2024年9月18日 · In this work, ZIF-67 derived Co 2 (P 4 O 12) and CoSe 2 heterostructures (Co 2 (P 4 O 12)/CoSe 2 /CNFs) loaded on carbon nanofibers have been constructed using a combination of an in situ growth method and electrostatic spinning technique.

2020年7月24日 · Herein, we report two new cyclotetraphosphates containing no rare earth element, cubic CsBi (P 4 O 12) and its isostructural RbBi (P 4 O 12). Single crystal diffraction data reveal their I4 3 d structures featuring the isolated cyclic …

2018年4月2日 · 五氧化二磷 只是系数约分后的最简式，也是以前的习惯写法。 无论磷的哪种同素异形体形成的最高价氧化物都是 十氧化四磷。 至于P2O5和P4O10写哪种都是可以的（建议写后一种）。 （为什么？

Herein, we report two new cyclotetraphosphates containing no rare earth element, cubic CsBi (P4O12) and its isostructural RbBi (P4O12). Single crystal diffraction data reveal their I43d structures featuring the isolated cyclic [P4O12] building blocks with multiple orientations.

A single-crystal X-ray diffraction analysis has been performed on LiNdP4O12synthesized by the flux method. The crystal belongs to monoclinic system, with space group C2/c, z=4, and cell parameters α= 16.486?, b = 7.073 ?, c =9.775? and β = 126.23°. A full-matrix, least square refinement gave R = 0.054, Rω= 0.050 for 1251 independent reflections.

2024年5月28日 · Transition metal tetrametaphosphates (M 2 P 4 O 12) are a novel electrode material for lithium-ion batteries (LIBs) due to their good electrical conductivity and reversible redox behavior. In this work, carbon layer self-encapsulated Ni 2 P 4 O 12 nanoparticles were prepared by facile oil bath evaporation and high temperature calcination.
