C03O4-2 could be obtained with Ig KIT-6 template) in laboratory, and long time stirring/refluxing is not needed. Even for the large amount samples preparation, similarly a multi-drop wise wetting technique (e.g., by solution spraying) can also be adapted. 

Zhao[266] demonstrated the successful synthesis of highly ordered mesoporous silicon carbides with unusually high surface areas (430-720 m2/g), uniform pore sizes (<3.5 nm), and extremely high thermal stabilities (up to 1400 °C) replicated by mesoporous silica hard templates via a one-step nanocasting process. Highly ordered 2-D hexagonal (p6m) and bicontinuous cubic (Ia3d) SiC nanowire arrays have been cast from the hard templates, mesoporous silica SBA-15 and KIT-6, respectively. 

Mesoporous crystalline M0O3 and WO3 were obtained in thin films. Ordered mesoporous WO3 was first produced using the soft template method. By changing formation conditions, cubic and hexagonal mesoporous structures were obtained. The hard template method using SBA-15 or KIT-6 produced ordered mesoporous crystalline WO3 materials. With SBA-15 as a template, a porous single crystal was formed, while polycrystalline porous WO3 materials were formed with a KrT-6 template,although reaction conditions were similar. 

Recently, synthesis of ordered mesoporous crystalline P-Mn02 using KIT-6 as a hard template has been reported. " Because of the large surface area and accessibility to the crystalline wall with the ordered mesoporous structure, mesoporous P-Mn02 facilitates fast transport of... 

Ordered mesoporous C03O4 was prepared by using hard templates such as SBA-15, FDU-12, KIT-6 and Both mesopor-... 

Figure 3.4 (a) Wide-angle powder XRD patterns of mesoporous perovskite oxides synthesized using ordered mesoporous KIT-6 aged at 100°C as the hard template. The lowest curve corresponds to the LaMnOs perovskite synthesized without using citric acid.

KIT-6 silica template was removed from the resulting solids by leaching twice with 2 M NaOH (Merck) at 50°C, while mixing the suspension on the magnetic stirrer.
