Ammonia is a promising COx-free hydrogen (H2) carrier because of its high volumetric H2 density. However, developing highly active/stable ammonia decomposition catalysts for production remains challenging. In this study, the role ceria (CeO2) as promoter Ru-based was investigated. Ru/Cex/MgAl(y00) were prepared by incipient wetness impregnation (IWP) and deposition–precipitation (DP) methods. The surface oxygen vacancy (OV) concentration controlled Ce loading calcination temperature. By...
E-fuel production, which is achieved using atmospheric or biogenic CO2 and green H2, shows promise for reducing levels curtailing our reliance on fossil fuels. Notably, the hydrogenation of to CO via reverse water–gas shift (RWGS) reaction (CO2 + H2 ↔ H2O) plays a pivotal role in commercial e-fuel production. This approach preferred over direct conversion CO2, remains nascent stage. However, endothermic RWGS energy-intensive it requires high operating temperatures (∼600–800 °C). Therefore,...
We report the development of Ru/Mg–Al oxide coated metal-structured catalysts with excellent heat and mass transfer characteristics for efficient clean H2 production from ammonia decomposition. Ammonia is a promising carrier transport hydrogen facilitates COx-free by decomposing into nitrogen hydrogen. Ru nanoparticles are uniformly dispersed on Mg–Al layer FeCralloy monoliths foams via precipitation. The catalytic activities depend surface area loading metal dispersion in layer. At...
The dependence of the catalytic activity and coke resistance Ni-based catalysts on support type was investigated in dry reforming methane (DRM). Catalysts were prepared using incipient wetness impregnation analyzed ICP-OES, BET-BJH, XRD, H2-chemisorption, H2-TPR, CO2-TPD. DRM performed at 600–750 °C 144,000 mL/gcat∙h GHSV (CH4/CO2/N2 = 1/1/1). Ni/Al2O3 Ni/MgO formed NiAl2O4 NiO-MgO solid solutions, respectively, owing to strong binding between metal support. In contrast, MgO-Al2O3 MgAl2O4...
Ni/zeolite 13X catalyst synthesized by deposition–precipitation exhibits improved low-temperature performance for NH 3 decomposition owing to high dispersion and uniform deposition of active Ni on the surface in pores zeolite support.
Sulfur‐rich materials have recently attracted keen interest for their potentials in optical, electrochemical, and pesticidal applications as well utility dynamic covalent bond chemistry. Many sulfur‐rich polymers, however, are insoluble processing methods therefore very limited. The synthesis characterization of water‐dispersible polymer nanoparticles (NPs) with the sulfur content exceeding 75% by weight, obtained from interfacial polymerization between 1,2,3‐trichloropropane sodium...
