Hierarchical USY Zeolite Synthesis Data for Phenol Alkylation Catalysis

A study of hierarchical USY zeolite preparation via surfactant/ammonia post-treatment at temperatures from 40–135 °C. The dataset likely contains material properties like surface area (324–418 m² g⁻¹ mesoporosity, 413–363 m² g⁻¹ microporosity) and catalytic performance metrics for phenol alkylation with isopropanol. The data was authored by Cristina Molina and harvested from e-cienciaDatos Dataverse, with a last update timestamp of 2026-07-19.

Use Cases

• Modeling the relationship between synthesis temperature and mesopore uniformity based on described pore sizes around 4.0 nm.
• Predicting catalyst selectivity for C-alkylation products based on the reported Si/Al atomic ratio (48–52) and treatment conditions.
• Optimizing phenol conversion in alkylation reactions using the performance data for samples like USY-60, which showed 84% selectivity towards C-alkylation.
• Analyzing the trade-off between microporosity retention and mesoporosity generation under different hydrothermal synthesis times of 20 h.

Strengths

• Specific material property ranges are provided, including Si/Al atomic ratio (48–52) and surface areas for mesoporosity (324–418 m² g⁻¹) and microporosity (413–363 m² g⁻¹).
• Catalytic performance metrics are detailed, such as phenol conversion, selectivity towards C-alkylation products (up to 84%), and selectivity towards 2,6-diisopropylphenol (43%).
• Synthesis parameters are explicitly defined, including temperature range (40–135 °C), ammonia concentration (0.05 N), and treatment time (20 h).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's structure and file formats are unspecified, requiring inspection upon access.
