of NiO with support decreased in the order of NiO/ZSM-5-Fe he decrease of the interaction appeared to facilitate the reduction of Ni and therefore to promote the dehydrogenation aromatization of *** was found that a direct correlation existed between the gasoline components yields, cracking activity and the total number of different supports acid sites measured by Nh_3-TPD tests. higher total acidity of ZSM-5 resulted in gasoline loss because of higher cracking activity of MCh. The number of total acid sites of NiO/ZSM-5-Fe decreased and the medium strong Br€onsted acid sites necessary for MCh isomerization increased after the modification of ZSM-5 by iron metal. So, NiO/ZSM-5-Fe exhibited enhanced MCh conversion, aromatic and isomerization yields when compared to NiO/ZSM-5 and other Ni-based catalysts. This study shows that NiO/ZSM-5-Fe catalyst may be possible to be integrated into the S-Zorb system achieving the recovery of the octane number of gasoline.

Three new complexes have been prepared based on the transition metals and zwitterionic dicarboxylate ligand 1,1＇-（1,4-phenylene-bis（methylene））-bis（pyridine-3-carboxylic acid）（L）, whose formulas are {[Cd4（L）（SO4）]· （C1）6}n （1）, [Zn（L）C12], （2）, and [Co（L）C12], （3）, respectively. Complexes 1-3 have been characterized by elemental analyses, IR spectroscopy, XRD, thermal analyses and single crystal X-ray （powder） diffraction. 1 crystallizes in monoclinic space group C2/m, displaying a 2-D layer structure with three unique Cd^2＋ centers. 2 and 3 are iso- morphic structures with the orthorhombic Cmca space group. They exhibit a 1-D zigzag chain, which can be linked to generate a 2-D layer via hydrogen bonding interactions （C--h＇＂O）. Moreover, electrochemical behavior reveals that the redox reaction of 3-CPE is a surface-controlled reaction. And the luminescent properties of the title comlexes have been investigated at room temperature.

Peripheral nerve injuries induce a severe motor and sensory deficit. Since the availability of autologous nerve transplants for nerve repair is very limited, alternative treatment strategies are sought, including the use of tubular nerve guidance conduits(tNGCs). however, the use of tNGCs results in poor functional recovery and central necrosis of the regenerating tissue, which limits their application to short nerve lesion defects(typically shorter than 3 cm). Given the importance of vascularization in nerve regeneration, we hypothesized that enabling the growth of blood vessels from the surrounding tissue into the regenerating nerve within the tNGC would help eliminate necrotic processes and lead to improved regeneration. In this study, we reported the application of macroscopic holes into the tubular walls of silk-based tNGCs and compared the various features of these improved silk^(+) tNGCs with the tubes without holes(silk^(–) tNGCs) and autologous nerve transplants in an 8-mm sciatic nerve defect in rats. Using a combination of micro-computed tomography and histological analyses, we were able to prove that the use of silk^(+) tNGCs induced the growth of blood vessels from the adjacent tissue to the intraluminal neovascular formation. A significantly higher number of blood vessels in the silk^(+) group was found compared with autologous nerve transplants and silk^(–), accompanied by improved axon regeneration at the distal coaptation point compared with the silk^(–) tNGCs at 7 weeks postoperatively. In the 15-mm(critical size) sciatic nerve defect model, we again observed a distinct ingrowth of blood vessels through the tubular walls of silk^(+) tNGCs, but without improved functional recovery at 12 weeks postoperatively. Our data proves that macroporous tNGCs increase the vascular supply of regenerating nerves and facilitate improved axonal regeneration in a short-defect model but not in a critical-size defect model. This study suggests that further optimizatio
