Photocatalysis with suspended photocatalyst is more efficient than that with supported photocatalyst 摘要悬浮态的光催化反应器相比固载的光催化反应器有更高的光催化效率。
The film prepared at low temperature was amorphous tio2 and it ' s photocatalysed efficiency was very low Apcvd法在较低的基板温度下制备出的tio _ 2薄膜基本上是非晶态的,光催化效率很低。
On the basis of uv - vis transmissive spectra , the sputtered films have absorption peaks toward longer wavelength , and the calculation shows the lower optical band gap 适当的掺杂量可以产生新的吸收峰,增加对长波段光的吸收,提高光催化效率。
It was found that loop reactor could narrow the molecular weight distribution , increase the content of carbonate in product molecules and improve catalyst efficiency 研究发现,环流反应器能够使产品分子量分布变窄,提高产品中碳酸酯基团含量及催化剂的催化效率。
New methods for asymmetric synthesis of pinacol are reviewed , the catalytic effects and stereo - selectivity with various catalytic systems are discussed in this paper 摘要综述了近年来不同催化体系的不对称合成(口片)呐醇的方法,并总结了不同的催化效率和对映选择性的差异。
