Catalytic dehydration of 2-propanol over nickel phosphide immobilized on natural bentonite

This study investigated the fabrication of nickel phosphide immobilized on natural bentonite (NiP/bentonite) as a low-cost catalyst with different metal loadings (mEq/g) to produce diisopropyl ether (DIPE) as a potential gasoline additive. The catalysts were prepared using a simple wet-impregnation...
