Pictorial representation of all possible dye degradation reaction in UV light initiated indirect mechanism. This mechanism is practically more important over visible direct
Pd–Ag bimetallic and monometallic nanoparticles were decorated on g-C<sub>3</sub>N<sub>4</sub>and evaluated for their ability to produce H<sub>2</sub>through water splitting reactions.
The ever‐increasing resistance of plant microbes towards fungicides and bactericides has been causing serious threat to production in recent years. For the development an effective antifungal agent, we introduce a novel hydrothermal protocol for synthesis chitosan iron oxide nanoparticles (CH‐Fe 2 O 3 NPs) using acetate buffer low pH 5.0 intermolecular interaction Fe NPs CH. composite structure elemental elucidation were carried out by X‐ray power diffraction (XRD), Scanning Electron...

Here we demonstrate a new strategy of boosting the photocatalytic activity titania (P25) for H2 production from water splitting reaction by depositing palladium/strontium nanoparticles, forming Pd/Sr-NPs@P25. The Pd/Sr-NPs are in situ prepared on surface P25. effects Pd and Sr reactions further revealed. Strontium form strontium oxide promotes electron transfer semiconductor to palladium nanoparticles increasing Fermi level P25 support. structural morphological characterizations...
High activity, a low rate of CO poisoning, and long-term stability Pd electro-catalysts are necessary for practical use as an anode material in direct formic acid fuel cells. Achieving high degree nanoparticle dispersion on carbon support, without agglomeration, while maintaining facile electron transfer through the catalyst surface two challenging tasks to be overcome fulfilling this aim. Herein, we report effect addition La/La-oxides efficiency nanoparticles supported reduced graphene...
Abstract A series of Cu(OH) 2 –Ni(OH) /P25 photocatalysts was prepared by co‐deposition–precipitation (total metal loading ≈1 wt %) and their performance evaluated for H production. Among this series, the 0.8 –0.2 Ni(OH) photocatalyst demonstrated very high production rates in 20 vol % ethanol/water 5 glycerol/water mixtures (10 22 mmol h −1 g , respectively). Detailed analyses based on reaction kinetics, photoluminescence, X‐ray photoelectron spectroscopy (XPS), charge carrier scavenging...

Development of non-noble metal photocatalysts for hydrogen (H2) generation from renewables is important towards cost effective technology. Titania nanorods with different phase compositions and surface areas were fabricated by calcination titanate (H2Ti3O7) precursors obtained treating P25 (TiO2) hydrothermally in 10 M NaOH followed HCl washing. Subsequently the copper nickel hydroxides co-deposited over TiO2 used to generate H2 alcohol-water mixtures under UV light. Among synthesized...
Photoreforming biomass-derived waste such as glycerol into hydrogen fuel is a renewable generation technology that has the potential to become important due unavoidable CO2 production during methane steam reforming. Despite tremendous efforts, challenge of developing highly active photocatalysts at low cost still remains elusive. Here, we developed novel photocatalyst with hybrid support comprising reduced graphene oxide (rGO) and TiO2 nanorods (TNR). rGO in not only performed an excellent...
