Sub-nanometer PtSn Alloyed Clusters for Propane Dehydrogenation Performance Data

904.6 MB of data from figshare details a catalyst achieving about 1 molC3H6·gcatalyst-1·h-1 propylene productivity at 165 h⁻¹ weight-hourly space velocity for over 300 hours. Author Shangchen Lu uploaded the dataset on 2026-05-27 under a CC-BY-4.0 license. The research attributes high performance to the electronic structures of Pt sites within sub-nm alloyed clusters.

Use Cases

• Training ML models for catalyst performance prediction based on cluster size and alloy composition.
• Analyzing the trade-off between productivity and stability in dehydrogenation catalysts.
• Benchmarking regeneration methods for spent catalysts based on air calcination results.
• Studying the relationship between electronic structure and selectivity in catalytic reactions.

Strengths

• Dataset size is 904.6 MB, indicating substantial underlying data.
• Performance metrics are specific: >99% propylene selectivity and sustained productivity for over 300 hours.
• Includes details on catalyst regeneration via simple air calcination.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
