Synthesis and characterization of LaMnO3 nanocrystals and graphene oxide: fabrication of graphene oxide–LaMnO3 sensor for simultaneous electrochemical determination of hydroquinone and catechol

“…Electrochemical methods have some attractive advantages such as simple and fast response, low maintenance cost, excellent selectivity and high sensitivity. However, a serious obstacle is that the oxidation peak potentials of the isomers are too close at a bare electrode which causes overlapping of voltammetric responses, making their discrimination very difficult [13][14][15][16][17]. A chemically modified electrode is a superior approach to solve the peak separation problem by applying a modifier [18][19][20][21][22][23][24].…”

“…To overcome these shortcomings, many researches have been focused on the synthesis of graphene-based inorganic composites. Recently, the synthesis procedures of new composites of graphene with inorganic particles, such as metal, metal oxide, metal hydroxide, or metal sulfide particles, have been reported [33][34][35][36][37][38]. Due to presence of graphene and inorganic particles, the fabricated electrochemical sensors display exceptional improvement in electrical properties and functionality for different types of composites.…”

Application of Fe3O4@SiO2/GO nanocomposite for sensitive and selective electrochemical sensing of tryptophan

“…In order to improve the efficiency of usual electrodes for sensor applications, a conventional modification method is applied. Modified electrodes not only render better electrocatalytic activity, higher sensitivity and selectivity, but also lower detection limit in comparison with traditional electrodes [19][20][21][22][23][24][25][26].…”
