Crystalline nanobelts of α-MoO 3 have been obtained successfully using novel and safe agents through a simple and safe sol–gel method (polymerizing–complexing) and characterized by XRD, FT-IR, Raman spectroscopies, high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and the temperature programmed desorption (TPD) of ammonia. An orthorhombic lattice system for nano-MoO ...
