Fast hydrogen generation from NaBH4 hydrolysis catalyzed by carbon aerogels supported cobalt nanoparticles

Hydrogen generation from alkaline NaBH 4 solution using electroless-deposited Co–W–P supported on γ-Al 2 O 3

“…The results indicate that OH À anions play dual roles during the hydrolysis of NaBH 4 . These findings are consistent with the reports on CoeB [4,17] or Co [11,41] catalysts. However, these results are different from those investigations on CoeMoePdeB [8], Ni-Ru [42] or Ru [43] catalysts.…”

“…It is observed that the hydrogen generation rate drastically increases with increase in NaBH 4 concentration and subsequently decreases with further increase in NaBH 4 concentration. Many researchers [11,41] had found that the hydrogen generation rate decreases with higher NaBH 4 concentration. It is because that BH 4 -can be in good adsorption and desorption in the surface of catalysts at low concentration of sodium borohydride.…”

Bimetallic Co–Ni based complex catalyst for hydrogen production by catalytic hydrolysis of sodium borohydride with an alternative approach

“…Several studies on the hydrolysis of NaBH 4 to hydrogen using most transition metals have been reported in literature. For instance, non-noble metal catalysts such as Co supported catalyst [3e5], CoeFe catalyst [6], Ni based catalyst [7], CoeNi catalyst [8], NieB catalyst [9], NieCoB catalyst [10], CueCo catalyst [11,12], CoeCueB catalyst [13], CoeWeB [14] catalyst, noble metal catalysts like Ruthenium supported catalyst [1,15e17], Pd complex catalyst [18], Ce 0.05 eNieWeB catalyst [23], Pd, PteRu, PtePd alloys [20e22], CoeB nanocatalyst [23], CoeMoeB [24], carbon aerogels supported cobalt nanoparticles [25], CoeLaeZreB nano particles [26] etc.…”

A Recycling Hydrogen Supply System of NaBH4 Based on a Facile Regeneration Process: A Review

“…It has relatively high hydrogen capacity (10.8 wt %) [46][47][48] and releases hydrogen with high purity at relatively low operational temperature with a controllable process [24,49,50]. Many studies have been focused on the hydrolysis property improvements [51][52][53][54]. Unfortunately, a no-go recommendation on NaBH 4 hydrolysis for onboard applications was given by the US Department of Energy (DOE) [55].…”
