“…This chapter deals with the synthesis of WO 3 and MoO 3 nanoplates using H 2 WO 4 , H 2 W 2 O 7 , and MoO 3 ·H 2 O solid powders as the starting materials. [1][2][3][4][5][6][7] The synthesis of carbides and nitrides of tungsten is also introduced using the as-obtained tungstate-based inorganic-organic hybrid compounds as precursors. [8,9] The applications of WO 3 and MoO 3 nanoplates in sensors are also introduced.…”
