Hydrothermal synthesis of NiFe₂O₄nanoparticles as an efficient electrocatalyst for the electrochemical detection of bisphenol A

Abstract

In this study, the sensitive and selective detection of bisphenol A (BPA) was achieved using a screen-printed carbon electrode (NFO/SPCE) modified with hydrothermally synthesized NiFe2O4 nanoparticles.

Core‐shell Hierarchical Enzymatic Biosensor Based on Hyaluronic Acid Capped Copper Ferrite Nanoparticles for Determination of Endocrine‐disrupting Bisphenol A

“…Although ferrite structures have been used as one of the components of various composite systems for the detection of analytes such as dopamine [62], pesticides [63], paracetamol [64] in recent years sensor designs containing BPA very few ferrite structures are encountered. As seen in Table 1, these structures generally didn't contain any modification process on their surfaces and they were not enzymatic systems [11,31b, 57]. BPA sensors containing enzymes, biopolymers and structures such as carbon black [15] or MWCNT [28] having toxic properties have been used.…”

“…10-325). The crystal size can be calculated using the Full-Width Half Maximum (FWHM) and the Scherrer formula [9,61]. Thus, the average crystal size of NiFe2O4 is 29.39 nm.…”

Magnetic materials for magnetoelectric coupling: An unexpected journey

“…One goal of NiFe2O4 research and development has been to identify simpler processing schemes that do not rely upon high-temperature treatments for inducing solid-state reactions. As a result several techniques have already been used to produce NiFe2O4 nanostructures, including hydrothermal reactions (Figure 20) (Kesavan et al, 2020), coprecipitation (Fa-Shen et al, 1988), combustion synthesis (Kooti and Sedeh, 2013), thermal decomposition (Karpova et al, 2012), sol−gel method (Pradeep et al, 2008), microwave processing (Köseoǧlu, 2013), electrospinning (Saensuk et al, 2015), reverse micelle technique (Kale et al, 2004), plasma deposition method (Nawale et al, 2011), radio frequency thermal plasma torch technique (Son et al, 2002), pulsed wire discharge (Yatsui, 2002), sonochemical synthesis (Lu et al, 2006), and high-energy milling (Šepelák et al, 2007(Šepelák et al, , Marinca et al, 2011. This last method can deliver nanocrystalline ferrites (and oxides in general) either by particle size reduction of bulk material to the nanometer scale without changes in its chemical composition or by inducing a heterogeneous solid-state chemical reaction between the ferrite precursors, i.e., by the mechanically induced formation reaction (mechanosynthesis) (Šepelák et al, 2007).…”
