Using a solvent‐free method, zeolite NaA was synthesized from raw kaolin, collected Binh Duong, Vietnam. The synthesis involved thermal hydration under an alkaline solution. catalysts based on binary nickel‐silver nanoparticles were prepared through in situ reduction of metal salts aqueous zeolitic suspension using sodium borohydride as reducing agent. fully characterized by various techniques such X‐ray diffraction (XRD), Fourier transform infrared (FT‐IR), scanning electron microscopy...
2‐(2‐bromoaryl)‐4,7‐dimethoxy‐1 H ‐benzo[ d ]imidazoles and ( Z )‐2‐(2‐bromovinyl)‐4,7‐dimethoxy‐1 react with 1,3‐diketones by microwave irradiation in DMF the presence of a catalytic amount recyclable Fe 3 O 4 @SiO 2 @MOF‐199 along base to give binuclear isoquinoline‐ pyridine‐fused benzimidazoles, respectively. Treatment such N‐fused hybrid scaffolds ceric ammonium nitrate acetonitrile/H or HBr/FeCl affords benzimidazole‐4,7‐diones good high yields.
2‐(2‐Bromoaryl)indoles react with 2‐aminoazoles by microwave irradiation in DMF the presence of a catalytic amount CuI and base to produce trinuclear N‐fused hybrid scaffolds, benzo[4,5]imidazo[1,2‐ ]indolo[1,2‐ c ]quinazolines imidazo[1,2‐ moderate good yields.

Carbon-supported nanocatalysts palladium-vanadium-cobalt (PdVCo) were synthesized via ethylene glycol (EG) reduction reaction and NaBH 4 -assisted reduction. The electrocatalytic performance for alcohol oxidation in alkaline solutions was investigated. XRD EDX results confirmed the incorporation of V Co with Pd lattice to form ternary PdVCo a single phase. EG process exhibited highly dispersed nanoparticles uniform size, electrochemical surface area (ECSA) determined by cyclic voltammetry 1...
Introduction: Chlorophenols (CPs) have become prevalent in the manufacture of herbicides, fungicides, pesticides, insecticides, pharmaceuticals, and dyes, contributing significantly to water pollution. Addressing this challenge, various treatment methods such as incineration, electrochemistry, photochemistry, biotechnology, catalytic hydrodechlorination been explored reduce toxic chlorophenol contaminants. Hydrodechlorination stands out an efficient technique for removal chlorine atoms. The...
M ultimetallic nanocatalysts have remarkably revealed activities in various catalytic applications. Herein, the ternary based on palladium-vanadium-cobalt were successfully synthesized through reduction of their salts with combination sodium borohydride and ethylene glycol as reducing agents, including impregnating activated carbon (AC) substrate colloid solution metallic nanoparticles (PdVCo/C). The immobile trimetallic PdVCo AC was evidenced by XRD, EDX analysis, transmission electron...
