Ultrasensitive hydrazine sensor fabrication based on Co-doped ZSM-5 zeolites for environmental safety

Abstract

Various Co-loaded ZSM-5 zeolites (Co-ZSM-5) were prepared and the details of their structural, morphological and elemental properties characterized by different conventional methods.

An Alternative Electrochemical Approach to Detect 4-Nitrophenylhydrazine With ZnO/SnO2 Nanoparticles Decorated Glassy Carbon Electrode

“…Due to the increasing the industrial activities, the water-soluble aromatic derivative of hydrazine coming from the untreated industrial e uent such as dyes, pesticides, photographic, plant-growth regulators, pharmaceuticals, colour and pigment industries. Besides this, the aromatic hydrazines use in explosive, rocket fuel and spacecraft fuel [25,26]. The aromatic and aliphatic both hydrazine are poisonous for plants, animals, human and aquatic lives.…”

“…Therefore, a reliable technique for the detection of hydrazine (4nitrophenylhydrazine) is necessary. In recent, many kinds of research have been conducted based on CoS2-CNT nanocomposites [26], SrO.CNT NCs [27], Fe2O3 NPs [28], Co-doped ZSM-5 zeolites [25], TiO2 nanoparticles [32], Fe2O3/CeO2 nanocubes [33] and ZnO nano-urchins [29] coated on GCE for precious hydrazines detection ( both aromatic and aliphatic) applying electrochemical (I-V) approach. This experimental work performed to assemble a sensor in I-V approach selective to 4-NPHyd with ZnO/SnO2 NPs coated on GCE.…”

CoFe2O4 Nanocrystals Mediated Crystallization Strategy for Magnetic Functioned ZSM‐5 Catalysts

“…Zeolites, a kind of microporous crystalline aluminosilicates, have been widely applied in the fields of adsorption, separation, and catalysis in petrochemical and chemical industry . Aiming to the functionalization of host zeolite matrixes, various guest species are added into the precursor of zeolites, in which the nucleation and growth of zeolite crystals occur together with guest species . Chen and co‐workers have successfully introduced Pd nanoparticles inside mesoporous MFI zeolite nanocrystals through a modified Kirkendall growth process.…”
