In this study, a new procedure for the obtaining of highly crystalline a-MoO3 is proposed as an alternative to vapor-phase synthesis. In this approach, a first reaction between molybdate, citrate and thiourea allowed to obtain MoS2, which—upon calcination at a temperature of 650 °C in the presence of g-C3N4—resulted in MoO3 with a definite plate-like shape. The colorless (or greenish) a-MoO3 nanoplates obtained with this procedure featured a multilayer stack structure, with a side-length of 1–2 µm and a thickness of several nanometers viewed along the [010] direction. The nucleation-growth of the crystal can be explained by a two-dimensional layer-by-layer mechanism favored by g-C3N4 lamellar template. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.034 2018 MATERIALS SCIENCE, MULTIDISCIPLINARY 71 / 293 = 0.242 2018 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 39 / 94 = 0.415 2018 Q2 T2 0.896 2018 Materials Science (miscellaneous) 2018 Q1 Chemical Engineering (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Fernández-Coppel, Ignacio A.
