What is Sn2+-Modified Silicotungstic Acid Catalyst about?

This study investigates the modification of silicotungstic acid (STA) with Sn2+ ions to enhance its catalytic activity for the acetylation of glycerol with acetic acid. Characterization techniques confirm the preservation of the Keggin structure and reveal the presence of both Bronsted and Lewis acidic sites, with the Sn1.5STA catalyst exhibiting the highest catalytic activity due to optimal acidity. The research highlights the potential of using modified STA as an efficient solid acid catalyst for glycerol
