      abstract     = {Coupling of two oxygen-involved reactions at the opposite
                      sides of an oxygen transport membrane (OTM) has demonstrated
                      great potential for process intensification. However, the
                      current cobalt- or iron-containing OTMs suffer from poor
                      reduction tolerance, which are incompetent for membrane
                      reactor working in low oxygen partial pressure (pO2). Here,
                      we report for the first time a both Co- and Fe-free
                      SrMg0.15Zr0.05Ti0.8O3−δ (SMZ-Ti) membrane that exhibits
                      both superior reduction tolerance for 100 h in 20 $vol.\%$
                      H2/Ar and environment-induced mixed conductivity due to the
                      modest reduction of Ti4+ to Ti3+ in low pO2. We further
                      demonstrate that SMZ-Ti is ideally suited for membrane
                      reactor where water splitting is coupled with methane
                      reforming at the opposite sides to simultaneously obtain
                      hydrogen and synthesis gas. These results extend the scope
                      of mixed conducting materials to include titanates and open
                      up new avenues for the design of chemically stable membrane
                      materials for high-performance membrane reactors.},
