WebSep 23, 2024 · Liquid-phase adsorption has hardly been established in micro-flow, although this constitutes an industrially vital method for product separation. A micro-flow UV-photo isomerization process converts cis-cyclooctene partly into trans-cyclooctene, leaving an isomeric mixture. WebThe photo adsorption of ACP on TiO 2 is poor and depends on the light intensity. Other studies refer to the photo-hydrogenation of ACP. ... characterization such as adsorption, BET surface area, XRD and SEM showed that they are identical to commercial ZnO. Typical XRD and SEM image of ZnO used in the study are shown in figures 2A and B.
