Abstract

One of the major problems of today‟s world is in its heavy dependency on fossil fuels for energy requirements. The increase in energy requirements causes environmental problems and leads to an increase in energy costs. It has already been obvious that the solution to these problems is to use of sustainable energy resources. Since hydrogen, the most abundant element is the cleanest and ideal fuel, has been considered as the fuel of the future. The simplest way of hydrogen production is the electrolysis of water. The major problem in the electrolysis of water for the hydrogen evolution is the increase in costs due to overvoltage of the electrochemical system. In this study, first the surface of the aluminium electrode as a cheap material, coated with polyanilin (PAni)-Chitosan composite film, then the gold (Au) nanoparticles electrodeposited on this composite surface which show high catalytic activity toward hydrogen production. The surface properties of the all obtained structures are investigated and the catalytic activities of the structures are compared with various electrochemical techniques for the electrocatalytic hydrogen production

Özet

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
