In this work, naturally available clay, halloysite (Hal) nanotube was modified systematically with various types and number of amine groups containing modifying agents and used as catalyst in the methanolysis of sodium borohydride (NaBH4) for hydrogen (H2) production. The modifying agents such as ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), and tris(2-aminoethyl)amine...
Here, for the first time a natural clay, halloysite nanotubes (HNTs) was used as catalyst in H2 generation from methanolysis of sodium borohydride (NaBH4). The natural HTNs were modified with (3-aminopropyl)triethoxysilane (APTES) and then threated with HCl to obtain mod-HNTs (HNTs-NH2·HCl) as natural catalysts. The catalytic activity of mod-HNTs was found to be comparable for the very well-known...
