Binary transition metal doping to create efficient TM–N–C electrocatalysts and enhance ORR catalysis under an external magnetic field

Electrochemical Sensor Based on Co-Doped FePS3 Nanosheets for Ultra-Sensitive Detection of Dopamine in Human Serum

“…Cobalt-doped FePS 3 materials exhibit superior catalytic properties compared to TMDs materials due to the bimetallic active site and the altered electronic structure of the active site (relative to the pure metal). 50 A Co@NCNTs/NC nanoparticle enzyme for DA detection was prepared by Lu et al 51 It is proposed that CoNPs can effectively boost the electrocatalytic properties of the material by reducing the charge transfer resistance and increasing the electrochemically active surface area, which is beneficial to the absorption of biomolecules during electrochemical sensing. 51 In this study, as shown in Scheme 1, we prepared FePS 3 with different proportions of Co doping using a low-cost salt template method, where inorganic salt as a template not only provides a large substrate for material growth, but also facilitates the chemical doping process.…”
