EcoEnergy, EarlyView.A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.
