纸结构催化剂(paper-structured catalyst, PSC)是一种柔性的平面催化剂,可以在SOFC的阳极上堆叠,在SOFC的工作温度下对碳氢燃料的重整表现出优异的催化活性。虽然我们的最终目标是通过应用PSC实现以沼气为燃料的直接内重整(DIR) SOFCs,但为了将PSC实际应用于以沼气为燃料的DIR-SOFCs,必须提高PSC对沼气中硫杂质(H2S)的耐受性。本研究采用造纸工艺制备了一种层状双氢氧化物(Mg/ al水滑石,记为HT)分散在其中的无机纤维网络,并通过浸渍工艺将Ni加载到该纸基体中。这种负载ni的ht分散PSC对H2S的耐受性比不含ht的PSC高得多。
A paper-structured catalyst (PSC) is a flexible planar catalyst that can be stacked on the anode of SOFCs and exhibits excellent catalytic activity for the reforming of hydrocarbon fuels at the operating temperature of the SOFC. Although our final goal is the realization of direct internal reforming (DIR) SOFCs fueled by biogas by applying a PSC, the tolerance of PSCs to sulfur impurities in biogas (H2S) must be improved for the practical application of PSCs to DIR-SOFCs operated by biogas. In this study, an inorganic fiber network in which a layered double hydroxide (Mg/Al-hydrotalcite denoted as HT) is dispersed was prepared by a paper-making process, and Ni was then loaded in this paper matrix via an impregnation process. This Ni-loaded HT-dispersed PSC exhibited considerably higher tolerance to H2S than that of HT-free PSC.
