Zn@ZrO2 nanoparticles decorated on naringin-based sensor for electrochemical detection of p-nitrophenol and o-nitrophenol

“…Zn@ZrO 2 /NG nanocomposites were synthesized based on our previously reported procedure, 20 with novelty in the modification part which was done in a single step. Three different concentrated Zn@ZrO 2 /NG nanocomposites, Zn@ZrO 2 /NG(1 : 5), Zn@ZrO 2 /NG(2 : 5), and Zn@ZrO 2 /NG(3 : 5), were synthesized.…”

“…17 The electrochemical response can be enhanced by modifying the surface of the electrode with an active substance, such as simple metal and metal oxide nanomaterials or nanocomposites. For example, Ag, 18 Au, 19 ZrO 2 , 20 ZnO, AgO 2 , 21 and Fe 2 O 4 22 nanomaterials have great electrochemical detection capability for nitrobenzene because they are excellent catalysts. ZrO 2 nanoparticles are the most suitable materials for immobilizing molecules with oxygen-containing compounds because of their stability at high temperature, inability to react with chemicals, nontoxicity, and strong attraction to oxygen-containing compounds.…”

“…These ZrO 2 nanoparticles also contain a three-dimensional platform with limited angles that can be changed to allow direct electron transfer between the protein and the conductor. 20 Owing to its appealing properties, ZrO 2 has been widely used in electrochemical sensors. Moreover, ZnO NPs are n-type semiconductors with a significant excited binding energy of 60 meV and a band gap value of 3.2 eV.…”

Green Chemistry Approach for One‐Step Synthesis of Iodinated Graphene Material for Supercapacitor Applications

“…Herein, we report an iodine‐incorporated graphene material in a one‐pot synthetic methodology by using NaIO 4 and m‐CPBA as oxidizing and iodinating agents at room temperature for supercapacitor application (Figure 1). NaIO 4 is effectively supported in the iodination and oxidation processes, and the effective deoxygenation of i‐GO takes place to produce i‐graphene when m‐CPBA is added to the mixture with H 2 SO 4 via an exothermic process [29] . The iodine functionality on the graphene surface increases the sheet d‐spacing, thereby enhancing the ion mobility and bolstering the cyclic stability of the graphene surface.…”

GCD, EIS, and CV studies showed that the i-graphene electrode material displayed a favorable capacitance.…”
