In this work, we report a novel MoS/MnCdS composite catalyst that has been designed and fabricated by in situ coupling MoS nanoclusters with 1D MnCdS nanorods for photocatalytic H production. The catalyst features a 1D nanostructure with MoS nanoclusters uniformly dispersed along the MnCdS nanorod. It was found that an intimate interface is built between MoS nanoclusters and MnCdS nanorods thanks to the facile in situ photoreduction route, which contributes to a high-efficiency interfacial charge separation. The resulting MoS/MnCdS photocatalyst shows a dramatically enhanced visible-light-driven photocatalytic H production activity compared with the control samples, owing to more efficient spatial charge separation as well as enriched active sites. This work is expected to provide an optimized structure model for rational design and constructing novel, inexpensive, efficient and stable cocatalyst/metal sulfide photocatalyst systems for H production.

17β-estradiol (E2) and estriol (E3), as natural estrogen contaminants in aquatic environments, have significant risks to ecosystems and human health by disrupting endocrine functions and inducing reproductive disorders even at trace levels. To address the urgent need for simultaneous monitoring of these structurally similar targets, we developed a dual-potential electrochemiluminescence (ECL) immunosensor for efficient parallel detection of E2 and E3. The sensor employs poly (1-naphthylamine)-molybdenum disulfide decorated with gold-silver bimetallic nanoclusters (PNA-MoS@AuAg NCs) as an ECL emitter, utilizing the self-enhancing property of AuAg NCs for intermolecular charge transfer and dual-potential-responsive properties to generate two well-resolved ECL signals (-0.

Surface-enhanced Raman spectroscopy (SERS) holds immense promise for molecular detection, yet the quest for high-performance, plasmon-free substrates remains active. This work pioneers the rational design and engineering of phase-tunable MoS nanoclusters─metallic (1T), semiconductor (2H), and, critically, hybrid metal/semiconductor (1T/2H) phases as a novel class of SERS platforms. We demonstrate this exceptional capability for ultrasensitive detection of environmentally hazardous dyes (e.

Anti-icing coatings are increasingly being used in aerospace applications, polar expeditions, and offshore wind power. However, their mechanical strength and corrosion resistance often decrease in harsh environments, limiting their long-term durability. In this study, we developed a hard yet flexible anti-icing coating that demonstrated exceptional wear resistance and anticorrosion properties.

Noble metals offer a wide range of potential catalysis applications, particularly in fuel cells and supercapacitors. The decoration strategy is a promising efficient strategy to address the limited structural flexibility and enhance the performance of noble metal electrode materials. Herein, we report a facile method to synthesize the nanocomposites with Pt nanoclusters (NCs) decorated on the surface of 2H-MoS nanosheets (Pt NCs@2H-MoS).

Single-metal-atom chains (SMACs) possess a variety of unique properties and functionalities but suffer from ambient vulnerability due to their delicate one-atom-width structures. While some SMACs can be effectively stabilized by nanochannel confining, it remains a pressing challenge to experimentally realize more versatile atomic chains with sufficient stability and extended length. Here, we propose a computational protocol to identify transition metals capable of forming SMACs along mirror twin boundaries in two-dimensional metal dichalcogenides.
