Bu çalışmada nikel, magnetron saçtırma işlemi ile lam üzerine ince bir film olarak kaplanmış ve alkali potasyum borhidrür hidrolizinde katalizör olarak kullanılmıştır. Ayrıca ortam sıcaklığı, katalizör miktarı, % KBH4 oranı, HCl hacmi ve % NaOH oranı gibi parametrelerin potasyum borhidrür çözeltisinin katalitik hidrolizinde hidrojen üretimi hızına olan etkileri de yanıt yüzey metodu ile ayrıntılı olarak incelenmiştir. Proses optimizasyonu merkezi kompozit dizaynı kullanılarak yapılmış ve parametrelerin etkinliği varyans analizi ile belirlenmiştir. Oluşturulan model sonucunda, maksimum HGR değeri için optimum parametreler; ortam sıcaklığı 55 ˚C; %13 oranında KBH4; %0.6 oranında NaOH; 9 mL 0.5 M HCI olarak belirlenmiştir. Maksimum hidrojen üretim hızı 92.8 L/dk. g olarak hesaplanmıştır.

In this study, nickel was coated as a thin film on the slide by magnetron sputtering and used as a catalyst for alkali potassium borohydride hydrolysis. The effects of parameters such as ambient temperature, catalyst amount, wt% KBH4 ratio, volume of HCl and wt% NaOH ratio rate on the hydrogen production rate in the catalytic hydrolysis of potassium borohydride solution were investigated in detail by response surface method. Process optimization was done using central composite design and the efficiency of the parameters was determined by analysis of variance. As a result of the model created, the optimum parameters for the maximum HGR value; ambient temperature 55 ˚C; 13% KBH4; 0.6% NaOH; Determined as 9 mL of 0.5 M HCl. The maximum hydrogen generation rate was calculated as 92.8 L/min g.
