Direct propane dehydrogenation (PDH) to propylene is a desirable commercial reaction but highly endothermic and severely limited by thermodynamic equilibrium. Routes that oxidatively remove hydrogen as water have safety cost challenges. We coupled chemical looping-selective (H2) combustion PDH with multifunctional ferric vanadate-vanadium oxide (FeVO4-VOx) redox catalysts. Well-dispersed VOx supported on aluminum (Al2O3) provides sites, adjacent nanoscale FeVO4 acts an oxygen carrier for...
Redox catalysts play a vital role in chemical looping oxidative dehydrogenation processes, which have recently been considered to be promising prospect for propylene production. This work describes the coupling of surface acid catalysis and selective oxidation from lattice oxygen over MoO3-Fe2O3 redox promoted Atomically dispersed Mo species γ-Fe2O3 introduce effective sites promotion propane conversion. In addition, could also regulate activity, makes reduction Fe3O4 contribute selectively...
PtCu single-atom alloys (SAAs) open an extensive prospect for heterogeneous catalysis. However, as the host of SAAs, Cu suffers from severe sintering at elevated temperature, resulting in poor stability catalysts.

The suppression of methane and coke formation over Ni-based catalysts for low temperature ethanol steam reforming remains challenging. This paper describes the structural evolution Fe-modified Ni/MgAl2O4 influence iron species on reforming. Ni–Fe alloy are gradually oxidized by water to generate Ni-rich γ-Fe2O3 at steam-to-carbon ratio 4. electron transfer from nickel within weakens CO adsorption effectively alleviates CO/CO2 methanation. oxidation capacity promotes transformation ethoxy...
Propane dehydrogenation (PDH) exhibits promising potential for propylene production. However, the primary challenge of its application is development environmentally benign, low-cost, and high-performance catalysts as alternatives to CrOx- or Pt-based catalysts.
