摘要

Herein, a nickel foam (NF) (Φ27 mm × 2 mm) was employed as a structured carrier. First, porous nitrogen-doped carbon (N–C) was synthesized in situ on this NF via a hydrothermal method followed by activation treatment. Subsequently, Pt particles were deposited on the N–C coated NF by reducing Pt in the high-valence state using H2. Finally, the superhydrophobic Pt/N–C/NF catalyst was fabricated via hydrophobic modification using 1H, 1H, 2H, 2H-heptadecafluorodecyltrimethoxysilane, achieving a contact angle of 162°. Results showed that the average particle size of Pt was only 1.41 nm and that the zero-valence Pt content was 65%. These outstanding properties endowed Pt/N–C/NF with excellent catalytic activity in water–hydrogen exchange reactions, achieving a total volumetric mass transfer coefficient of 7.60 × 10−2 s−1.
