N2  - Günümüzün en büyük problemlerinden biri, enerji gereksiniminin karşılanmasında çok büyük oranda fosil yakıtların kullanılmasıdır. Artan enerji ihtiyacının fosil yakıtlardan sağlanması, çevresel problemlere ve enerji maliyetinin artmasına neden olmaktadır. Bu problemlerin çözümü ancak sürdürülebilir enerji kaynakları kullanımıyla gerçekleştirilebilecektir. Bu yüzden bol miktarda bulunan hidrojen, temiz ve ideal bir yakıt olarak geleceğin enerji kaynağı olarak düşünülmektedir. Hidrojen gazı üretiminin en basit yolu suyun elektrolizidir. Suyun elektrolizi ile hidrojen üretiminde karşılaşılan en büyük problem, elektrokimyasal sistemde oluşan aşırı gerilim nedeniyle maliyet artışıdır. Bu çalışmada suyun elektrolizi ile hidrojen elde etmek amacıyla ucuz bir materyal olarak seçilen alüminyum elektrodun yüzeyi, önce polianilin (PAni)-Kitosan kompozit yapısıyla modifiye edilmiş, daha sonra elde edilen bu kompozit yapı üzerine hidrojen oluşumunda yüksek katalitik aktivite gösteren altın (Au) nanopartiküller ayrıştırılmıştır. Elde edilen tüm yapıların yüzey özellikleri incelenmiş ve elektrokimyasal hidrojen üretimindeki katalitik aktiviteleri çeşitli elektrokimyasal yöntemler kullanılarak karşılaştırılmıştır.
