A review on perovskite catalysts for reforming of methane to hydrogen production

Hydrogen is regarded as one of the promising sustainable energy carriers for human society. Methane reforming is crucial to hydrogen energy industry since it is the main route to obtain hydrogen. Ni-based catalyst has been extensively explored because of its low price and good catalytic activity. However, it suffers from fast deactivation caused by carbon deposition. Perovskite with its unique structure, has been a popular candidate for catalyst precursors and lots of related literature is published. In this review, the application of perovskite catalysts for methane reforming is discussed in details. Typical LaNiO3 has shown its superb carbon-resistance due to the strong interaction between La2O3 and CO2. The substitution of A and B sites could modify the structure and improve the catalytic performance further. Recent advances on this topic are presented as well. It is beneficial to increase the surface area by preparation supported and porous perovskite. Finally, a summary with future outlooks is raised for the future development of perovskite catalysts.
