Investigation into Hydrolysis of Alkaline Sodium Borohydride Solution using Attapulgite Clay-Supported Co-B-Ce Catalyst

摘要：

Hydrolysis of sodium borohydride is regarded as a promising technology to produce pure hydrogen in portable fuel cell fields. In this paper, Ce is examined to be a better co-catalyst than Ni and Fe for the attapulgite clay (AT)-supported cobalt-boride (Co-B) catalyst. Factors, such as solution temperature, NaBH4 concentration and NaOH concentration on performance of these catalysts in hydrolysis of sodium borohydride are investigated. Furthermore, characteristics of these AT-supported catalysts are studied using SEM and XRD. Activation energy of hydrogen generation using such catalysts is estimated to be 37.02 kJ/mol.
