Aktif olmayan soy metallerin ilavesi, katalizörün katalitik performansını etkiler. Bu çalışmada, sodyum borohidrit (NaBH4) 'ün 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 katalizi 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 deaktivasyona karşı yüksek tolerans gibi önemli özellikleri içermelidir. En yüksek hidrojen üretim oranı,% 5 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.
