Aimed at the integral catalyst required for the hydrogen production of NaBH4 hydrolysis,the chemical composition,thermal stability and microstructure of fibrous sepiolite before and after encapsulation were analyzed,then it was compounded,blended,pressed and sintered with industrial cinder powder to obtain cobalt-based oxide-loaded fibrous sepiolite (Co3O4@Sepiolite)-cinder porous ceramics.The microstructure and water absorption of the ceramic blanks after sintering at high temperature were studied,and the catalytic hydrogen production performance of NaBH4 was further investigated.The results showed that the sepiolite still exhibited a fibrous structure after encapsulation.Under the same sintering process,Co3O4@sepiolite-cinder porous ceramics showed higher hydrogen production rate and strong structural stability during the catalytic process compared with pure cinder porous ceramics,which was attributed to the structural coupling effect generated in the sintering process.
