Brønsted acid catalysts are a type of catalyst that function by donating protons (H⁺) to the reactants, facilitating various chemical reactions. These catalysts are named after the Danish chemist Johannes Nicolaus Brønsted, who, along with Thomas Lowry, developed the Brønsted-Lowry acid-base theory. In this theory, acids are defined as proton donors and bases as proton acceptors.
