A color and fluorescence turn-on H₂S probe is synthesized, achieving real-time detection of H₂S in pure water solution with high selectivity. Importantly, the probe is able to sense H₂S gas in air via the probe-deposited test paper, which has been successfully used for food spoilage identification.

The hydrogen storage properties, regulation methods and applications of Ti–Mn hydrogen storage alloys were reviewed.

Benefiting from the double-crack structure, sensors show ultra-high sensitivity, a wide working range and great value in the human–machine interaction.

Hydrogen energy is an excellent carrier for connecting various renewable energy sources and has many advantages. However, hydrogen is flammable and explosive, and its density is low and easy to escape, which brings inconvenience to the storage and transportation of hydrogen. Therefore, hydrogen storage technology has become one of the key steps in the application of hydrogen energy. Solid-state hydrogen storage method has a very high volumetric hydrogen density compared to the traditional compressed hydrogen method. The main issue of solid-state hydrogen storage method is the development of advanced hydrogen storage materials. Metal borohydrides have very high hydrogen density and have received much attention over the past two decades. However, high hydrogen sorption temperature, slow kinetics, and poor reversibility still severely restrict its practical applications. This paper mainly discusses the research progress and problems to be solved of metal borohydride hydrogen storage materials for solid-state hydrogen storage.
