Synthesis of Pt/ionic liquid/graphene nanocomposite and its simultaneous determination of ascorbic acid and dopamine

Synthesis of graphene/methylene blue/gold nanoparticles composites based on simultaneous green reduction, in situ growth and self-catalysis

“…Due to these fantastic properties, AuNPs have been extensively used as rGO decorators [19,30,31]. To date, most composites that combine rGO with AuNPs were synthesized through co-reduction of the precursors, chloroauric acid (HAuCl 4 ) and GO, by chemical reductants, such as sodium borohydride (NaBH 4 ) and hydrazine (N 2 H 4 ) [32][33][34]. Although this method is popular, its primary disadvantage is the use of highly toxic reductants (NaBH 4 , N 2 H 4 ) [35].…”

Electrochemical determination of Sudan IV in food samples by using graphene-modified glassy carbon electrodes

“…The functional groups of C-OH and C-O-C cannot be reduced by sodium borohydride. 15,21 The existence of these hydrophilic groups provides a means to disperse rather than dissolve in solvent. Figure 2 shows the SEM image of the graphene film on the GCE, revealing the crumpled and wrinkled structure of the graphene film on the electrode.…”

Sodium Alpha Olefin Sulfonate Modified Carbon Paste Electrode Sensor for Dopamine: A Voltammetric Study

“…The DA can be detected using electrochemical techniques due to its good electro active nature. Therefore, the electrochemical methods for quantifying the amount of DA in human body fluids have attracted more attentions due to its high accuracy, fast response and bulk modification with simple instruments [20][21][22][23][24][25][26][27][28][29][30].…”
