      abstract     = {Low-temperature NOx storage materials for lean NOx traps
                      based on nanocomposites containing perovskite-type oxides of
                      La0.5Sr0.5Fe1-xMxO3-δ (M = Ti, Nb or Zr; x = 0.25 or 0.5)
                      are prepared in a highly porous alumina with different
                      loadings of 15−25 wt. $\%.$ The resulting storage
                      materials are characterised by X-ray diffraction, BET and
                      transmission electron microscopy with coupled ASTAR system
                      for crystallite phase mapping. For all nanocomposites high
                      surface areas around 100 m²/g are found. With perovskite
                      loadings of 20 wt. $\%$ the platinised composites reveal NOx
                      storage capacities between 120–164 μmol/g below 300 °C
                      with a performance ranking of Zr > Ti > Nb. After
                      hydrothermal ageing at 750 °C only for the Nb and Zr
                      containing composites a decrease of the NSC up to 20 $\%$
                      can be observed. The NSC of the LSFT system can be improved
                      by decreasing the perovskite loading to 15 wt. $\%.$},
