【摘要】：以氯化钯(Pd Cl_2)为金属前驱体,乙醇为还原剂,聚乙烯吡咯烷酮(PVP)为稳定剂和导向剂,利用普通市售节能灯产生的光热作用,辅助制备多重栾晶钯纳米颗粒。用HRTEM、FFT、PXRD、XPS、UV-Vis和FT-IR等技术对产品的形貌、晶体结构、光学性质和稳定性进行了表征,并通过循环伏安法研究了多重栾晶Pd修饰玻碳电极对乙醇的电催化氧化活性。结果表明,多重栾晶钯结构的形成依赖于光和热的协同作用。该材料的表面等离子共振吸收峰在可见光区域,对乙醇有较好的电催化活性和抗中毒能力。
[Abstract]:Using palladium chloride PdCl2) as metal precursor, ethanol as reducing agent, polyvinylpyrrolidone (PVP) as stabilizer and guide agent, the photothermal effect of ordinary energy saving lamps was used. Multiplex Luan crystal palladium nanoparticles were prepared by assisted preparation. The morphology and crystal structure of the products were characterized by HRTEM-FFTFT-PXRDX UV-Vis and FT-IR techniques. The optical properties and stability were characterized, and the electrocatalytic oxidation of ethanol on glassy carbon electrode modified by multiplex Luan crystal PD was studied by cyclic voltammetry. The formation of multiplex Luan crystal palladium structure depends on the synergism of light and heat. The surface plasmon resonance absorption peak of the material is in the visible region, and it has good electrocatalytic activity and anti-poisoning ability to ethanol.
