Heat-treatment of metal–organic frameworks for green energy applications

Facile synthesis of novel metal-organic nickel hydroxide nanorods for high performance supercapacitor

“…186.8 m 2 g -1 calculated from the desorption line, which is higher than most reported MOF nanomatrials [8,12,15,28,29]. The high surface area helps to improve the contact area between electro active materials and electrolyte ions, and thus the specific capacitance can be substantially increased.…”

“…According to the role of nano-sized MOFs in supercapacitors, their application range can be divided into two categories. In one case, MOFs acted as tuneable porous templates to synthesize mesoporous carbon [5], metal oxide [6], and metal sulphide [7] via a pyrolysis reaction under inert atmosphere for supercapacitors [8]. In the other case, pristine MOFs serve as direct electro active materials for supercapacitors and their capacitances are based on the reversible redox reactions of the metal 6 centres [9,10].…”

“…In this paper, 1D Ni-based MOF nanorods with uniform morphology were successfully synthesized under mild conditions using salicylic acid as new organic linker and used as supercapacitor electrodes for the first time. 8 Ni-based MOF nanorods were prepared by a complexation reaction of Ni 2+ and HOC 6 H 4 COO -followed by a hydrothermal process. Firstly, an aqueous 28 mL Ni(NO 3 ) 2 solution (0.02 mol L -1 ) was slowly added to 42 mL o-HOC 6 H 4 COONa solution (0.02 mol L -1 ) drop by drop under continuous stirring at room temperature.…”

A Rational Strategy To Construct a Neutral Boron Imidazolate Framework with Encapsulated Small-Size Au–Pd Nanoparticles for Catalysis

“…The tetradentate B(im) 4 − and oxalate ligands linked the six-coordinated and 5-connected Cd 2+ centers into a 3D framework with tcs topology (Figure 1d). Therein, B(im) 4 − ligands connect Cd 2+ ions into a (4,4)-connected layer ( Figure 1a). Also, the oxalate ligands further bridge the adjacent layers to form the 3D framework structure of BIF-39-Cd ( Figure 1c).…”

“…The thermogravimetric behavior and phase purity of BIF-39-Cd have been demonstrated by thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD), respectively (Figures S1 and S2 in the Supporting Information, SI). In the structure of BIF-39-Cd, each Cd 2+ center is coordinated by four N atoms from four B(im) 4 − ligands and two O atoms from an oxalate ligand, exhibiting an octahedral coordination geometry. The tetradentate B(im) 4 − and oxalate ligands linked the six-coordinated and 5-connected Cd 2+ centers into a 3D framework with tcs topology (Figure 1d).…”
