photochemical catalyst meaning in Chinese

光催化剂
光化学触媒

Using v2 & 5 and alkylamines ( cs - cao alkyl chain ) as precursor , vanadium oxide nanotubes which have an unique structure that alkylamines intercalate into layers of tubes wall affecting the layer spacing were prepared . their layers spacing ranges from 1 . 25 nm to 3 . 82 nm according to the length of alkyl chain . moreover , the growth mechanism of vanadium oxide nanotubes have been investigated and 3 - 2 - id model was established to interpret the vanadium oxide nanotubes growth process . potassium niobate is a functional materials which can be used as photochemical catalysts . lt is well known that the catalytic activites are affected greatly by the surface area of catalyst particles on which the reaction take place
以系列烷基胺和五氧化二钒为原材料，通过简单的水热反应合成出了氧化钒纳米管，这种纳米管结构独特，烷基胺作为模板剂内嵌入纳米管管壁层间，成为支持纳米管的骨架，并影响层间距大小，纳米管管壁层间距随着烷基胺碳链长度的不同在很大范围内变化，通过采用不同碳链长度的烷基胺( c _ nh _ ( 2n + 1 ) nh _ 23 n 20 )作为模板，来控制氧化钒纳米管的层间距，层间距可调控范围从1 . 25nm到3 . 82nm 。
