“…Much progress has been made in exploring molecular HER transition metal catalysts including cobalt, 9 nickel, 10 palladium 11,12 and iron 13 complexes and heterogeneous metal compounds including selenides, 14 sulfides, 15,16 phosphides [17][18][19][20] and carbides 21,22 for the HER. Metalloporphyrin has been demonstrated as an efficient HER electrocatalyst.…”

“…Chemical hydrogen storage materials have aroused tremendous interest because of their inherent advantages such as high content of hydrogen, no toxicity, low hydrogen releasing temperature, and an easily controllable hydrogen generation process [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Among those materials, potassium borohydride (KBH 4 ) stands out owing to its safe production process, harmless hydrolysis product, low activation energy and enthalpy [ 9 , 10 , 11 , 12 , 13 , 14 ]. Unfortunately, the low hydrogen production rate of KBH 4 self-hydrolysis hinders its large-scale practical application.…”

Recently, developing a cost-effective and high-performance catalyst is regarded as an urgent priority for hydrogen generation technology. In this work, ISOBAM-104 stabilized Co/Fe colloidal catalysts were prepared via a co-reduction method and used for the hydrogen generation from KBH4 hydrolysis. The obtained ISOBAM-104 stabilized Co10Fe90 colloidal catalysts exhibit an outstanding catalytic activity of 37,900 mL-H2 min−1 g-Co−1, which is far higher than that of Fe or Co monometallic nanoparticles (MNPs). The apparent activation energy (Ea) of the as-prepared Co10Fe90 colloidal catalysts is only 14.6 ± 0.7 kJ mol−1, which is much lower than that of previous reported noble metal-based catalysts. The X-ray photoelectron spectroscopy results and density functional theory calculations demonstrate that the electron transfer between Fe and Co atoms is beneficial for the catalytic hydrolysis of KBH4.

“…Denklem 1'de verilen denklemden de görüldüğü üzere üretilen hidrojenin 2 molü metal borhidrürden (MeBH4) geriye kalan 2 molü ise sudan karşılanmaktadır [12,13]. Metal borhidrür çözeltilerinin raf ömrünü uzatmak ve bekletildiğinde açığa çıkan hidrojeni önlemek amacıyla çözelti içerisine sodyum hidroksit (NaOH), potasyum hidroksit (KOH) gibi bazik çözeltiler eklenerek alkali çözeltileri şeklinde depolanabilmektedir [14,15].…”

“…yaptıkları çalışmada, hidrojen üretimi için potasyum borhidrür hidrolizinde kullanmak üzere 5-Amino-2,4diklorofenol-3,5-ditertbutilsalisilaldimin -Pd kompleksi sentezlenmişlerdir. Sentezlenen Palladyum kompleks katalizörünün PBH hidrolizindeki aktivasyon enerjisi 25.194kJ/mol olarak bulunmuştur [14]. Başka bir çalışmada KBH4 hidroliz reaksiyonunda Co-Schiff Base kompleksini katalizör olarak kullanılmıştır.…”

Bu çalışmada nikel, magnetron sputter işlemi ile hazırlanan lam üzerine ince bir film olarak kaplanmış ve alkali potasyum borhidrür hidrolizi için katalizör olarak kullanılmıştır. Çözeltinin sıcaklığı, katalizör miktarı, ağırlıkça % KBH4 oranı, 0,5 M’den HCl’nin ekleme miktarı ve ağırlıkça %NaOH oranı gibi bu katalizörlerin alkali potasyum borhidrür çözeltilerinden hidrojen üretimi üzerindeki performansları araştırıldı. Yanıt yüzey metodojisi ve merkezi kompozit dizaynı kullanarak elde edilen modele göre maksimum HGR değerine 55˚C’de, 0.6 g ince film katalizörün, 2 ml kütlece %13 oranında KBH4 ve kütlece %0.6 oranında NaOH besleme çözeltisine ve 9 ml 0.5 M HCI eklendiği koşullarında gerçekleştirildiğinde 92,8 L/dk. gkat ulaşılmıştır.
