Fabrication of hydrazine sensor based on silica-coated Fe2O3 magnetic nanoparticles prepared by a rapid microwave irradiation method

A Review on Iron Oxide‐Based Nanoarchitectures for Biomedical, Energy Storage, and Environmental Applications

“…The excellent electroactivity of this core–shell hybrid was attributed to the increased active sites and anti‐self‐aggregation properties of NiO NPs. In a related report, microwave‐synthesized Fe 2 O 3 @SiO 2 exhibited high sensitivity (12.658 µA m m −1 cm −2 ), wide linear range (2 × 10 −10 to 2.0 × 10 −3 m ), and impressive low detection limit (76 × 10 −12 m ) toward hydrazine, owing to the enhanced electron transfer between the active sites and coated electrode . The above studies clearly highlight the effective enhancement in sensitivity and detection limit of iron oxide‐based biosensors through hybridization, which may bring them a step closer toward practical use in food‐safety inspection and environmental‐pollution control.…”

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

“…The proposed Co-ZSM-5(150%-loading)/ GCE sensor has also shown better reliability and stability. 93 Despite these developments, there are still numerous important reservations that must be investigated more before the commercial production of this sensor.…”

A Novel Chemical Sensor Based on Sb2S3 Film for Highly Sensitive Detection of Hydrazine

“…Nowadays, a variety of materials have been applied to fabricate chemical sensors for detection of hydrazine due to their unique electrochemical and mechanical properties, such as zinc oxide (ZnO) , ferric oxide (Fe 2 O 3 ) , titanium dioxide (TiO 2 ) and manganese dioxide (MnO 2 ) . Antimony sulfide (Sb 2 S 3 ) is a well‐known binary semiconductor with infinite atom layers in its orthorhombic crystal structure .…”

“…Although it has been reported that the chemical sensors with the nanostructure possess an improved electrochemical performance in a certain extent, the synthesis of nanostructure is time‐consuming and energy‐wasting , which is not applicable for the low‐cost fabrication, especially using gold as supporting electrode . What's more, the nanostructure is always synthesized separately and the binder is needed to fabricate electrode , which is also not beneficial for the reproducibility and stability of chemical sensor. Therefore, it is desirable for developing a high‐performance, cost‐effective, stable, and reproducible chemical sensor to overcome above shortcomings.…”
