采用有机结构导向剂（SDA）的软模板法制备多孔金属氧化物，主要问题是结晶所需温度较高，有机SDA模板金属氧化物的液晶在金属氧化物的无定形壁开始结晶之前就会分解。通常，这些材料不是完全结晶的，而是由纳米颗粒稳定地结合在非晶基体中，由于处理温度低（400- 450 ℃）而形成半结晶结构。
For the soft template method to fabricate poroustransition metal oxides in which organic structure-directingagents (SDA) are involved, the main problem is that thetemperature required for the crystallization is normally highand the liquid crystals of organic SDA templating the metaloxide would decompose before the amorphous walls of metaloxides start to crystallize. Often such materials were not fullycrystallinebutinsteadcomposedofnanocrystalsembeddedinamorphous matrix to form a semicrystalline structure owingto the low treatment temperature (400–4508C).
