TiO2 and Pd/TiO2 as Photocatalysts for Hydrogenation of Ketones and Perspective of Membrane Application

Abstract

Among the main chemical transformations, currently applied in industrial practices, reduction processes, such as the reduction of carbonyl compounds in the corresponding alcohols, play an important role in organic synthesis [1-3]. In particular, acetophenone (AP) hydrogenation has been widely studied since the resultant reduction product, 1-phenylethyl alcohol or also phenyl ethanol (PE), is a common precursor for the preparation of analgesic and anti-inflammatory drugs as well as fragrances and perfumes [4-6].
