“…In addition, the reducing trend of lanthanide ionic radius with increasing atomic number will cause the smallest radius Tb III ion being more close to the crown plane. Thus, among the reported six metallacrowns, Tb III complex 3 present higher rigidity and bigger steric hindrance, 22 and it is disadvantage for the intercalation between complex and DNA.…”

“…These facts imply that varying coordination environment and site geometries can mediate the catalytic performance of desired OER catalysts. As a member of the Co-Pi materials family, Co 2 P 2 O 7 possesses unique optical, electrical, magnetic, and catalytic properties, showing great potential to use in coatings, Li-ion batteries, supercapacitors, magnetism and microwave absorption, as well as heterogeneous catalysis fields. − By far, some Co 2 P 2 O 7 nanostructures, such as nanoparticles, nanorods, and hierarchical 3D nano/microarchitectures, , have been fabricated via different synthetic strategies. To the best of our knowledge, there is still no report on coralloid Co 2 P 2 O 7 nanocrystals or their derived nanohybrids, albeit great progress has been made in biomimetic nanostructures, and their OER activities are unknown until now.…”

Core-shell nanohybrids containing cheap inorganic nanocrystals and nanocarbon shells are promising electrocatalysts for water splitting or other renewable energy options. Despite that great progress has been achieved, biomimetic synthesis of metal phosphates@nanocarbon core-shell nanohybrids remains a challenge, and their use for electrocatalytic oxygen evolution reaction (OER) has not been explored. In this paper, novel nanohybrids composed of coralloid Co2P2O7 nanocrystal cores and thin porous nanocarbon shells are synthesized by combination of the structural merits of supramolecular polymer gels and a controllable thermal conversion technique, i.e., temperature programmable annealing of presynthesized supramolecular polymer gels that contain cobalt salt and phytic acid under a proper gas atmosphere. Electrocatalytic tests in alkaline solution show that such nanohybrids exhibit greatly enhanced electrocatalytic OER performance compared with that of Co2P2O7 nanostructure. At a current density of 10 mA cm(-2), their overpotential is 0.397 V, which is much lower than that of Co2P2O7 nanostructures, amorphous Co-Pi nanomaterials, Co(PO3)2 nanosheets, Pt/C, and some reported OER catalysts, and close to that of commercial IrO2. Most importantly, both of their current density at the overpotential over 0.40 V and durability are superior to those of IrO2 catalyst. As revealed by a series of spectroscopic and electrochemical analyses, their enhanced electrocatalytic performance results from the presence of thin porous nanocarbon shells, which not only improve interfacial electron penetration or transfer dynamics but also vary the coordination environment and increase the number of active 5-coordinated Co(2+) sites in Co2P2O7 cores.

“…It is verified that the main products in the char residue of CoPP, NiPP, CuPP, and FePP, can be assigned to Co 2 P 2 O 7 , Ni 2 P 2 O 7 , Cu 2 P 2 O 7 , and Fe 2 P 2 O 7 , respectively. Six diffraction peaks shown in Figure a can be attributed to (1̅02), (021), (012), (220), (032) and (4̅24) planes of Co 2 P 2 O 7 (JCPDS-49-1091) . Four peaks exhibited in Figure b can be assigned to (210), (002), (212), (230), and (5̅13) planes of Ni 2 P 2 O 7 (JCPDS-74-1604) .…”

In this work, layered metal phenylphosphonates are synthesized via hydrothermal method and their morphology is observed by scanning electron microscopy and transmission electron microscopy. Then, their polystyrene (PS) composites with 2 wt % phenylphosphonates are fabricated and thermal stability as well as combustion behavior are investigated. Excellent dispersion state of fillers and strong interfacial interaction between PS and phenylphosphonates are achieved. Char residue yield of the PS composites is enhanced in TGA test and the values of peak heat release rate are decreased appreciably, suggesting the improvements in thermal stability and flame retardancy. Moreover, the amount of aromatic compounds released from PS is decreased remarkably after the incorporation of phenylphosphonates.
