Abstract

본 발명은 수소분리용 무기재료막의 제조방법에 관한 것이다. 좀더 구체적으로, 본 발명은 졸겔법을 사용하여 알루미나 지지체의 중간층에 알루미나 지지막을 코팅하고 알루미나 지지막을 기공에 팔라듐을 침투증착시켜 높은 투과도와 우수한 수소 분리선택도를 지닌 수소분리용 무기재료막을 제조하는 방법에 관한 것이다. 본 발명의 무기재료막은 졸겔법을 사용하여 알루미나 졸에 팔라듐 전구체를 균일하게 분산시키고 내부를 진공상태로 유지한 알루미나 지지체에 침적코팅시켜 지지체의 중간층에 알루미나 지지막층을 형성하는 공정; 전기한 공정에서 수득한 알루미나 지지막을 팔라듐 전구체의 침투혼합액에 담가 지지체의 내부를 진공으로 유지하고 알루미나 지지막층의 기공에 팔라듐 전구체를 침투시켜 2 내지 4시간 동안 건조시키고 170내지 190℃까지 승온시켜 지지막층의 기공표면에 팔라듐을 증착시키는 공정; 및 전기 공정에서 수득한 지지막층의 기표면에 팔라듐이 증착된 알루미나 지지체의 내부를 진공으로 유지하면서 290 내지 310℃에서 열처리하는 공정을 포함한다.
