在液体的照射下观察到新的光电化学过程|液体|N，N，N′，N′-四己基对苯二胺（THPD）微滴沉积在基底平面热解石墨电极上并浸入电解质水溶液中时，固体三重界面。在中性THPD的存在下，阴极光响应，并在THPD+的存在下，阳极光响应与阴离子依赖的特性，观察。在电极表面的中间覆盖处观察到的光电流中的最大值表明三重界面THPD|电极|含水电解质是反应区。这是第一次报告的光电化学过程在这种类型的接口。
Novel photoelectrochemical processes are observed upon irradiation of the liquid|liquid|solid triple interface at microdroplets of N,N,N′,N′-tetrahexyl-para-phenylenediamine (THPD) deposited onto a basal plane pyrolytic graphite electrode and immersed in aqueous electrolyte solution. In the presence of neutral THPD, cathodic photo responses, and in the presence of THPD+, anodic photo responses with anion-dependent characteristics, are observed. A maximum in the photocurrents observed at intermediate coverage of the electrode surface suggests that the triple interface THPD|electrode|aqueous electrolyte is the reaction zone. This is the first report of photoelectrochemical processes at this type of interface.
