Pyrochlore　W2O6·H2O　were　successfully　prepared　via　a　facile　and　rapid　hydrothermal　process　in　the　presence　of　fluorinion.　It　is　worth　noting　that　our　developed　method　can　efficiently　overcome　the　tedious　process　in　the　preparation　of　nanostructured　tungstic　oxide　in　the　previous　reports.　The　as-prepared　samples　have　been　characterized　by　XRD,　SEM　and　TEM.　Results　showed　the　morphologies　of　the　samples　were　nanoplate　and　the　thickness　of　the　plate　was　estimated　at　about　several　nanometers.　TEM　image　further　revealed　that　the　plates　were　trigonal-like　with　equal　lengths　of　about　300　nm.　Furthermore　the　selected　area　electron　diffraction　(SAED)　pattern　taken　from　a　single　nanoplate　indicated　that　the　nanoplates　were　the　single　crystals　with　a　preferential　growth　direction　along　the　[011]　direction.　The　effect　of　the　additive　ions　on　the　formation　has　also　been　discussed.　It　was　found　that　the　fluorinion　played　a　key　role　in　the　formation　of　W2O6·H2O　nanoplates.　It　is　hoped　that　our　work　could　provide　a　new　insight　into　the　facile　and　rapid　preparation　of　metal　oxide　nanomaterials.　Copyright　©　2014　American　Scientific　Publishers.
