چکیده

Monodispersed nickel phosphide (Ni2P) nanoparticles were for the first time applied to photocatalytic hydrogen evolution from lactic acid aqueous solution under visible light LED irradiation using CdS nanorods as a photosensitizer. The system exhibited high photocatalytic hydrogen-generating activity and excellent stability in aqueous acidic media.

Photocatalytic hydrogen evolution from carbon-neutral oxalate with 2-phenyl-4-(1-naphthyl)quinolinium ion and metal nanoparticles.

Photocatalytic hydrogen evolution has been made possible by using oxalate as a carbon-neutral electron source, metal nanoparticles as hydrogen-evolution catalysts and the 2-phenyl-4-(1-naphthyl)quinolinium ion (QuPh(+)-NA), which forms the long-lived electron-transfer state upon photoexcitation, as a photocatalyst. The hydrogen evolution was conducted in a deaerated mixed solution of an aqueous...

Spectacular photocatalytic hydrogen evolution using metal-phosphide/CdS hybrid catalysts under sunlight irradiation.

A highly efficient and robust heterogeneous photocatalytic hydrogen evolution system was established for the first time by using the CoP/CdS hybrid catalyst in water under solar irradiation. The H2-production rate can reach up to 254,000 μmol h(-1) g(-1) during 4.5 h of sunlight irradiation, which is one of the highest values ever reported on CdS photocatalytic systems in the literature.

Photocatalytic Degradation of Safranin ‎Dye from Aqueous Solution Using Nickel ‎Nanoparticles Synthesized by Plant ‎Leaves

   In this paper, a facile and eco-friendly method for the preparation of Ni nanoparticles (Ni NPs) has been described based on the bioreduction of aqueous Ni(II) precursors with Phlomis cancellata Bunge extract. UV-visible spectrum of the aqueous medium containing Ni nanoparticles showed a peak of 390 nm. Since the experimental conditions of this procedure play vital roles in the synthesis...

Metal-free hydrogen evolution with nanoparticles derived from pyrene via two-photon ionization induced by laser irradiation.

Laser irradiation of a cyclohexane solution containing pyrene resulted in hydrogen evolution as pyrene was converted to a metal-free nanoparticle photocatalyst. When C6H12 was replaced by C6D12, D2 was mainly evolved. This result suggests that the hydrogen source is cyclohexane used as a solvent. Photocatalytic hydrogen evolution was also observed in an aqueous solution by using a water-soluble...
