Facile synthesis of a zeolitic imidazolate framework-8 with reduced graphene oxide hybrid material as an efficient electrocatalyst for nonenzymatic H2O2sensing

Abstract: A zeolitic imidazolate framework-8 (ZIF-8)/reduced graphene oxide (rGO) nanocomposite was formed by using an efficient synthetic method.

“…The LOD was calculated as 3.1 × 10 –8 mol/L (S/N = 3). As shown in Table , , the proposed mimic peroxidase sensor (PGA/PCN-222­(Mn)/GCE) showed excellent electrochemical performances in terms of wider linear range, higher sensitivity, and lower LOD. Compared with Cu-MOF/GCE, the PGA/PCN-222­(Mn) composite film-modified GCE had distinct advantages over ultralow LOD and exceptional stability, which is suitable to analyze H 2 O 2 at low concentrations with a longer cycle life.…”

“…The 64.46% loss in ZIF-8 is due to the complete removal of the adsorbed methanol and water molecules from the cavities, and the breakdown of the Hmim framework to form a stable white ZnO solid in the temperature range of 530-850 °C. 59 The TGA and DTG curves of the BIZ material are similar to those of ZIF-8 but at much lower levels. This is due to the low percentage of ZIF-8 in the BIZ composition and the attachment of ZIF-8 particles on the Bi 2 MoO 6 plates could stabilize the ZIF-8 structure.…”

“…As is known, many species such as AA, DA, UA and some carbohydrates will produce interference signals in the process of detecting H 2 O 2 , which makes the selectivity of H 2 O 2 sensors a huge challenge. 15,53 As shown in Fig. 8, the anti-interference study of ZnO@ZIF-8 nanorod arrays is carried out by recording the current response of continuous injection of DA, AA, UA, GO, lysine and NaCl.…”

“…Due to their ordered structure, metal–organic frameworks (MOFs) as new multi-void crystalline materials have a large internal surface area. 15–17 Recently, MOFs have been used to produce core–shell structures by encapsulating metal oxides. 18 The obtained metal oxide@MOF materials exhibit novel physical and chemical properties in various sensor applications because of the unique molecule-screening functions of the MOF shells.…”
