This analysis demonstrates that boron doping improves catalytic performance in propane dehydrogenation, highlighting methods and stability implications.
This study synthesized B-S-1 supports with varying boron contents using two distinct methods: hydrothermal crystallization and microwave heating. Comprehensive characterization via XRD, FT-IR, Raman, and UV-vis spectroscopy verified the successful incorporation and framework crystallization of boron atoms within the S-1 structure. The boron-modified supports were then used to synthesize vanadium-based catalysts, which were evaluated for their performance in propane dehydrogenation. Results revealed that catalysts with a Si/B molar ratio of 20 exhibited the highest activity. Additionally, boron incorporation significantly enhanced the catalyst’s operational stability during prolonged reaction periods.
