Design of the Synergistic Rectifying Interfaces in Mott–Schottky Catalysts

Chemical Reviews, 2022
The functions of interfacial synergy in heterojunction catalysts are diverse and powerful, providing a route to solve many difficulties in energy conversion and organic synthesis. Among heterojunction-based catalysts, the Mott-Schottky catalysts composed of a metal-semiconductor heterojunction with predictable and designable interfacial synergy are ...

Mott–Schottky analysis of thin ZnO films

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2000
Thin ZnO films, both native and doped with secondary metal ions, have been prepared by sputter deposition and also by casting from solutions containing a range of precursor salts. The conductivity and infrared reflectivity of these films are subsequently enhanced chemically following treatment in H2 gas at 400 °C or by cathodic electrochemical ...

THE FREQUENCY DEPENDENCE OF MOTT–SCHOTTKY PLOTS

Chemistry Letters, 1985
Abstract The charging current of the space charge layer of a CdS(0001)/aq. KCl junction was measured by Time Domain Spectroscopy in the short time region. The relaxation spectrum consists of a multitude of exponentials, which is interpreted by a heterogeneous semiconductor surface.

Variable Mott-Schottky plots acquisition by potentiodynamic electrochemical impedance spectroscopy

Journal of Solid State Electrochemistry, 2005
Potentiodynamic electrochemical impedance spectroscopy provides extraction of potential-dependent space charge layer capacitance from potentiodynamic impedance spectra of non-stationary semiconductor–electrolyte interface. The new technique has been applied for acquisition of Mott-Schottky plots of cathodically treated TiO2 anodic films.

Mott-Schottky electrocatalyst selectively mediates the sulfur species conversion in lithium-sulfur batteries

Journal of Colloid and Interface Science, 2023
The lithium sulfur (Li-S) battery is an active research area in the field of energy storage systems, but the shuttle effect is a serious obstacle hindering its application. Herein, a CoSe2/CoO Mott-Schottky catalyst is blended with carbon nanotubes (CNTs) and subsequently coated onto a commercial separator as a modifier, whereby the synergy between the

Defect Pyrochlore‐Type Mott–Schottky Photocatalysts for Enhanced Ammonia Synthesis at Low Pressure

Angewandte Chemie International Edition, 2023
AbstractThe ambient ammonia synthesis coupled with distributed green hydrogen production technology can provide promising solutions for low‐carbon NH3 production and H2 storage. Herein, we reported Ru‐loaded defective pyrochlore K2Ta2O6−x with remarkable visible‐light absorption and a very low work function, enabling effective visible‐light‐driven ...

Analysis of Electrodes Displaying Frequency Dispersion in Mott-Schottky Tests

Journal of The Electrochemical Society, 2008
A procedure is proposed for using the Mott-Schottky approximation to obtain the electronic properties (flatband potential and charge carrier density) of passive films that are modeled by equivalent circuits that contain a constant phase element (CPE) rather than a capacitor. Capacitances are calculated from the equivalent circuit containing a CPE using
