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.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
