Experimental demonstration of vanadium-doped nanostructured ceria for enhanced solar thermochemical syngas production

Solar-driven thermochemical routes enable storage of solar energy in chemical form for off-sun use by means synthetic fuel production. Here, we explore vanadium-doped ceria materials partial oxidation methane, followed an efficient splitting CO2 and H2O into syngas. The primary role the dopant is to enhance optimize cycle capacity at low isothermal temperatures. intake lattice reached its saturation level with 5% vanadium addition further increase V (%) forms a secondary phase (CeVO4), which significantly affects towards syngas production performance enhancement. For instance, atoms migrate powder surface ≥ cause cracking while (V < 5%) enhances providing reducing sites redox reactions improve oxygen mobility inducing distortions. V-doped four times higher than pure ceria, temperature methane reaction decreased up 178 °C elevated peak rates, after doping. long-term activity 200 cycles 4.5 mmol g−1/cycle reported. This study demonstrates concept utilizing produce via high looping reforming helps strategically evaluate as carrier
