Metal-Free Single Atom Catalyst for N2 Fixation Driven by Visible Light.
TL;DR: In this article, a metal-free photocatalyst for solar-driven nitrogen reduction was proposed by using extensive first-principles calculations, which showed that gas phase N2 can be efficiently reduced into ammonia using B/g-C3N4 through the enzymatic mechanism with a record low onset potential (0.20 V).
Journal ArticleDOI

TL;DR: It is demonstrated that the trap states in 2D ReS2 can be efficiently modulated by defect engineering through molecule decoration, providing a solution to achieve photodetectors with both high responsivity and fast response.
Journal ArticleDOI
Janus MoSSe/WSeTe heterostructures: a direct Z-scheme photocatalyst for hydrogen evolution
TL;DR: In this article, the authors predict a Janus MoSSe/WSeTe heterostructure as a potential direct Z-scheme photocatalyst for hydrogen evolution based on density functional theory and nonadiabatic molecular dynamics calculations.
Journal ArticleDOI
Anomalous Size Dependence of Optical Properties in Black Phosphorus Quantum Dots
TL;DR: In this paper, the size-dependent electronic, optical absorption, and emission properties of black phosphorus quantum dots (BPQDs) were systematically studied by employing time-dependent density functional theory calculations.
