Nonstoichiometric defects, as manifested by slight deviation of elemental compositions from
chemical formulas, are common yet highly important in solid materials. Oxynitrides with a …

Presented herein is a detailed discussion of the properties of the lattice dynamic and
optoelectronic properties of tantalum (V) oxynitride (TaON) and tantalum (V) nitride (Ta 3 N …

Cupric oxide (CuO) is an attractive photocathode material for tandem-type
photoelectrochemical water-splitting because it has a small bandgap (1.2–1.5 eV), high …

We propose an in situ UV–vis monitoring technique called “oxynitrogenography” as an
approach toward the controlled and reproducible synthesis of thin films of different Ta–O–N …

Tantalum oxynitride thin films have been deposited by reactive magnetron sputtering, using
a fixed proportion reactive gas mixture (85% N2+ 15% O2). To produce the films, the partial …

Finding an ideal photocatalyst for achieving efficient overall water splitting still remains a
great challenge. By applying accurate first-principles quantum calculations based on DFT …

Tantalum nitride (Ta3N5) and oxynitride (TaON) are promising materials for
photoelectrochemical (PEC) water splitting due to near-ideal band gaps and band edge …

Hematite (α-Fe2O3) is an attractive candidate for photoelectrochemical (PEC) hydrogen
generation by oxidation of water due to its low cost, earth-abundance and appropriate …

Abstract Nitrogen-doped Ta 2 O 5 (N-Ta 2 O 5) powders were fabricated by nitridation of Ta
2 O 5 in NH 3 for 1 h at 600–700° C. The concentration of nitrogen doping increased as the …

Mixed anion semiconductors such as oxynitrides offer a wide range of properties that can be
tuned for various catalytic applications, such as photocatalytic water splitting. In this work …
