Effect of water intercalation on VO_x layers in dodecylamine-intercalated vanadium oxide nanotubes

摘要

Dodecylamine-intercalated vanadium oxide nanotubes were obtained by distinct synthesis processes. Water intercalation in the nanotube structure was identified in a marked manner by the distortion of the VO_x layers in the x-ray diffraction patterns and enhanced V~(4+)=O absorption in the Fourier-transform infrared spectra. Our electron spin resonance measurements sensitively reflect changes in the microscopic structure and magnetic interactions introduced by the water intercalation in the vanadium oxide nanotubes.
