Hydrogen Storage Properties of Ultrasound-Assisted Synthesized Pt Nanosheets
The synthesis of platinum nanoparticles was conducted in this research via the sol–gel method in the presence of ultrasound as a dispersing and reaction device in ascorbic acid. The synthon for Pt was the novel complex of platinum with 3,4,5-trimethoxybenzoic acid and [Pt(TMB)2]. The Pt nanoparticle was characterized using XRD and TEM; the results demonstrate the formation of a sheet-like structure of pure Pt NPs with a thickness of 20 nm. The prepared complex (synthon) was synthesized via a one-step method in the presence of an alkali medium (NaOH), and the product was characterized using FTIR, 1H-NMR, and mass spectra. The prepared complex and the prepared nanoparticles were used as gas-capturing material. The study was conducted in the pressure range of 0–100 bar at 173 K, and then the thermodynamic properties were calculated at different temperatures (77–273 K). The results demonstrate that the enthalpy was equal to −53.350615 KJ/mol H2 (while the entropy was −338.881 J/mol H2).
