For the first time, solid acid sulphated-zirconia (ZrO(2)-SO(4)(2-), SZ) has been used as support of metal catalysts for hydrogen generation from catalytic hydrolysis of alkaline solution of sodium tetrahydroborate NaBH(4). SZ was prepared according to an optimised one-step sol-gel method. Pt- or Ru-promoted SZs (Pt-SZ or Ru-SZ) were then got by wet impregnation. On the one hand, Pt-SZ was rather inefficient. On the other hand, Ru-SZ showed very promising hydrogen generation abilities with a hydrogen generation rate of similar to 10 L(H(2)) min(-1) g(-1) of Ru. This performance is one of the best ones published in the literature.
