The reaction mechanism of the reverse water–gas shift (RWGS) was investigated using two commercial gold-based catalysts supported on Al2O3 and TiO2. surface species formed during mechanisms were elucidated by transient steady-state operando DRIFTS studies. It revealed that RWGS over Au/Al2O3 proceeds through formation formate intermediates are reduced to CO. In case Au/TiO2 catalyst, goes a redox with suggested hydroxycarbonyl intermediates, which further decompose CO water. Ti3+ species,...
Carbon formation and sintering remain the main culprits regarding catalyst deactivation in dry bi-reforming of methane reactions (DRM BRM, respectively). Nickel based catalysts (10 wt.%) supported on alumina (Al2O3) have shown no exception this study, but can be improved by addition tin ceria. The effect two different Sn loadings base been examined for DRM reaction over 20 h, before selecting most appropriate Sn/Ni ratio promoting with wt.% CeO2. This then underwent activity measurements a...
The energy crisis caused by the incessant growth in global demand joint to its associated greenhouse emissions motivates urgent need control and mitigate atmospheric CO2 levels. Leveraging as carbon pool produce value-added products represents a cornerstone of circular economy. Among utilization strategies, electrochemical reduction conversion fuels chemicals is booming due versatility end-product flexibility. Herein most studies focused on C1 although C2 C2+ compounds are chemically...
Beyond its role as an energy vector, a growing number of natural hydrogen sources and reservoirs are being discovered all over the globe, which could represent clean source. Although amounts in uncertain, they be vast, help decarbonize energy-intensive economic sectors facilitate transition. Natural is mainly produced through geochemical process known serpentinization, involves reaction water with low-silica, ferrous minerals. In favorable locations, can become trapped by impermeable rocks...
A series of Ce1−xEuxO2−x/2 mixed oxides was synthesized by coprecipitation. The solids were characterized means XRF, SBET, XRD, UV−vis, and Raman techniques, their catalytic activities toward CO oxidation tested. solid solution, with CeO2 F-type structure, is formed for europium contents (measured as Eu2O3 XRF) ≤20% wt. For higher contents, the solution not formed, but a physical mixture detected. existence oxygen vacancies in between 3 17% wt demonstrated presence bands at 532 1275 cm−1...
