Abstract

Since it can be obtained from renewable sources and has a high heat value, hydrogen is a promising energy source. Chemical hydrides, such as sodium borohydride (NaBH4), are used as hydrogen resources. This is due to their relatively high hydrogen content together with their recyclability. In this study, Ni-B catalysts with Ti addition were prepared for the hydrolysis reaction of NaBH4. In the preparation of Ni-Ti-B catalysts, the chemical reduction technique was used. NiCl2 salt was used as the Ni source, where TiCl3 salt was preferred as the Ti source as the variations of the catalyst activities were determined. With the evaluation of the results, subsequent studies were carried out with the most effective Ti metal salt concentration. The effect of catalysts in different Ti/(Ni+Ti) molar ratios was examined according to the temperature, catalyst loading amount, NaBH4, and NaOH concentrations. The microstructure and elemental analysis of each catalyst were explained by SEM-EDS. After determining the highest performance Ti/(Ni+Ti) molar ratio, the calcination process was performed at different temperatures. For Ni-B catalysts, 5 wt.% NaOH and 5 wt.% NaBH4 were determined as the optimum fuel composition. Moreover, the Ti doped catalysts demonstrated longer durability and hydrogen production rate for hydrolysis of NaBH4.

Abstract [Persian]

از آنجا که هیدروژن را می توان از منابع تجدید پذیر به دست آورد در کنار اینکه دارای مقدار گرمای بالایی است، هیدروژن یک منبع انرژی امیدوار کننده می باشد. از هیدریدهای شیمیایی مانند سدیم بوروهیدرید (NaBH4)، به عنوان منبع هیدروژن استفاده می شود. این به خاطر محتوای هیدروژن نسبتاً زیاد همراه با قابلیت بازیافت آنها می باشد. در این مطالعه، کاتالیزورهای Ni-B با افزودن تیتانیوم برای واکنش هیدرولیز NaBH4آماده شدند. در تهیه کاتالیزورهای Ni-Ti-B، از روش کاهش شیمیایی استفاده شد. نمک NiCl2 به عنوان منبع Ni، در حالیکه از نمک TiCl3 به عنوان منبع تیتانیوم استفاده شد تا تعیین تغییرات فعالیت های کاتالیزور صورت پذیرد. با ارزیابی نتایج، مطالعات بعدی روی موثرترین غلظت نمک فلز تیتانیوم صورت گرفت.  اثر کاتالیزورها در نسبت های مولی مختلف Ti / (Ni + Ti) با توجه به دما ، مقدار کاتالیزور ، غلظت NaBH4 و  NaOH بررسی شده است. ریزساختار ها و تحلیل بنیادی هر کاتالیزور با استفاده از SEM و EDS تفسیر شدند. پس از تعیین بالاترین عملکرد نسبت مولی Ti / (Ni + Ti)، فرآیند تکلیس در دماهای مختلف انجام شد. برای کاتالیزورNi-B ، پنج درصد وزنی NaOH و پنج درصد وزنی NaBH4 به عنوان ترکیب سوخت بهینه تعیین شد. علاوه بر این، کاتالیزورهای با پوشش تیتانیوم نشان دادند که دوام و میزان نرخ تولید هیدروژن بالاتری برای  هیدرولیز NaBH4 دارند.
