Precision‐Engineered Nanocatalysts Via Lattice Tailoring and d‐Band Center Modulation for High‐Performance Lithium‐Sulfur Batteries

open access: yesCarbon Energy, EarlyView.
Benefiting from the dual‐defect engineering of P doping and oxygen vacancies, P‐Ov‐TiO2 catalysts with exposed {101} crystal facets possess optimized lattice structure and d‐band center. The synergistic effect accelerated the charge transfer and the long‐ and short‐chain LiPSs conversion kinetics.

Understanding the active site structures and achieving catalytic activity tuning of atomically dispersed FeN4 sites for oxygen reduction reaction

open access: yesChemPhysChem, Accepted Article.
Atomically dispersed Fe‐N‐C catalysts with high oxygen reduction reaction (ORR) activity have attracted great attention since the last decade. Due to its comparable ORR activity and low material cost, it is a promising platinum‐group metal (PGM) free catalyst that can replace the commercialized Pt/C materials; furthermore, it can facilitate the ...

Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

open access: yesChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated
