Synergistic phase and crystallinity engineering in cubic RuSe2 catalysts towards efficient hydrogen evolution reaction

Wei Zhan et al.

Summary: In this study, cubic RuSe2 electrocatalysts with varying 1T phase ratios and crystallinities were developed using a fast and efficient synthesis method. The RuSe2-500 catalyst exhibited outstanding performance with a small overpotential and Tafel slope, attributed to its high crystallinity and appropriate 1T phase content. Additionally, RuSe2-500 showed the lowest charge transfer resistance due to its abundant active centers and excellent conductivity from the 1T phase, benefiting the hydrogen evolution reaction kinetics and catalytic performance.

Ru/graphene hybrid film catalyst for NaBH4 hydrolysis reaction

Daba Deme Megersa et al.

Summary: This study proposes a thermal release tape-supported Ru on graphene film (Ru/G/TRT) as a catalyst for the dehydrogenation of sodium borohydride (NaBH4). A Ru film deposited on sapphire was used to synthesize graphene, and the successful synthesis of graphene was confirmed by Raman spectroscopy and scanning electron microscopy. The catalytic performance of the Ru/G/TRT structure was found to be significantly improved compared to the etched Ru/G structure, with stability maintained after repeated use.
