Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, Volume 28, Issue 2, Page 184-195, June 2026.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...

Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy, Volume 4, Issue 3, June 2026.
Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...
