Ru-Fe nanoparticles (Ru-Fe@PVP) stabilized with poly(N-vinyl-2-pyrrolidone) (PVP) were synthesized by a widely used alcohol reduction technique. The synthesized nanoparticles were characterized by SEM, SEM/EDX, UV/Vis techniques. The prepared nanoparticles were used as a catalyst in the production of hydrogen from the hydrolysis reaction of methylamine-borane, an important boron-nitrogen (B-N) derivative that stores hydrogen in solid state. Bimetallic nanoparticles, which were calculated as TOF (38.4 1/min) and activation energy (87.7 kJ/mol), were evaluated as an efficient catalytic system with these properties. As a result of the investigation of the effects of catalyst and substrate concentrations on the catalytic reaction, it was determined that the rate expression of the reaction progressed from 0.5 order according to the catalyst concentration and 1.7 order according to the substrate concentration.
Poli(N-vinil-2-pirolidon) (PVP) ile kararlaştırılmış Ru-Fe nanoparçacıkları (RuFe@PVP) yaygın olarak kullanılan bir alkol indirgeme tekniği ile sentezlendi. Sentezlenen nanoparçacıklar SEM, SEM/EDX, UV/Vis teknikleriyle karakterize edildi. Hazırlanan nanoparçacıklar katı halde hidrojen depolayan önemli bir bor-azot (B-N) türevi olan metilamin-boranın hidroliz tepkimesinden hidrojen üretiminde katalizör olarak kullanıldı. TOF değeri (38.4 1/min) ve aktivasyon enerjisi (87.7 kJ/mol) olarak hesaplanan iki metalli nanoparçacıklar bu özellikleri ile verimli bir katalitik sistem olarak değerlendirildi. Katalizör ve substrat derişimlerinin katalitik tepkime üzerindeki etkilerinin araştırılması sonucu tepkimenin hız ifadesinin; katalizör derişimine göre 0.5 mertebeden, substrat derişimine göre ise 1.7 mertebeden ilerlediği tespit edildi.
