Abstract This study explores the synthesis of ZSM‐5 zeolite using high‐purity mesoporous silica exclusively derived from coal fly ash (CFA), eliminating need for additional or alumina sources. Traditional relies on costly and environmentally harmful pure chemicals, whereas this approach utilizes CFA, an industrial byproduct, addressing both cost sustainability concerns. The synthesized demonstrates exceptional purity, with a surface area 455.24 m 2 /g, exhibits unique structural properties, confirmed through XRD, SEM, TEM, FTIR, TGA, BET analyses. method highlights potential CFA‐derived as sustainable feedstock production, promoting environmental cost‐effective applications in catalysis, adsorption, separation processes.

Zeolite is increasingly recognized for its enhancement of low-frequency acoustic performance in microspeakers. The aging characteristics zeolite have been regarded as the critical factor commercial viability mobile phones products, but mechanism remains ambiguous. Here, hierarchically structured ZSM-5 was investigated through with water and acetic acid (AA). It discovered that vapor augmented resonance offset it enhanced structure zeolite, resulting a lower content. significantly decreased after adsorption AA vapor, excessive adsorbed both physical chemical adsorption, causing partial destruction supermicropore mesopores. ZMS-5 stored mixture did not deteriorate, indicating effectively protected pores to prevent AA. This attributed fact by Brønsted sites more preferentially than AA, thereby avoiding
