To optimize one-dimensional (1D) TiO 2 nanofibers, tailor-madem ulti-channel TiO 2 nanotubes have been successfully fabricated by electrospinning technology.A fter loading with Ce and V, the CeVTi-tube catalyste xhibited a broad workingt emperature window anda cceptable resistance to H 2 Oa nd SO 2 for elimination of NO x .The corresponding analysisr evealed that the multi-channel structure provided more surfacea dsorbed oxygen species and that the wall of nanotubes anchored activec omponents efficiently, which was beneficial to improve the stability as wella sd ispersion of the active components. Besides, as ynergistice ffect between Ce and Ve asily occurred at the CeVTi-tube catalyst, and its reducibility was significantly improved since the electron transformation between Ce andVwas dramatically enhanced. Consequently,t he tailor-made multi-channel CeVTitube catalyst exhibited satisfied de-NO x efficiencya tt he temperature range of 220-460 8C. It seemed that the multichannel TiO 2 nanotubes hold great potential as an excellent carrierf or SCR catalysts. Figure 1.

Summary This review underlines the importance of the developments in perovskite catalysts for methane combustion from the past up to the present. In this review, after a general and brief introduction to perovskites, the mechanisms of catalytic combustion of methane have been included. Moreover, current studies on perovskites have been summarized including the effects of substitutions, doped perovskites, perovskite preparation methods, and the effect of sulfur presence on perovskite catalysts. Besides, recent studies on perovskite oxides and phenomenon of oxygen (O2) deficiency, porous perovskite oxides, and nanostructured perovskites have been conducted. In addition, partial oxidation of methane (POM) has been reviewed. The loss of active component during the POM reaction can take place in the nickel catalyst, in particular. Since nickel has a lower melting point than noble metals and other active components, such as Co and Fe, in general, to deactivate nickel is easier. Compared with conventional structure, the porous structure with the unique morphology significantly enhances the catalytic activity through a much larger surface area (SA) and greater reactivity of the active sites. Furthermore, the monolithic nanoarrayed perovskite presents very good results in well‐defined faceted catalysts and takes part in porous channel hydrocarbon combustion. This review study is prepared as a guide to cover the profound knowledge of perovskite oxides catalysts, considering the methane combustion reaction mechanisms, and addresses prospective studies in this field for researchers.

“…Studies in recent years revealed that the presence of rare-earth components can effectively regulate the surface acidity and alkalinity, modify the structure of catalytic active centers, improve the oxygen storage/release capacities, and enhance the structural stability and active species dispersion of catalysts. 13,14 As an important component of rare-earth catalytic materials, CeO 2 is a potential substitute for V 2 O 5 due to its high oxygen storage capacity and redox ability when Ce species shi between Ce 4+ and Ce 3+ . 15 28 Furthermore, SiO 2 is widely used as catalyst supports due to their high mechanical strength and excellent thermal stability.…”
