“…Such merit enables them to activate both water and methane more effectively. (Mei et al, 2014) Through the theoretical studies, it was found that the surface-anchored Au 1 atoms with the high valence states can produce the significant covalent metal-support interactions (CMSIs). This demonstrates that isolated Au single atoms instead of Au nanostructures dispersed on the iron oxide nanocrystallites (Au 1 /FeO x ) are more sintering resistant.…”

The real-space resolving of the encapsulated overlayer in the well-known model and industry catalysts, ascribed to the advent of dedicated transmission electron microscopy, enables us to probe novel nano/micro architecture chemistry for better application, revisiting our understanding of this key issue in heterogeneous catalysis. In this review, we summarize the latest progress of real-space observation of SMSI in several well-known systems mainly covered from the metal catalysts (mostly Pt) supported by the TiO2 , CeO2 and Fe3 O4 . As a comparison with the model catalyst Pt/Fe3 O4 , the industrial catalyst Cu/ZnO is also listed, followed with the suggested ongoing directions in the field.

“…Generally, the catalytic activity of noble metals is significantly different in various cases. In previous studies, an activity order of Pd > Ir > Pt~Rh > Ru > Ni was given in steam reforming of methane [177]. However, Dagle et al [169] reported that Ir and Rh showed better performance than Ni, Ru, Pt and Pd in terms of activity and stability in steam reforming of methane containing benzene and naphthalene.…”

“…Noble metals (Pt, Rh, Ru, and Ir) supported on various oxide supports that have been extensively studied in the past for SRM can overcome these shortcomings of Ni-based systems. A series of noble metal catalysts supported on MgAl 2 O 4 and Al 2 O 3 using incipient wetness impregnation method were evaluated for SRM [86]. Exceptionally high metal dispersions were recorded for the case of Ir and Rh (100% and 50%, respectively) with particle sizes less than 2 nm, which was reflected in their superior activity and stability (five times higher than Ni/MgAl 2 O 4 ).…”

Abstract:Over the past few years, great attention is paid to syngas production processes from different resources especially from abundant sources, such as methane. This review of the literature is intended for syngas production from methane through the dry reforming (DRM) and the steam reforming of methane (SRM). The catalyst development for DRM and SRM represents the key factor to realize a commercial application through the utilization of more efficient catalytic systems. Due to the enormous amount of published literature in this field, the current work is mainly dedicated to the most recent achievements in the metal-oxide catalyst development for DRM and SRM in the past five years. Ni-based supported catalysts are considered the most widely used catalysts for DRM and SRM, which are commercially available; hence, this review has focused on the recent advancements achieved in Ni catalysts with special focus on the various attempts to address the catalyst deactivation challenge in both DRM and SRM applications. Furthermore, other catalytic systems, including Co-based catalysts, noble metals (Pt, Rh, Ru, and Ir), and bimetallic systems have been included in this literature review to understand the observed improvements in the catalytic activities and coke suppression property of these catalysts.
