Abstract The rational design of a step‐scheme (S‐scheme) heterojunctions in hybrid semiconductors by avoiding unwanted charge transport paths is considered as an attractive way to achieve high photocatalytic activity hydrogen evolution reaction (HER). Here, dual S‐scheme heterojunction formed the lychee‐shaped W 18 O 49 /CdWO 4 /CdS nanostructures proposed for improving performance HER under visible light irradiation. remarkable attributed unique structure and effective separation photoinduced defect‐transit mechanism strong internal electric field. measurements X‐ray photoelectron spectroscopy (XPS), femtosecond transient absorption (fs‐TA) spectroscopy, electron paramagnetic resonance (EPR) further confirm carrier transfer pathways following mechanism. This research can provide new strategy designing improve through defect band engineering.

Essential role of lattice oxygen in hydrogen sensing reaction

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 8, 2024

Understanding the sensing mechanism of metal oxide semiconductors is imperative to development high-performance sensors. The traditional only recognizes effect surface chemisorbed oxygen from air but ignores lattice oxygen. Herein, using in-situ characterizations, we provide direct experimental evidence that participated in process can come oxides. Further density functional theory (DFT) calculations prove p-band center O serves as a state art for regulating participation gas-sensing reactions. Based on our data and theoretical calculations, discuss mechanisms are fundamentally different conventional show easily helpful high response value materials.

A Straightforward Solvent‐Pair‐Enabled Multicomponent Coassembly Approach toward Noble‐Metal‐Nanoparticle‐Decorated Mesoporous Tungsten Oxide for Trace Ammonia Sensing

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Июль 16, 2024

The straightforward synthesis of noble-metal-nanoparticle-decorated ordered mesoporous transition metal oxides remains a great challenge due to the difficulty balancing interactions between precursors and templates. Herein, solvent-pair-enabled multicomponent coassembly (SPEMC) strategy is developed for nitrogen-doped tungsten oxide (abbreviated as NM/N-mWO
