WebLayered anode materials based on aqueous electrolytes have been studied in a three-electrode system. MTi 2 NbO 7 (M = H、Li、Na、K) was prepared by different ion exchange of precursors CsTi 2 NbO 7, and the crystal structures and skeleton structures of the as-prepared materials were characterized by X-ray diffraction (XRD) and laser Raman … WebTFBDC) is a common building block for the construction of perfluorinated coordination polymers and MOFs, 29. thanks to its commercial availability. The structural analogies between H. 2. TFBDC and terepththalic acid (H. 2. BDC) could lead to assume that the preparation of perfluorinated isoreticular versions of the most common MOF topologies ...
