Visible light-driven H2 production over highly dispersed Ruthenia on Rutile TiO2 nanorods [PDF]

, 2016
The immobilization of miniscule quantities of RuO2 (~0.1%) onto one-dimensional (1D) TiO2 nanorods (NRs) allows H2 evolution from water under visible light irradiation. Rod-like rutile TiO2 structures, exposing preferentially (110) surfaces, are shown to

Single‐Atom Photocatalyst as Floatable Artificial Leaf for Upcycling Oceanic Plastic Waste

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of oceanic plastic pollution, the novel Ru single atom loaded ZnIn2S4 photocatalysts, in the forms of powder or floatable artificial leaf, were prepared for direct conversion of raw polypropylene plastic into valuable chemicals. The optimized catalyst exhibits exceptional performance, with a total formic/acetic acid

Ga‐on‐In Substitution with Zn Vacancies in Zn3In2S6 Induces Electron–Hole Asymmetry and In─O Bond Weakening for Coupled Two‐Electron Oxygen Reduction and H2O2 Stabilization

Advanced Materials, EarlyView.
Ga‐on‐In substitution coupled with Zn vacancies in Zn3In2S6 creates a dopantdefect synergy that weakens InO bonding and induces electronhole asymmetry. The resulting spatial charge separation directs the two‐electron oxygen reduction pathway, enabling efficient artificial photosynthesis of H2O2 with a production rate of 187.8 µmol g−1 min−1 ...

Tunable Organic Photocatalysts for Visible-Light-Driven Hydrogen Evolution [PDF]

Journal of the American Chemical Society, 2015
Photocatalytic hydrogen production from water offers an abundant, clean fuel source, but it is challenging to produce photocatalysts that use the solar spectrum effectively. Many hydrogen-evolving photocatalysts are active in the ultraviolet range, but ultraviolet light accounts for only 3% of the energy available in the solar spectrum at ground level.
