The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

Carbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

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

Strain and Band Modulation of WO3/SnSe Micro‐Nano Composites Achieving Superior Photocatalytic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
WO3/SnSe micro‐nano composites demonstrate exceptional photocatalytic performance through synergistic strain and band modulation. Lattice strain modulation enhances methyl orange adsorption and visible light absorption, while Z‐scheme band alignment promotes efficient charge separation. The 2.5% WO3/SnSe composite achieves 99.71% degradation efficiency,

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...
