Abstract In this paper pH sensors based on tetra-metal oxide system (TMOF) film was synthesized by branched cathodic electrodeposition technique. Four different metal oxides mainly IrO2, RuO2, SnO2, and TiO2 used to form a film, which coated on various substrates such as titanium, steel, tin, and copper. The fabricated pH sensors underwent characterization and evaluation sensing performance. Characterizations results have indicated that titanium and steel substrates outperform alternative metal substrates Tin and copper. Nernstian performance of Steel and Titanium substrate with pH sensitivity ∼59 mV/pH remain the same, as well as tin and copper which are behaved as super-Nernstian with sensitivity ∼65 mV/pH. Fast response time ranged from 1 to 3 s were obtained. Perfect selectivity obtained using Na+, K+, Li+ and Mg2+ ions vs. primary one H+.

基于四金属氧化物体系的 pH 传感器在不同基板上通过支化阴极电沉积合成
摘要 本文采用支化阴极电沉积技术合成了基于四金属氧化物体系(TMOF)薄膜的pH传感器。四种不同的金属氧化物主要是 IrO2、RuO2、SnO2 和 TiO2 用来形成薄膜,它涂覆在各种基材上,如钛、钢、锡和铜。制造的 pH 传感器经历了表征和评估传感性能。表征结果表明,钛和钢基材的性能优于替代金属基材锡和铜。钢和钛基体的能斯特性能保持不变,其 pH 敏感性约为 59 mV/pH,锡和铜表现出超能斯特性能,灵敏度约为 65 mV/pH。获得了 1 到 3 秒的快速响应时间。使用 Na+、K+、Li+ 和 Mg2+ 离子与主要 H+ 离子相比获得了完美的选择性。
