AbstractSimultaneous recovery of hydrogen and sulfur resources from acidic gas hydrogen sulfide (H2S), whose content may reach 20-100 % after hydrodesulfurization in oil refineries, is increasingly attractive. Nowadays, the widespread utilization of H2S decomposition technology is mainly restricted by the low hydrogen and sulfur yield, i.e. 20 % at 800 degrees C. In this work, for the first time a novel non-sulfide based LaFexAl12-xO19 hexaaluminate catalysts was used for high (50 %) hydrogen yield at 800 degrees C. At the same time, the active phases and reaction mechanism were confirmed by various characterization techniques. The XRD, Raman, XPS, Mossbauer and XAFS results verified that the Fe species in the hexaaluminate structure, especially octahedral-coordinated Fe3+, served as the main active phases. The reaction routes/mechanism for H2S decomposition were also verified by density functional theory (DFT) method. H2S was firstly adsorbed on the active sites and then completed the decomposition by direct dehydrogenation mechanism. Briefly, current study has minimized the challenges for H2S decomposition at industrial scale. It is anticipated that our findings will offer potential application of H2S decomposing technology.
