Efficient generation of active oxygen-related radicals plays an essential role in boosting advanced oxidation process. To promote photocatalytic for gaseous pollutant over g-C3N4, a solid-gas interfacial Fenton reaction is coupled into alkalinized g-C3N4-based photocatalyst to effectively convert H2O2 radicals. This system includes light energy as power, situ and robust generator, surface-decorated Fe3+ trigger conversion, which attains highly efficient universal activity photodegradation...

Hydrogenation reactions are industrially important that typically require unfavorably high H2 pressure and temperature for many functional groups. Herein we reveal surprisingly strong size-dependent activity of Pt nanoparticles (PtNPs) in catalyzing this reaction. Based on unambiguous spectral analyses, the size effect has been rationalized by d-band electron structure PtNPs. This understanding enables production a catalyst with 1.2 nm, which shows sixfold increase turnover frequency 28-fold...
