Cu‐SSZ‐13 Catalysts Designed Through Interzeolite Conversion Process From Different Structure Types of Zeolites for NH3‐SCR‐DeNOx: Structure‐Property Activity Relationships and Intermediates Determination

ChemCatChem, EarlyView.
A set of Cu‐SSZ‐13 zeolite samples (CHA structure type) was designed and developed to employ different starting zeolite materials (i.e., FAU, BEA, MFI). The investigations provide a pathway to gain deeper insights into the relationships between the structure and activity of these zeolite‐based materials in NH3‐SCR‐DeNOx.

Electron Relay Boosts Ruthenium‐Laccase System Photo‐Epoxidation

ChemCatChem, EarlyView.
Light‐driven oxidation of olefin to epoxide is achieved with a laccase/[Ru(bpy)3]2+ system and methyl viologen (MV2+), boosting p‐styrene sulfonate conversion from 3% to 14% (5‐fold yield increase) and enhancing epoxidation selectivity. Laccase steers selectivity by scavenging superoxide.

Dynamic Molten Cu–In Droplets Catalyze Selective Synthesis of Multi‐Walled Carbon Nanotubes During Methane Pyrolysis

ChemCatChem, EarlyView.
Isolated molten Cu–In alloy nanodroplets are shown to grow highly selective multi‐walled carbon nanotubes (MWCNTs) during clean H2 production via methane pyrolysis. The droplets exhibit a dynamic geometry during MWCNT growth, elongating, and growing smooth and bamboo‐like MWCNTs.

Electron Spin Polarization Facilitates the Urea Oxidation Reaction

ChemCatChem, EarlyView.
We show that on a spin‐aligned surface, urea adsorbs through its oxygen atom, favoring an intramolecular reaction pathway that predominantly yields the desired products such as N2 and CO2. In contrast, on a spin‐misaligned surface, urea adsorbs through its nitrogen atoms and proceeds via an intermolecular pathway, leading to overoxidation and the ...
