Yüksek Aktiviteye Sahip CNT Destekli Pd-Zn Katalizörünün Formik Asit Elektrooksitlenme Aktivitesinin İncelenmesi
Öz
Dünyada artan
enerji ihtiyacına ek olarak petrol rezervlerinin zamanla azalması bilim dünyasını
alternatif enerji kaynakları bulmaya ve bu alanda çalışmalar yapmaya itmiştir.
Yakıt hücreleri de birçok alanda kullanıma elverişli olduğundan, araştırmacılar
arasında çok popülerdir. Bu çalışmada karbon nanotüp destekli Pd (Pd/CNT) ve
PdZn (PdZn/CNT) katalizörleri NaBH4 indirgeme yöntemiyle
sentezlenmiştir ve bu katalizörlerin formik asit elektrooksidasyonu için
performansları ve optimum operasyon koşulları araştırılmıştır. Sentezlenen
katalizörler X-ışını kırınım yöntemi (XRD) ve Endüktif olarak eşleşmiş
plazma-kütle spektrometresi (ICP‐MS) ile
karakterize edilmiştir. Katalizörlerin performansı ise dönüşümlü voltametri
(CV), kronoampermetri (CA) ve elektrokimyasal empedans spektroskobisi (EIS)
yöntemleri kullanılarak ölçülmüştür. PdZn/CNT katalizörü 402.1 mA/mg Pd ile
Pd/CNT’ye göre çok daha yüksek kütlesel aktivite göstermiştir.
