TL;DR: In this article, a two-dimensional (2D) MoS2 nanosheets (NSs) modified 1D TiO2 nanorods/0D CdS nanocrystals (NCs) heterojunction has been fabricated by all solution process as a potential anode for photoelectrochemical (PEC) water splitting applications.
Journal ArticleDOI
Hydrogen Evolution Reaction at Anion Vacancy of Two-Dimensional Transition-Metal Dichalcogenides: Ab Initio Computational Screening
TL;DR: The catalytic activity for the hydrogen evolution reaction at the anion vacancy of 40 2D transition-metal dichalcogenides (TMDs) is investigated using the hydrogen adsorption free energy (Δ GH) as the activity descriptor and it is found that ZrSe2 and ZrTe2 have similar Δ GH as Pt, the best HER catalyst, at low vacancy density.
Journal ArticleDOI
Atomically thin two-dimensional materials as hole extraction layers in organolead halide perovskite photovoltaic cells
TL;DR: In this paper, two-dimensional materials such as MoS2, WS2, and graphene oxide (GO) are used as hole extraction layers (HEL) in organolead halide perovskites solar cells (PSCs) instead of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) HEL.
Journal ArticleDOI
Two-Dimensional Transition Metal Disulfides for Chemoresistive Gas Sensing: Perspective and Challenges
TL;DR: In this article, a review of recent progress on the chemoresistive gas sensing properties of two-dimensional transition metal disulfides is provided, where the authors provide various methods to enhance the gas sensing performance of 2D disulfide, such as surface functionalization, decoration receptor functions and developing nanostructures.
Journal ArticleDOI
