A machine vision tool for multi-color HO sensing by MoOx nanoparticles with oxygen vacancies.

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.

MoO with the Synergistic Effect of Sulfur Doping and Oxygen Vacancies: The Influence of S Doping on the Structure, Morphology, and Optoelectronic Properties.

Molybdenum trioxide (MoO) is an attractive semiconductor. Thus, bandgap engineering toward photoelectronic applications is appealing yet not well studied. Here, we report the incorporation of sulfur atoms into MoO, using sulfur powder as a source of sulfur, via a self-developed hydrothermal synthesis approach.

MoOx-Based Colorimetric Sensor for Ultraviolet Visualization.

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.
