Highly ordered nanorod arrays 9Mn1Ce metal oxides (MOs) were prepared by negative replication of SBA‐15 hard template and were used directly for hot coal gas desulfurization at 600°C. The results indicated that 9Mn1CeMOs sorbent presented a superior desulfurization activity and small resistance of H 2 S diffusion compared with 9Mn1Ce mixed oxides. The breakthrough sulfur capacity (19.03 g‐S/100 sorbent) was significantly higher than that (7.94 g‐S/100 sorbent) over La x Fe y O z /MCM‐41 due to highly ordered nano‐rod array structure. The five successive sulfidation/regeneration cycles verified that 9Mn1CeMOs exhibited highly durable regeneration ability. The morphology and structure of the 9Mn1CeMOs were characterized by scanning electron microscopy, high‐resolution transmission electron microscope, X‐ray diffraction, and N 2 adsorption, it revealed that parallel nanorod arrays formed with a diameter of 6–7 nm and the nanobridges between the nanorods played a crucial role for the stability of 9Mn1CeMOs. © 2014 American Institute of Chemical Engineers Environ Prog, 33: 1266–1273, 2014
