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.

The different coatings with high hydrogen evolution reaction (HER) durability activity were prepared by electrodeposition. Iron, copper and zinc alloys were deposited on graphite electrode. The binary coating prepared on the graphite electrode. Zinc alloys were etched in alkaline solution to produce a porous and electrocatalytic surface suitable for use in the HER. The scanning electron microscopy (SEM) was used for surface characterization. Electrolysis was carried out in 1.0 M KOH solution by DC power supply. Cathodic current–potential curves, electrochemical impedance spectroscopy and cyclic voltammetry measurements were performed for chemical characterization. The experimental results show that the etching zinc alloys have compact and porous structures with good physical stability in comparison with other deposit for HER.
