α-MoO3 crystals with a multilayer stack structure obtained by annealing from a lamellar MoS2/g-C3N4 nanohybrid Martín Ramos, Pablo Alonso Fernández-Coppel, Ignacio Avella, Manuel Martín Gil, Jesús Transition metal oxides and chalcogenides have recently attracted great attention as the next generation of 2-D materials due to their unique electronic and optical properties. In this study, a new procedure for the obtaining of highly crystalline α-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) α-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. 2022-10-14T11:32:21Z 2022-10-14T11:32:21Z 2022-10-14T11:32:21Z 2018 info:eu-repo/semantics/article Nanomaterials, 2018, vol. 8, n.7, p. 559 2079-4991 https://uvadoc.uva.es/handle/10324/55961 10.3390/nano8070559 559 7 Nanomaterials 8 2079-4991 eng https://www.mdpi.com/2079-4991/8/7/559 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2018 The Author(s) Atribución 4.0 Internacional MDPI
