| Abstract: | An approach named “pore structure collapsed replication route” has been developed to prepare mesoporous WC materials with
a high surface area (105 m2/g) and crystallized framework at a temperature as low as 700 °C. The XRD, TEM, EDS, and BET characterizations were conducted
to analyze the effects of the synthesis parameters and the template types on the structure of mesoporous WC. The compaction
on the templates is the key to form mesoporous structure of WC while the templates help to control the size of crystalline.
At a content of 7 wt% for the precursor of WC, the mesoporous WC could be formed with well ordered structure. |
