A Strategy of Enhancing the Photoactivity of g-C3N4 via Doping of Nonmetal Elements: A First-Principles Study
TL;DR: In this article, an effective structural doping approach has been described to modify the photoelectrochemical properties of g-C3N4 by doping with nonmetal (sulfur or phosphorus) impurities.
Journal ArticleDOI
Origin of Photocatalytic Activation of Silver Orthophosphate from First-Principles
TL;DR: In this article, a density functional theory incorporating the LDA + U formalism has been used to investigate the origin of photocatalytic activation of Ag3PO4, which provides an improved band gap and the position of the valence band if both Up and Ud are used.
Journal ArticleDOI
Production of visible activity and UV performance enhancement of ZnO photocatalyst via vacuum deoxidation
TL;DR: In this article, a ZnO photocatalyst with surface oxygen vacancies was obtained via vacuum deoxidation method, where the concentration of surface oxygen vacancy could be controlled by tuning the temperature and time in vacuum, which governs the production of visible activity and the enhanced level of photocatalytic activity.
Journal ArticleDOI
Correlation Effects on Lattice Relaxation and Electronic Structure of ZnO within the GGA+U Formalism
TL;DR: In this paper, the electronic structures of ZnO were calculated using density functional theory, in which the electronic interactions are described within the GGA+U (GGA = generalized gradient approximation) formalism, where on-site Coulomb corrections are applied on the Zn 3d orbitals (Ud) and O 2p orbitals(Up).
Journal ArticleDOI
Effects of distortion of PO4 tetrahedron on the photocatalytic performances of BiPO4
TL;DR: In this paper, three kinds of crystal phase BiPO4 (HBIP, nMBIP and mMBIP) were selectively synthesized by a hydrothermal method and showed higher activity for degradation of MB solution under UV irradiation than HBIP, mMBIP and HBIP.
