Silika destekli Ni (II)-Schiff Bazı kompleksinin hazırlanması amacıyla, daha önceki çalışmamızda sentezlenen [1] Ni(II)-Schiff Bazı Kompleksi, SiO2 üzerine tutturularak SiO2 destekli Ni(II)-Schiff Bazı kompleksi elde edildi.  Hazırlanan bu SiO2 destekli kompleks, katalitik aktivitesine bakılmak üzere hidrojen üretim için NaBH4’ün hidroliz reaksiyonunda katalizör olarak kullanıldı. Hazırlanan bu katalizörün yapısı FT-IR, SEM, XRD, BET analizi gibi spektroskopik yöntemlerle aydınlatıldı.  SiO2 destekli Ni(II)-Schiff Bazı kompleksinin katalizör olarak kullanıldığı NaBH4’ün hidroliz reaksiyonu; NaOH ve NaBH4 konsantrasyonuna, katalizör miktarına, SiO2 destekli Ni(II)-Schiff Bazı kompleks katalizörünün içerisinde bulunan Ni (II)-Schiff Bazı kompleksinin yüzdesine ve sıcaklığa bağlı olarak incelendi.  NaBH4’ün hidroliz reaksiyonuna ait maksimum reaksiyon hızı (R0)  13005 mL H2 g-1 kat. dk-1, reaksiyonun aktivasyon enerjisi (Ea) ise 16,633 kJ/mol olarak, reaksiyon hız mertebesi n ise 0,3 olarak hesaplanmıştır.
