Due to the depletion of the global ozone layer and the presence of ozone holes, humans are increasingly exposed to threats from solar ultraviolet radiation. Therefore, researching and developing a highly selective, sensitive, simple, and fast ultraviolet sensor is of significant importance for personal protection. In recent years, new nanomaterials have shown good application prospects in the research of ultraviolet sensors. MoOx nanostructures were prepared by a hydrothermal method. The experimental results show that, compared to traditional photochromic compounds, the new MoOx nanostructures exhibit high uniqueness, high selectivity, and excellent stability, and can perform rapid and accurate detection under full-band light. The beam sensor can not only detect through traditional electrical signal output, but also amplify, display, and analyze the beam through visualization and visual analysis, further improving the reliability and practicality of its application.

The abuse of antibiotics has seriously threatened human health and living environment. Nevertheless, the detection of quinolones is currently mainly performed by high-cost and cumbersome means, such as High-Performance Liquid Chromatography (HPLC). Herein, we reported a novel method based on copper-doped MoO nanoparticles (Cu-MoO NPs) with peroxidase-like enhancement activity for the easy preparation, sensitive and rapid visualization of quinolone detection.

Defect engineering is a key chemical tool to modulate the electronic structure and reactivity of nanostructured catalysts. Here, it is reported how targeted introduction of defect sites in a 2D palladium metallene nanostructure results in a highly active catalyst for the alkaline oxygen reduction reaction (ORR). A defect-rich WO and MoO modified Pd metallene (denoted: D-Pd M) is synthesized by a facile and scalable approach.

Improving the ease of operation and portability of hydrogen peroxide (HO) detection in daily production and life holds significant application value. However, it remains a challenge to achieve rapid colorimetric detection of HO and color change quantification. In this study, we achieved rapid and visual detection of HO by MoOx (2 ≤ x ≤ 3) nanoparticles with rich oxygen vacancies using machine vision.
