TL;DR: In this paper, a nanostructured bismuth (Bi) nanoflakes were designed and directly grown on Cu substrate using a novel pulse electrodeposition method, which showed a high HCOO- faradaic efficiency (FE = 79.5%) at low potential of −0.4 VRHE and achieved a maximum FE close to 100% at − 0.6 VRHE.

TL;DR: In this paper, the authors demonstrate that wafer-scale, transferable, and transparent thin-film catalysts based on MoS2, which consists of cheap and earth abundant elements, can provide a low onset potential of 1 mA cm−2 at 0.17 V versus a reversible hydrogen electrode and the high photocurrent density of 24.6 m

TL;DR: In this article, the authors report the synthesis and photoelectrochemical (PEC) properties of various BiVO4-based heterojunction anodes based on stoichiometric Bismuth vanadate (BiVO4) by pulsed electrodeposition.

TL;DR: In this paper, the characteristic differences between MoS2 and WS2 nanosheets and nanodots are investigated, and it is shown that most of the nano-heets were approximately 0.7-2 nm thick, with slight deviation.

TL;DR: In this paper, the authors demonstrated chemoresistive humidity sensors with fast response, excellent selectivity, and ultrahigh sensitivity based on 2D reduced graphene oxide (rGO) and 2D MoS2 hybrid composites (RGMSs).
