Electrospun nickel nanoparticles@poly(vinylidene fluoride-hexafluoropropylene) nanofibers as effective and reusable catalyst for H2 generation from sodium borohydride

Nickel nanoparticles (Ni NPs) supported on Poly(vinylidene fluoride-co-hexafluoropropylene) nanofibers (PVDF-HFP NFs) were successfully synthesized through electrospinning and in-situ reduction of Ni2+ salts into the surface PVDF-HFP NFs to form metallic Ni [email protected] NFs. Different percentages nickel acetate tetrahydrate (NiAc) (10 %, 20 30 40 % wt.) based PVDF-HFP. The formation tiny NPs @PVDF-HFP membrane was demonstrated using standard physiochemical techniques. Nanofibers membranes have good catalytic activity in H2 production from sodium borohydride (NaBH4). sample composed %wt showed highest compared other formulations. Whereas 103 mL H2, hydrolysis 1.34 mmol NaBH4, produced wt% NiAc 68 mL, 81 93 for 10 wt%, NiAc, respectively, 60 min at 25 °C. hydrogen generation has been enhanced with an increase amount reaction temperature. latter results a low activation energy (23.52 kJ mol−1). kinetics study revealed that pseudo-first-order concentration catalyst amount. Furthermore, exhibits satisfactory stability process ten cycles. Because its easy recyclability, introduced wide range potential applications hydrolysis.
