Abstract

The present work includes the synthesis of aluminum oxide (Al2O3), multi-walled carbon nanotube (MWCNT), and Eupergit CM-supported Co-based nanoparticles (Co–Fe–B and Co–Mn–B), and the investigation of their hydrolytic efficiency in H2 generation from the catalytic hydrolysis of ammonia borane (NH3BH3). Among the supported catalysts, Co–Fe–B/Eupergit CM exhibited the highest H2 generation rate as 4539 mLmin−1gcatalyst−1 compared to Co–Fe–B/Al2O3 and Co–Fe–B/MWCNT, which exhibited 4373 mLmin−1gcatalyst−1 and 3294 mLmin−1gcatalyst−1, respectively. When Co–Mn–B/ Eupergit CM was used instead of Co–Fe–B/ Eupergit CM, a significant increase in the highest HGR (19.422 mLmin−1gcatalyst−1) was found. Moreover, turnover frequency (TOF) value was calculated as 318 h−1 and 646 h−1 for Co–Fe–B/Eupergit CM and Co–Mn–B/Eupergit CM, respectively.
