TL;DR: In this paper, the gas sensing properties of monoclinic phase BiVO4 porous films with high selectivity and low detection limit towards H2S were reported for the first time, where the porous film with honeycomb-like morphology was in situ synthesized based on the solution dipping strategy using monolayer colloidal crystal as template.

TL;DR: In this article, an efficient strategy of boosting the charge transfer of hematite photoanode by decorating the grain boundaries in Fe2O3 film with TiO2 based on a simple chemical bath deposition was proposed.

TL;DR: In this article, two gradient Ti-doped Fe2O3 photoanodes were demonstrated to enhance charge transport and separation efficiency for solar water splitting, and they showed that the enlarged contact area between hematite photoanode and the electrolyte, the improved charge separation efficiency, and increased charge carrier density are responsible for the enhanced PEC water splitting.

TL;DR: In this article , a dual interfacial layers, accessed via grafting laser-generated carbon dots with phenolic hydroxyl groups (LGCDs−PHGs), are experimentally verified effective, not only in generating the uniform layer of LGCDs with covalent anchoring for inhibited photocorrosion, but also in activating, respectively, the charge separation and transfer in each layer for boosted charge-carrier kinetics, resulting in FeNiOOH-LGCD-PHGs-MBVO photoanodes with a dual configuration with the photocurrent density of 6.08 mA cm−2 @ 1.23 VRHE, and operational stability up to 120 h @ 1
