A phosphorus allotrope that has not been observed so far, ring-shaped phosphorus consisting of alternate P and P structural units, has been assembled inside multi-walled carbon nanotube nanoreactors with inner diameters of 5-8 nm by a chemical vapor transport and reaction of red phosphorus at 500 °C. The ring-shaped nanostructures with surrounding graphene walls are stable under ambient conditions. The nanostructures were characterized by high-resolution transmission electron microscopy, scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy, Raman scattering, attenuated total reflectance Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy.
一种迄今为止尚未被观察到的磷同素异形体，即由交替的 P 和 P 结构单元组成的环形磷，已经通过在 500°C 时对红磷进行化学气相输运和反应，在 5-8nm 内径的多壁碳纳米管纳米反应器中组装而成。具有环绕石墨烯壁的环形纳米结构在环境条件下是稳定的。这些纳米结构通过高分辨率透射电子显微镜、扫描透射电子显微镜、能量色散 X 射线能谱、拉曼散射、衰减全反射傅里叶变换红外光谱和 X 射线光电子能谱进行了表征。
