“…The structure was elucidated using PXRD data and revealed that not only Epy but also pyridinium (py) was occluded between the layers, and the results were also in close agreement with elemental analysis data. 89 Compared to other templates, yeast cells are nontoxic, biodegradable, and pollution-free, which is consistent with the principles of green chemistry. 91 In one such attempt, Tian et al demonstrated the synthesis of mesoporous zirconium phosphate using yeast biotemplate under ambient conditions and fabricated an air electrode that exhibits remarkable electrocatalytic activity for the oxygen reduction reaction (ORR).…”

As a fascinating two-dimensional (2D) layered inorganic ion exchange material, zirconium phosphate (hereafter ZrP) has drawn interdisciplinary attention as an ion exchange material and a competent host for surface functionalization and intercalation. This is due to its captivating properties such as simple synthesis procedure, excellent ion-exchange capacity, excellent chemical, thermal, and radiolytic stability, tunable interlayer gallery, and good biocompatibility. Among all the well-known phases of ZrP, we restrict our discussion only to the alpha (α-ZrP) and gamma (γ-ZrP) phases for their efficient ion exchange performance and more tunable interlayer spacing. This review summarizes a panorama of the recent research progress on the synthesis, intercalation, and surface functionalization of ZrP with organic molecules, metal complexes, and metal ions for the design and fabrication of self-assembled monolayers, layer-by-layer assemblies, and nanocomposites. Within the confined gallery microenvironment of ZrP, usual molecules behave unusually with dramatic enhancement in the photophysical properties. The intercalation of metal complexes and their fascinating electronic properties will also be comprehensively highlighted in this review. Furthermore, for the first time, a cutting-edge advancement (2010 onward) of the versatile adsorption performance of ZrP-based materials for the uptake of toxic metal ions which include nuclear waste-related metal ions, heavy metal ions, and rare earth ions will be presented in detail. Last but not least, the review will conclude with the summary and future directions, which will provide new research opportunities for the development of ZrP based sustainable heterofunctional material.

“…32−34 Although our main focus here is on the structure analysis of zeolites, the method is quite general for locating organic guest species in inorganic host materials. We have applied it to locate the organic species between the zirconium phosphate layers of ZrPOF-EPY, 35 the ligand in a Mo oxide/pyrazolylpyridine polymeric hybrid material, 36 and the ligand of a Cu coordination complex that was part of a multiphase product obtained by decomposing the metal−organic framework of HKUST-1. 37 In the case of ZIF-L, 38 we were only able to locate the Zn anions initially, and used simulated annealing to simplify the problem of locating the organic linker.…”

Can the location of the organic structure-directing agent (SDA) inside the channel system of a zeolite be determined experimentally in a systematic manner? In an attempt to answer this question, we investigated six borosilicate zeolites of known framework structure (SSZ-53, SSZ-55, SSZ-56, SSZ-58, SSZ-59, and SSZ-60), where the location of the SDA had only been simulated using molecular modeling techniques in previous studies. From synchrotron powder diffraction data, we were able to retrieve reliable experimental positions for the SDA by using a combination of simulated annealing (global optimization) and Rietveld refinement. In this way, problems arising from data quality and only partially compatible framework and SDA symmetries, which can lead to indecipherable electron density maps, can be overcome. Rietveld refinement using geometric restraints were then performed to optimize the positions and conformations of the SDAs. With these improved models, it was possible to go on to determine the location of the B atoms in the framework structure. That is, two pieces of information that are key to the understanding of zeolite synthesis-the location of the organic SDA in the channel system and of the positions adopted by heteroatoms in the silicate framework-can be extracted from experimental data using a systematic strategy. In most cases, the locations of the SDAs determined experimentally compare well with those simulated with molecular modeling, but there are also some clear differences, and the reason for these differences can be understood. The approach is generally applicable, and has also been used to locate organic guests, linkers, and ligands in metal-organic compounds.

“…Although there have been some reports on the synthesis of nanoporous crystalline phosphates in the presence of smaller organic molecules (such as 1,2-diaminocyclohexane and diethylenetriamine) as a template or in the absence of templates, the obtained materials are micrometer-sized crystals, , which are a thousand times larger than architectural pores (typically <1 nm in diameter). Due to this structural obstruction, the materials often suffer from diffusion limitations that restrict their application in energy storage and the transfer process. , Therefore, there has been limited success in finding a relatively simple way to synthesize nanoporous metal phosphates with high surface areas and controlled morphologies and crystallinity. − …”

Nanoporous nickel, aluminum, and zirconium phosphates (hereafter, abbreviated as NiP, AlP, and ZrP, respectively) with high surface areas and controlled morphology and crystallinity have been synthesized through simple calcination of the corresponding phosphonates. For the preparation of phosphonate materials, nitrilotris(methylene)triphosphonic acid (NMPA) is used as phosphorus source. The organic component in the phosphonate materials is thermally removed to form nanoporous structures in the final phosphate materials. The formation mechanism of nanoporous structures, as well as the effect of applied calcination temperatures on the morphology and crystallinity of the final phosphate materials, is carefully discussed. Especially, nanoporous NiP materials have a spherical morphology with a high surface area and can have great applicability as an electrode material for supercapacitors. It has been found that there is a critical effect of particle sizes, surface areas, and the crystallinities of NiP materials toward electrochemical behavior. Our nanoporous NiP material has superior specific capacitance, as compared to various phosphate nanomaterials reported previously. Excellent retention capacity of 97% is realized even after 1000 cycles, which can be ascribed to its high structural stability.
