Hidrojen Çıkış Reaksiyonu İçin Bakır-Çinko ve Bakır-Demir İkili Kaplama
Yüksek hidrojen gelişim reaksiyonu (HER) için dayanıklılık aktivitesine sahip farklı kaplamalar elektrokimyasal kaplama yöntemi ile hazırlanmıştır. Demir, bakır ve çinko alaşımları grafit elektrot üzerine çöktürüldü. Grafit elektrotu üzerine ikili kaplamalar hazırlanmıştır. Çinko alaşımları, HER' de kullanım için uygun gözenekli ve elektrokatalitik bir yüzey oluşturmak için alkali çözeltide aşındırılmıştır. Yüzey karakterizasyonu için taramalı elektron mikroskobu (SEM) kullanılmıştır. Elektroliz, DC güç kaynağı ile 1,0 M KOH çözeltisi içinde gerçekleştirilmiştir. Kimyasal karakterizasyon için katodik akım-potansiyel eğrileri, elektrokimyasal impedans spektroskopisi ve dönüşümlü voltametri ölçümleri yapılmıştır. Deneysel sonuçlar, aşındırılmış çinko alaşımlarının, HER için diğer elektrotlara kıyasla, fiziksel istikrarı iyi olan kompakt ve gözenekli yapılara sahip olduklarını göstermektedir.
Copper – Zinc and Copper-Iron Binary Electrode for Hydrogen Evolution Reaction
The different coatings with high hydrogen evolution reaction (HER) durability activity were prepared byelectrodeposition. Iron, copper and zinc alloys were deposited on graphite electrode. The binary coatingprepared on the graphite electrode. Zinc alloys were etched in alkaline solution to produce a porous andelectrocatalytic surface suitable for use in the HER. The scanning electron microscopy (SEM) was used forsurface characterization. Electrolysis was carried out in 1.0 M KOH solution by DC power supply. Cathodiccurrent–potential curves, electrochemical impedance spectroscopy and cyclic voltammetry measurementswere performed for chemical characterization. The experimental results show that the etching zinc alloyshave compact and porous structures with good physical stability in comparison with other deposit for HER.
