Electronic Modulation of Pt Nanoparticles Induced by Defective TiN Promotes Highly Efficient Hydrogen Evolution

open access: yesCarbon Energy, EarlyView.
A nonequilibrium high‐temperature shock method was used to load Pt nanoparticles onto nitrogen vacancy‐rich TiN, enabling strong EMSI modulation. The Pt@TiN‐VN catalyst shows high HER activity (15.99 A mgPₜ⁻¹ at 100 mV) and 60‐h stability. Nitrogen vacancies optimize charge transfer and Pt–H bonding, offering insights into defect‐engineered ...

Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

open access: yesCarbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...
