Ti3C2X2 (X = OH, F) (a transition metal carbide that resembles graphene and is loaded with Ru) had an HGR of 59.04x10 3 mL/min•g . At room temperature, Ru(0) nanoclusters displayed a maximum HGR of 96.8x10 3 mL/min•g . Additionally, it may be supported by reduced graphene oxide (rGO) via polyvinylpyrrolidone (PVP) stabilization and electrostatic self-assembly . By employing an aqueous ammonia borane solution to reduce Ru 3+ , chitin-supported Ru was created . The HGR for NaBH4 hydrolysis at 30 °C is as high as 55.290x10 3 mL/min•g with an activation energy of 0.07 wt.% Ru. Noble-based catalysts such as Ru-Ni exhibit good durability and excellent recyclaibility over 300 cycles .
