摘要
Ru and Co are highly dispersed on the surface of TiO2 nanopa rticles with an easy coprecipitation method to fabricate a novel Ru-based catalyst(Ru/Co-TiO2).The fabricated Ru/Co-TiO2 catalyst exhibits superior catalytic performance for promoting NaBH4 hydrolysis in alkaline medium,showing an impressive hydrogen generation rate per gram Ru as high as 172 L min-1 gRu-1 which is better than most of recently reported Ru-based catalysts.In addition,the fabricated Ru/Co-TiO2 catalyst also shows excellent du rability in cycle use,with only 2.9% activity loss after being used for 5 cycles.These advantages make the developed Ru/Co-TiO2 catalyst a potential choice for promoting hydrogen generation from NaBH4 hydrolysis.
