Distance–based Paper Sensor for Determination of Chloride ion Using Silver Nanoparticles

03-Jul-2018 | Kamonchanok Phoonsawat; Nalin Ratnarathorn; Charles Henry; Wijitar Dungchai, Analyst, 2018

We report the first development of a distance-based paper sensor for a simple, inexpensive, instrument-free, and portable determination of chloride ions. Our analysis reaction is based on the oxidative etching of silver nanoparticles (AgNPs) to form AgCl in the presence of Cl⁻ and H2O2. The H2O2 ...

Precursor-mediated synthesis of Cu2−xSe nanoparticles and their composites with TiO2 for improved photocatalysis

03-Jul-2018 | Sweta Gahlot; Erwann Jeanneau; Frederic Dappozze; Chantal Guillard; Shashank Mishra, Dalton Transactions, 2018

The direct synthesis of copper selenide nanoparticles from the reaction of ditertiarybutyl selenide tBu2Se with copper(ii) trifluoroacetate Cu(TFA)2 under mild conditions is reported. The isolation of a molecular species during the course of this reaction, established as [Cu2(TFA)2(tBu2Se)3], by ...

Synthesis of zero-valent iron nanoparticles via laser ablation in a formate ionic liquid under atmospheric conditions

03-Jul-2018 | Shinya Okazoe; Yoshiro Yasaka; Masaki Kudo; Hiroshi Maeno; Yasukazu Murakami; Yoshifumi Kimura, Chemical Communication, 2018

Transition metal nanoparticles (NPs) are promising materials for use as catalysts in many processes, although they are easily oxidized under ambient conditions. In this communication, a novel synthetic method is proposed for producing zero-valent iron (Fe) NPs by laser ablation under atmospheric ...

Electromagnetic Interference (EMI) shielding performance of lightweight Metal decorated Carbon nanostructures dispersed Polyvinylidene fluoride flexible films

03-Jul-2018 | Kumaran - Rengaswamy; Dinesh Kumar Sakthivel; Alagar Muthukaruppan; N. Balasubramanian; Subramanian Venkatachalam; ..., New Journal of Chemistry, 2018

We report electromagnetic interference shielding of metals decorated MWCNT/rGO in polyvinylidene fluoride (PVDF) flexible films. X-ray diffraction patterns show the presence of metallic nanoparticles firmly bound with carbon fillers of the composite. The morphological studies proved the ...

Dual mode detection of amifostine based on gold nanoparticles and sulfanilic acid functionalized graphene quantum dots

03-Jul-2018 | Ning Li; Weidan Na; Hua Liu; Xingguang Su, New Journal of Chemistry, 2018

In this work, we developed a versatile dual-readout (colorimetric and fluorometric) amifostine (WR2721) sensor based on the inner filter effect (IFE) of gold nanoparticles (AuNPs) on sulfanilic acid functionalized graphene quantum dots (SGQDs). The fluorescence of SGQDs can be adequately ...

Unexpected Refacetting of Palladium Nanoparticles under Atmospheric N2 Condition

03-Jul-2018 | Xun Zhang; Jun Meng; Beien Zhu; Wentao Yuan; Hangsheng Yang; Ze Zhang; Yi Gao; Yong Wang, Chemical Communication, 2018

We demonstrate an unexpected refacetting process of Pd nanoparticles induced by N2 under atmospheric pressure at elevated temperature by in situ TEM observation. The morphology change with a notable increase of Pd {110} facets fraction was visualized by the atomic-scale TEM images and further ...

Enhanced photocatalytic performance and stability of visible-light-driven Z-scheme CdS/Ag/g-C3N4 nanosheets photocatalyst

03-Jul-2018 | Yingying Qin; Hong Li; Hongjun Dong; Changchang Ma; Xiuying Li; Xinlin Liu; Yang Liu; Chunxiang Li; Yongsheng Yan, New Journal of Chemistry, 2018

A novel Z-scheme CdS/Ag/g-C3N4 nanosheets photocatalyst was synthesized by combining the hydrothermal and photo-deposition techniques, where Ag nanoparticles as carrier transport channels significantly improve the separation efficiency of electron–hole pairs. Outstanding photocatalytic activity ...
