Photocatalytic hydrogenation of acetophenone on a titanium dioxide cellulose film

Abstract

The photocatalytic hydrogenation of acetophenone to 1-phenylenthanol was investigated with cellulose-immobilized titanium oxide (TiO2) particles.

Insights into the Solvent Effect on the Synthesis of Pd@PC-COFs for Phenol Hydrogenation

“…The mapping images further confirm the agglomeration and inhomogeneous distribution of Pd NPs in Pd@PC-COF-Pen (Figure a). In Pd@PC-COF-NBA, EA, and Dio, Pd NPs are uniformly distributed on the PC-COFs, suggesting that the appropriate impregnation solvent is beneficial for the dispersion of Pd NPs. , …”

“…In Pd@PC-COF-NBA, EA, and Dio, Pd NPs are uniformly distributed on the PC-COFs, suggesting that the appropriate impregnation solvent is beneficial for the dispersion of Pd NPs. 40,59 The surface elements and their chemical states of catalysts are important parameters affecting the catalytic performance of catalysts. Six typical catalysts Pd@PC-COF-Pen, Pd@PC-COF-PE, Pd@PC-COF-NBA, Pd@PC-COF-EA, Pd@PC-COF-Dio, and Pd@PC-COF-MeOH after one reaction cycle were characterized by X-ray photoelectron spectroscopy (XPS).…”

Screening of Heterogeneous Photocatalysts for Water Splitting

“…As part of the photocatalyst screening, the immobilization should be easy, fast, and reproducible. Recently, a method was developed for photocatalyst immobilization based on cellulose as a binder [16,17]. There are two possibilities for immobilization: a) the photocatalyst is immobilized on the surface of a filter paper with cellulose, and b) the photocatalyst and the cellulose form a composite membrane.…”

“…As cellulose is generally not dispersible in polar solvents like water or methanol, it was treated with sulfuric acid as described in the experimental part. Such an immobilized photocatalyst is active, e.g., for hydrogen production via water splitting [16] or photocatalytic hydrogenation of acetophenone [17].…”
