Representative electron microscopy images of calcined and spent catalysts. a, b Pd/H-MOR, c, d Pd/Na-MOR, e, f Pd/H-MOR-BE. Spent catalysts were aged in 1 vol% CH4, 4 vol% O2, 5 vol% H2O, N2 bal. at 415 °C for 16 h. STEM and secondary electron (SE) images of g, h Pd/Na-MOR and i, j Pd/H-MOR after 90 h and 65 h on stream, respectively, continuous with short pulse regeneration. Scale bar: 20 nm (a–h) and 50 nm (i, j)
