Engineering of the d‐Band Center of Perovskite Cobaltite for Enhanced Electrocatalytic Oxygen Evolution

ChemSusChem, 2020
AbstractGreat efforts have been made to understand and upgrade the kinetically sluggish oxygen evolution reaction (OER). In this study, a series of V‐doped LaCoO3 (V‐LCO) OER electrocatalysts with optimized d‐band centers are fabricated. When utilized as an electrode for the OER, as‐formed LaCo0.8V0.2O3 (V‐LCO‐II) requires an overpotential of only 306 ...

Co‐Adjusting d‐Band Center of Fe to Accelerate Proton Coupling for Efficient Oxygen Electrocatalysis

Small, 2023
Abstract The problem in d‐band center modulation of transition metal‐based catalysts for the rate‐determining steps of oxygen conversion is an obstacle to boost the electrocatalytic activity by accelerating proton coupling. Herein, the Co doping to FeP is adopted to modify the d‐band center of Fe.

d-Band Center of Rare Earth Oxides Determines Biotransformation-Induced Cell Membrane Damage

Environmental Science & Technology, 2023
Biotransformation of rare earth oxide (REO) nanoparticles on biological membranes may trigger a series of adverse health effects in biosystems. However, the physicochemical mechanism of the complicated biotransformation behavior remains elusive. By investigating the distinctly different biotransformation behavior of two typical REOs (Gd2O3 and CeO2) on

Long‐Life Regenerated LiFePO₄ from Spent Cathode by Elevating the d‐Band Center of Fe

Advanced Materials, 2022
AbstractA large amount of spent LiFePO4 (LFP) has been produced in recent years because it is one of the most widely used cathode materials for electric vehicles. The traditional hydrometallurgical and pyrometallurgical recycling methods are doubted because of the economic and environmental benefits; the direct regeneration method is considered a ...

Precise Tuning of the D-Band Center of Dual-Atomic Enzymes for Catalytic Therapy

Journal of the American Chemical Society
Single-atom nanozyme-based catalytic therapy is of great interest in the field of tumor catalytic therapy; however, their development suffers from the low affinity of nanozymes to the substrates (H2O2 or O2), leading to deficient catalytic activity in the tumor microenvironment. Herein, we report a new strategy for precisely tuning the d-band center of
