Hydrophobic, Acid-Free Zeolite-Confined Pt–Cu Nanoalloys Break Activity–Selectivity Limits in Low-Temperature Methane-to-Methanol Oxidation Open
The direct oxidation of methane (CH4) to methanol (CH3OH) remains a formidable challenge due to the inertness of CH4 and the tendency of CH3OH to overoxidize. Here, we report Pt-Cu nanoalloys enc…

Mechanism Responsible for Changes in the Luminescence Properties of Terbium (III)–Doped Layered Double Hydroxides During Carbonate/Chloride Exchange Open
Layered double hydroxides (LDHs) have been actively studied as water purification, battery, capacitor, and catalytic materials because they exhibit anion‐exchange capabilities. Furthermore, photoluminescent LDHs are potentially useful as m…
