    An efficient TiO2-supported ruthenium (Ru/TiO2) catalyst for electrochemical hydrogen generation from aqueous potassium borohydride
    (S.C. Virtual Company of Phisics S.R.L, 2020) Keskin, M.S.; Ağirtaş, M.S.; Şahın, Ö.; Horoz, S.
    In this study, a TiO2-supported ruthenium catalyst (denoted as Ru/TiO2) was facilely synthesized by chemical reduction method without the use of any chemical reducing reagents. Using a 2 wt.% KBH4 + 1 wt.% KOH solution, hydrogen generation rate was as high as 137423.9 mL* min-1 g-1at 30 0C, and apparent activation energy was calculated as 55.48 kJ*mol-1. Compared with similar Ru-based catalysts reported in literature, the Ru/TiO2 catalyst synthesized by chemical reduction method in this study indicates higher catalytic activity and lower apparent activation energy. © 2020, S.C.
