Simplistic approach to formulate an ionophore-based membrane and its study for nitrite ion sensing.

A polymeric membrane based on a ,'-bis(salicylidene)ethylenediaminocobalt(ii) complex as a cobalt ionophore (CI) was fabricated and optimized for nitrite ion sensing application. The membrane contained CI, 2-nitrophenyl octyl ether (2-NPOE) as a plasticizer and hexadecyl trimethyl ammonium bromide (HTAB) as a cationic additive in a polyvinyl chloride (PVC) matrix. The Nernstian slope (-0.

Solid state engineering of BiS/rGO nanostrips: an excellent electrode material for energy storage applications.

The study presents a novel, one-pot, and scalable solid-state reaction scheme to prepare bismuth sulphide (BiS)-reduced graphene oxide (rGO) nanocomposites using bismuth oxide (BiO), thiourea (TU), and graphene oxide (GO) as starting materials for energy storage applications. The impact of GO loading concentration on the electrochemical performance of the nanocomposites was investigated. The reaction follows a diffusion substitution pathway, gradually transforming BiO powder into BiS nanostrips, concurrently converting GO into rGO.

Nanostructured N doped TiO efficient stable catalyst for Kabachnik-Fields reaction under microwave irradiation.

Herein, we report nitrogen-doped TiO (N-TiO) solid-acid nanocatalysts with heterogeneous structure employed for the solvent-free synthesis of α-aminophosphonates through Kabachnik-Fields reaction. N-TiO were synthesized by direct amination using triethylamine as a source of nitrogen at low temperature and optimized by varying the volume ratios of TiCl, methanol, water, and triethylamine, under identical conditions. An X-ray diffraction (XRD) study showed the formation of a rutile phase and the crystalline size is 10 nm.

ZnCl loaded TiO nanomaterial: an efficient green catalyst to one-pot solvent-free synthesis of propargylamines.

One-pot green synthesis of propargylamines using ZnCl loaded TiO nanomaterial under solvent-free conditions has been effectively accomplished. The aromatic aldehydes, amines, and phenylacetylene were reacted at 100 °C in the presence of the resultant catalyst to form propargylamines. The nanocrystalline TiO was initially synthesized by a sol-gel method from titanium(iv) isopropoxide (TTIP) and further subjected to ZnCl loading by a wet impregnation method.

Herein, we synthesized ZnO nanorods using a solvothermal reaction technique at 200 °C for 24 h, and the prepared ZnO nanorods were decorated with silver (Ag) nanoparticles to enhance their photocatalytic activity. The Ag nanoparticles were photochemically deposited on the ZnO rods with varying molar concentrations (from 0.5 to 10 mol%), and their various physicochemical properties were studied.

The synthesis of orthorhombic nitrogen-doped niobium oxide (NbON) nanostructures was performed and a photocatalytic study carried out in their use in the conversion of toxic HS and water into hydrogen under UV-Visible light. Nanostructured orthorhombic NbON was synthesized by a simple solid-state combustion reaction (SSCR).
