<P>PROBLEM TO BE SOLVED: To provide a production method of a vanadium pentoxide gel, by which intrusion of impurities in a final product is prevented during the production, the production can be safely carried out without any injuries, and excellent production efficiency is obtained. <P>SOLUTION: A vanadium pentoxide gel is synthesized by a photochemical reaction using a photochemical effect of vanadium pentoxide (a chemical reaction by an electron-hole pair produced by absorption of light), through a step of irradiating a suspension prepared by dispersing a vanadium pentoxide crystal in water, with light having a wavelength component of 560 nm or shorter, whose wavelength is shorter than an absorption edge at which vanadium pentoxide absorbs light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
