Aktif Co-Ti (II) -B alaşım katalizörlerinin hidrojen üretiminde NaBH4 hidroliz reaksiyonu ve çevresel etkiler için kinetik özelliklerin analizi

Aktif olmayan soy metallerin ilavesi, katalizörün katalitik performansını etkiler. Bu çalışmada, sodyum borohidrit (NaBH4) 'in katalitik hidroliziyle hidrojen üretimi için TiCl2 metal tuzundan yeni ve verimli bir üçlü Kobalt-Titanyum (II) -Borid (Co-Ti(II)-B) katalizörleri hazırlanmıştır. Co-Ti(II)-B katalizörü yardımıyla, hidrojen üretim oranı, farklı titanyum konsantrasyonu, çözelti sıcaklığı, NaBH4 konsantrasyonu ve NaOH (baz dengeleyici) konsantrasyonunun bir fonksiyonu olarak ölçülmüştür. Katalizörün aktivitesi, termodinamik bakış açılarından analiz edilmiş ve Co-B katalizörü ile karşılaştırılmıştır. Yüksek katalitik verimliliğe ek olarak, katalizör ciddi koşullarda yüksek kararlılık ve aktivasyon kaybına karşı yüksek tolerans gibi önemli özellikleri içermelidir. En yüksek hidrojen üretim oranı, %5 ağ. Ti/(Ti + Co) molar oranı ile elde edilmiş ve bu katalizör için, optimum yakıt konsantrasyonu, ağırlıkça %7,5 NaOH ile %7,5 NaBH4 olarak tanımlanmıştır.
