Abstract

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.
