Cu/NiCoBi Elektrotun Hidrojen Gazı Eldesinde Katot Olarak Kullanımı ve Katalitik Etkisinin Zamanla Değişiminin Belirlenmesi
Abstract
Bu
çalışmada bakır (Cu) yüzeyinde elektrokimyasal yöntemle nikel-kobalt-bizmut
(NiCoBi) üçlü kaplama oluşturulmuş (Cu/NiCoBi) ve alkali suyun elektrolizi ile
hidrojen gazı eldesindeki performansı incelenmiştir. Bu amaçla; hidrojen aşırı
gerilimleri, hidrojen gazı hacimleri, katodik polarizasyon ölçümleri ve farklı
aşırı gerilimlerde elektrokimyasal impedans spektroskopisi (EIS) ölçümleri elde
edilmiştir. Elektrotların elektrokatalitik etkilerinin zamanla değişiminin
belirlenmesi için elektroliz hücresine 168 saat boyunca 100 mA cm-2
sabit akım yoğunluğu uygulanmıştır ve farklı zaman aralıklarında
elektrokimyasal ölçümler gerçekleştirilmiştir. Elde edilen bulgulara göre; Cu/NiCoBi elektrotun hidrojen aşırı gerilimi,
Cu ve diğer ikili kaplamalardan (Cu/NiCo, Cu/NiBi) oldukça düşüktür. Cu/NiCoBi
elektrot 168 saatlik elektroliz süresi boyunca etkinliğini korumuştur.
