利用非贵金属等离子体Al修饰TiO2/Cu2O异质结以提高光电催化分解水性能
本文利用具有表面等离子体共振(SPR)效应的Al对TiO2/Cu2O核/壳异质结进行改性,制备了TiO2/Cu2O/Al/Al2O3光电阳极.SEM和TEM等结果显示已成功合成核/壳异质结.UV-vis吸收光谱和UPS测试计算表明,Cu2O不仅可以显著扩展电极的吸光范围,且计算所得TiO2和Cu2O导价带位置验证了p-n异质结的合成.结合光电流、EIS等测试,证明了异质结能够有效地促进光生载流子的分离和转移.同时,在光照激发下,UV-vis吸收光谱在550nm出现明显的特征峰,表明Al的SPR效应被成功激发.Al纳米颗粒的SPR效应不仅可以产生热电子,并能够增强与异质结界面处的电场.之后,通过Mott-Schottk测试和Bode图,较为直观地说明了异质结和SPR效应的协同作用能够增加载流子的浓度,抑制电子空穴的复合,使所制备的TiO2/Cu2O/Al/Al2O3光电阳极表现出良好的光电性能,其光电流达到了4.52mA/cm2(1.23V vs.RHE),是TiO2/Cu2O异质结的1.84倍.相比于同样具有SPR效应的Au,Ag等贵金属而言,Al不仅价格低廉,而且在空气中自发形成的超薄Al2O3薄膜能够有效地抑制Al的进一步氧化,并作为保护层能够显著提高电极的稳定性.在对样品稳定性的测试中,由于Al2O3保护层的存在,电极的稳定性提高了53%.本文对样品的实验测试和原理分析表明了异质结和非贵金属Al的SPR效应的协同作用显著提高了光电极的光电性能,为设计具有良好性能和高实用性的电极提供了新思路.
