Single-Atom Catalysts on CN: Minimizing Single Atom Pt Loading for Maximized Photocatalytic Hydrogen Production Efficiency.

The use of metal single atoms (SAs) as co-catalysts on semiconductors has emerged as a promising technology to enhance their photocatalytic hydrogen production performance. In this study, we describe the deposition of very low amounts of Pt SAs (<0.1 at %) on exfoliated graphitic carbon nitride (CN) by a direct Pt-deposition approach from highly dilute chloroplatinic acid precursors.

TiO/AgO immobilized on cellulose paper: A new floating system for enhanced photocatalytic and antibacterial activities.

Paper-TiO-AgO floating photocatalysts were produced under mild condition and their photocatalytic activity for the degradation of aromatic amine under sunlight stimulant was investigated. Characterizations by Raman, XRD, XPS, DRS and PL confirmed the presence of TiO and AgO, and the morphology of the appended TiO/AgO layer was probed by FE-SEM. The photocatalytic activity of the prepared samples was investigated by the degradation of aniline (AN) in water under simulated sun-light illumination and constrained conditions, i.
