“…The introduction of a secondary pore system in order to create a hierarchical porous structure has been proven as an advantageous strategy in zeolite catalysis [163]. Recently, this approach was developed for modifying nanoporous MOF matrices [164][165][166][167][168]. This way of the rational design of MOF porous structures extends essentially application fields in catalysis by MOF materials.…”

: Currently, metal–organic frame works (MOFs) as novel hybrid nanoporous materials are a top research interest, including endeavors in heterogeneous catalysis. MOF materials are promising heterogeneous catalytic systems due to their unique characteristics, such as a highly ordered structure, a record high surface area and a compositional diversity, which can be precisely tailored. Very recently, these metal-organic matrices have been proven as promising catalysts for biomass conversion into value-added products. The relevant publications show that the structure of MOFs can contribute essentially to the advanced catalytic performance in processes of biomass refining. This review aims at the consideration of the different ways for the rational design of MOF catalysts for biomass processing. The particular characteristics and peculiarities of the behavior of different MOF based catalytic systems including hybrid nanomaterials and composites will be also discussed by illustrating their outstanding performance with appropriate examples relevant to biomass catalytic processing.

“…2d-f, these Cu-BTC_An samples also exhibit similar shapes and pore structures, with dense, uniform nanoakes randomly stacked together and abundant voids in between. Cao et al 49 and Hirai et al 50 also reported that hierarchical porous structures in MOFs are formed through the aggregation or packing of microporous nanoparticles. Although void structures are clearly observed in all of the Cu-BTC_An samples (Fig.…”

Hierarchical porous metal-organic frameworks (HP-MOFs) with tunable porosity are highly valuable for many applications. Here, we developed a versatile solvothermal method to synthesize various HP-MOFs, such as Cu-BTC and ZIF-8, by using an organic amine as the template. The resulting HP-MOF products were characterized by a complementary combination of X-ray powder diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, nitrogen adsorption-desorption isotherms, pore size distributions analysis, thermogravimetric analysis, and density functional theory calculations. The results indicated that the obtained HP-MOF products had high thermal stability and contained multimodal hierarchically porous structures with mesopores or macropores interconnected with micropores. In addition, the porosities of the produced HP-MOFs could be easily tuned by controlling the amount of the template. The introduced organic amine served as the template to direct the formation of mesopores and macropores. Furthermore, the synthesis route is highly versatile as other organic amines (e.g., N,N-dimethylhexadecylamine and N,Ndimethyltetradecylamine) can also be used as templates to synthesize HP-MOFs. The method developed in this work may offer a new direction to synthesize various stable HP-MOFs with tunable porosities for a wide range of applications.

“…Mn(II), have received increasing attention, owing to its high spin ground state can be obtained from strong exchange interactions between 3d electrons [1][2][3][4][5][6][7][8][9][10]. Noted that, the development of coordination chemistry, many research efforts have been devoted to novel ways to fabricate, characterize and explore fundamental magnetic phenomena [11][12][13][14][15][16][17][18][19][20][21][22][23]. Coordination polymers (CPs) with polynuclear units based on Co(II) and Mn(II) have fascinating architectures and physical properties with widespread applications, such as catalysis, sorption, magnetism and electrical conductivity [24][25][26][27][28][29][30].…”

Two new Co(II) coordination polymers(CPs), namely [Co 2 (bpe) 2 (Hbppc)] n (1) and [Co 3 (μ 3-OH)(bppc)(bpm)(H 2 O)]•3H 2 O (2) (H 5 bppc = biphenyl-2,4,6,3',5'-pentacarboxylic acid, bpe = 1,2-bis(4-pyridyl)ethene, bpm = bis(4-pyridyl)amine), have been obtained and characterized by elemental analysis, single-crystal X-ray diffraction, powder X-ray diffraction (PXRD), IR spectra and thermogravimetric analysis (TGA). 1 shows a binodal (4,6)-connected fsc net with a (4 4 •6 10 •8)(4 4 •6 2) topology, while 2 shows a binodal (5,7)-connected 3D network based on trinuclear [Co 3 (μ 3-OH)] 5+ units with unusual (3.4 6 .5 2 .6)(3 2 .4 6 .5 7 .6 5 .7) topology. Variable-temperature magnetic susceptibility measurements reveals that complex 1 shows ferromagnetic interactions between the adjacent Co(II) ions, whereas 2 is a antiferromagnetic system.
