New metal oxide with surface modified by metal-hydride gps. - prepd. by simple hydrogenolysis, useful in organic synthesis or as catalysts or fillers

摘要

M-H gp. surface-modified oxides of formula MxOy, obtd. by hydrogenolysis at 610-1200 [deg]C of an amorphous M-OH gp. surface-modified oxide of formula MxOy, are new. M = hafnium, zirconium, titanium, aluminium or silicon; y = (xXv)/2; v = oxidn. state of M.
