说明

Application

Ammonium Fluoride in Analytical Chemistry: Ammonium fluoride is extensively used in chromatographic analyses as demonstrated in the synthesis of bifunctional magnetic polymers for the pretreatment and determination of specific metabolites in plasma samples, enhancing both the selectivity and sensitivity of the detection processes (Sun et al., 2024).

Silica Synthesis: The compound is used in the activation mechanism for the synthesis of hydrated silica from industrial waste, showcasing its role in promoting environmental sustainability and material recovery (Duan et al., 2024).

Energy Storage Materials: In the field of energy storage, ammonium fluoride acts as a structuring agent in the systematic design of single metal compounds, which are crucial for developing advanced battery technologies (Kuo et al., 2023).

Environmental Safety and Photocatalysis: It also finds application in environmental safety and photocatalytic processes, where it is used to enhance the photocatalytic activity of materials for biomass conversion and CO2 reduction, contributing to cleaner energy solutions (Liu et al., 2023).
