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 H2S 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 LaxFeyOz/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 N2 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
