Enhanced electrochemiluminescence from luminol at multi-walled carbon nanotubes decorated with palladium nanoparticles: a novel route for the fabrication of an oxygen sensor and a glucose biosensor.
将钯纳米颗粒(Pd-NPs)负载到多壁碳纳米管(MWCNTs)表面,制备纳米杂化材料 nanoPd-MWCNTs,并将其修饰玻璃碳电极(GCE),得到新型 ECL 电极。该修饰电极在中性介质中对鲁米诺–O2 和鲁米诺–H2O2 电致发光(ECL)反应表现出显著的电催化活性和敏化作用。基于鲁米诺–O2 体系,ECL 信号强度与溶解氧浓...
