To enhance the catalytic performance of sodium borohydride hydrolysis, a boron oxide-coated Co–Pt/boron nitride (BN) nanocomposite material has been developed, leveraging the oxidative support–metal strong interaction.

Indications for hydrofluoric acid (HF) scavenging by TMSP could be found in the gas phase as well as on the electrode surfaces; however, it is observed that the use of TMSP leads to the production of HF, which it eventually scavenges. The investigation of the interphase formation shows that the decomposition products of TMSP are integrated into the interphases of both electrodes. This is accompanied by the formation of trimethylsilane as a decomposition product in the gas phase. TMSP also promotes the two-electron reduction of ethylene carbonate (EC), which is deduced both from an increased amount of ethene in the gas phase and from Li<sub>2</sub>CO<sub>3</sub> on the electrode surface.
