基于离子液体功能化碳纳米管负载金-铂纳米粒子的过氧化氢传感器
A hydrogen peroxide sensor based on Au-Pt nanoparticles loading to ionic liquid functionalized multiw alled carbon nanotube
摘要
Abstract
A novel hydrogen peroxide(H2 O2 ) sensor is fabricated by electrodepositing Au‐Pt nanoparticles (NPs ) on ionic liquid functionalized multiwalled carbon nanotube (MWCNTs‐IL ) composites . The modified electrode is characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS ) , respectively , and its electrochemical performance is greatly enhanced due to the presence of bimetallic nanoparticles . Under the optimal conditions , the peak current of hydrogen peroxide is proportional to its concentration in the range of 1 .0 × 10-9 ~1.2 × 10-7 mol·L -1 with the detection limit of 4 × 10-10 mol·L -1 .关键词
