▎ 摘　　要

NOVELTY - Graphene (GN) oxide and calix(4)arene (T) are ultrasonically dissolved in deionized water, stirred, and hydrazine hydrate and ammonia are added to form mixed solution which is magnetically stirred to obtain black dispersion. Dispersion is centrifuged, and washed to obtain GN-T nanocomposite. obtained powder is dispersed in water, mixed with aqueous solution of gold nanoparticles and centrifuged to obtain GN-T-AuNPs solution. Obtained material is dried to obtain graphene-calix(4)arene-gold ternary nanoparticles (GN-T-AuNPs). USE - Preparation of graphene-calix(4)arene-gold ternary nanoparticles used as electrode in electrochemical reaction of methylene blue (claimed). ADVANTAGE - The method efficiently provides graphene-calix(4)arene-gold ternary nanoparticles, by simple method with low detection limit of 9x 10-9 mol.L-1. DETAILED DESCRIPTION - 10 mg Graphene (GN) oxide and 10 mg calix(4)arene (T) are ultrasonically dissolved in 10 ml deionized water, stirred at room temperature for 12 hours, and 100 mu l hydrazine hydrate and 200 mu l ammonia are added to form a mixed solution. The obtained mixed solution is magnetically stirred at 75 degrees C, and reacted for 14 hours, to obtain a black dispersion. The obtained black dispersion is centrifuged at the speed of 10000 rpm for 20 minutes, and washed thrice with deionized water to obtain GN-T nanocomposite which is then dried under vacuum at 65 degrees C for 48 hours to obtain GN-T powder. The obtained powder is then ultrasonically dispersed in water to obtain 1 mg/mL GN-T dispersion. The obtained dispersion is mixed with aqueous solution of gold nanoparticles (AuNPs), stirred, centrifuged at the speed of 10000 rpm for 10 minutes and washed with water to obtain GN-T-AuNPs solution. The obtained material is dried at 65 degrees C under vacuum for 48 hours, to obtain graphene-calix(4)arene-gold ternary nanoparticles (GN-T-AuNPs). An INDEPENDENT CLAIM is included for application of graphene-calix(4)arene-gold ternary nanoparticles.
