摘要:
This invention relates to method for improving selectivity in liquid phase chemical reactions by flowing a reaction solution through a solution reaction column packed with particles having a multiplicity of nanometer-order pores, wherein the chemical reaction solution containing molecules to be reacted is flowed through mesopores having diameter on the order of several nanometers and length on the order of several ten nanometers, while simultaneously subjected to activating of the reaction thereof with reaction-initiating/accelerating means during the process; and a solution flow reaction system therefor.
摘要:
To provide a novel visible light-responsive photocatalyst or tungsten oxide visible light-responsive semiconductor improved in environmental resistance under an alkaline condition.The tungsten oxide visible light-responsive semiconductor unstable under an alkaline condition is improved in environmental resistance without losing photocatalytic function thereof by adding thereto at least one element selected from the group consisting of copper, tantalum, niobium, lanthanum, bismuth, calcium, chromium, manganese and zinc. The obtained environmental resistant visible light-responsive photocatalyst is subjected to an alkaline treatment to thereby be improved in photocatalytic activity.
