Trapping of atomic hydrogens in cage-shaped silsesquioxanes by electric discharge

Abstract

A simple and safe technique which is based on glow discharge is demonstrated for stable encapsulation of H atoms in cage-shaped silsesquioxanes at room temperature, leading to the encapsulation yield of ca. 10⁻⁴ H atoms per molecule for 10-minute discharging, much faster than the conventional γ-ray irradiation technique.
