Mixed ionic-electronic conducting (MIEC) membrane reactors are a promising technology for H2 production through coupling of H2O splitting with CO2 capture. To meet the high reliability requirement to the membrane reactors for an industrial process, it is necessary to develop membrane materials with high mechanical strength and high chemical stability. In this work, a series of x wt % YSZ-(98 – x) wt % La0.7Sr0.27Cr0.4Fe0.6O3−δ-2 wt % CuO (x = 40, 50, 60 and 70; denoted as YL4, YL5, YL6, and YL7, respectively) dual-phase membranes were prepared for coupling water splitting with CO2 capture. The results demonstrate that the mechanical strength of the dual-phase membrane increases significantly with the addition of YSZ and is much higher than that of the single perovskite material LSCF. The conductivity and H2 production rates increase in the order of YL4 > YL5 > YL6 > YL7. The structure stability of the perovskite phase in dual-phase membranes increases with the content of YSZ phase under the operation condition of membrane reactors. The YL6-based membrane reactor was operated steadily for 290 h, indicating that it is a promising membrane material for H2 production by coupling water splitting with CO2 capture.

基于 YSZ 的双相膜反应器，通过耦合水分解和 CO2 捕获来生产氢气
混合离子电子传导(MIEC)膜反应器是一种通过H 2 O分解与CO 2捕获耦合生产H 2的有前途的技术。为了满足工业过程对膜反应器的高可靠性要求，需要开发具有高机械强度和高化学稳定性的膜材料。在这项工作中，一系列x wt % YSZ-(98 – x ) wt % La 0.7 Sr 0.27 Cr 0.4 Fe 0.6 O 3−δ -2 wt % CuO ( x = 40, 50, 60 和 70; 表示为 YL4 、YL5、YL6 和YL7）双相膜被制备用于耦合水分解与CO 2捕获。结果表明，双相膜的机械强度随着YSZ的添加而显着增加，并且远高于单一钙钛矿材料LSCF的机械强度。电导率和H 2生产率按照YL4> YL5> YL6> YL7的顺序增加。在膜反应器的运行条件下，双相膜中钙钛矿相的结构稳定性随着YSZ相含量的增加而增加。 YL6基膜反应器稳定运行了290 h，表明它是一种有前景的通过耦合水分解和CO 2捕获来生产H 2的膜材料。
