Four different TiO₂ modifications (P25, P90, PC105, and PC500) were screened for the reaction showing good performance for PC25 and PC500. PC500 was selected for a detailed kinetic study to find the optimal operating conditions, and to obtain a better understanding of the photocatalytic pathway in relation to conventional and transfer hydrogenation. The kinetic data were analyzed using the pseudo-first-order reaction rate law. A complete conversion was obtained for ACP concentrations below 1 mM using a 360 nm filter and argon as the purge gas within 2-3 hourRSC advancesPhotocatalytic hydrogenation of acetophenone on a titanium dioxide cellulose film.PMC8982184390540038Obata KSchwarze MThiel TASchomacker RAbdi FFvan de Krol RfalsePhotocatalytic hydrogenation of acetophenone on a titanium dioxide cellulose film.A previously developed sustainable immobilization concept for photocatalysts based on cellulose as a renewable support material was applied for the photocatalytic hydrogenation of acetophenone (ACP) to 1-phenyl ethanol (PE).
