摘要 通过层层自组装方法,将荷正电的线性聚乙烯亚胺稳定的金溶胶纳米粒子和荷负电的Keggin结构的磷钨十二酸通过静电作用交替沉积在透明氧化锡(ITO)导电玻璃基底,石英玻璃基底和4 氨基苯甲酸(4 ABA)功能化的玻碳电极表面.用紫外 可见吸收光谱(UV/vis)、X 射线光电子能谱(XPS)以及循环伏安法(CV)监测了这种多层膜的生长过程,对其生长的均匀性、多层膜的组成和稳定性进行了表征,结果表明该多层膜不仅均匀稳定,而且对氧还原有较好的催化活性. Through layer-by-layer assembly, positively charged line-polyethylenimine (LPEI)-stabilized Au nanoparticles and negatively charged Keggin-type heteropolyacids H_3PW_(12)O_(40).nH_2O were alternately deposited on quartz and ITO substrates, and on a 4-aminobenzoic acid modified glassy carbon electrode. Thus-prepared multilayer films were characterized by UV-visible spectroscopy, X-ray photoelectron spectroscopy and cyclic voltammetry. The multilayer films are uniform and stable, and exhibit good elecrocatlytic activity for dioxygen reduction.
