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.

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.
