SYNTHESIS AND CHARACTERIZATION OF HIGH ENTROPY OXY-HYDROXIDES FOR ELECTROCATALYTIC OXYGEN EVOLUTION AND REDUCTION REACTION
Öz: The need for energy is rising quickly, and the usage of fossil fuels is contributing to the greenhouse effect and environmental pollution, both of which are raising public concerns. The development of novel electrochemical energy storage techniques as well as the creation of cleaner, more sustainable energies have both become highly researched topics as a result of this condition. New functional materials are being investigated for the advancement of energy storage. High entropy hydroxides (HEH) have lately been emerged as promising electrocatalyst for universal water splitting reactions, which are central for solid oxide fuel cells, hydrogen production and metal-air batteries. In this work, a cost-effective and scalable fabrication method was applied to fabricate several HEH on Nickel foam through single-step electrodeposition technique. Results showed that high-entropy FeCoNiMnOOH exhibits excellent OER activity with a low overpotential of 151 mV at current density of 100 mA cm−2, which is associated with it’s defective structure.
Anahtar Kelime: YÜKSEK ENTROPİLİ OKSİ-HİDROKSİTLERIN ÜRETİLMESİ, KARAKTERİZASYONU VE OKSİJEN ÇEVRİM REAKSİYONU ELEKTRO KATALİZÖRÜ OLARAK UYGULANMASI
Öz: Artan enerji talebini karşılamak ve çevre kirliliği endişelerini azaltmak için yenilenebilir enerji sistemleri ve verimli enerji dönüşüm cihazları kullanmak, yeni elektrokimyasal enerji depolama sistemleri geliştirmek gerekmektedir. Bu bağlamda, hidrojen üretimi, kati yakıt hücreleri ve metal-hava bataryaları gibi yeni nesi enerji üretme ve depolama sistemlerinde oksijen cevrim reaksiyonları sistemlerin performanslarında önemli rol oynamaktadır. Dolayısı ile bu reaksiyonları hızlandırmak için yeni fonksiyonel malzemeler araştırılmaktadır. Yüksek entropili hidroksitler, son zamanlarda, katı oksit yakıt hücreleri, hidrojen üretimi ve metal-hava pilleri için merkezi olan evrensel su ayırma reaksiyonları için umut verici bir elektrokatalizör malzemesi olarak on plana çıkmıştır. Bu çalışmada, tek adımlı elektrodepozisyon tekniği ile Nikel köpük üzerinde farklı kompozisyonlarda yüksek entropili hidroksitler’ in direkt üretimi araştırılmıştır. Elde edilen elektrokatalizorlerin elektrokimyasal performanslarına üretim voltaji, suresi ve elementel etki incelenmiştir. Sonuçlar, yüksek entropili FeCoNiMnOOH' un 100 mA cm-2' lik akım yoğunluğunda 151 mV' lik düşük bir aşırı potansiyeli sergilediğini göstermiştir. FeCoNiMnOOH yüksek oksijen oluşum reaksiyonu katalitik aktivitesi ise yapıda bulunan oksijen hataları ile ilişkilendirilmiştir
