Catalytic conversion of bioethanol to value-added chemicals and fuels: A review

Resources Chemicals and Materials, Journal Year: 2022, Volume and Issue: 1(1), P. 47 - 68

Published: Jan. 24, 2022

Bioethanol produced via valorisation of renewable biomass is great interest to many industries. The increased availability and decreased cost bioethanol make it a promising platform molecule produce wide range value-added chemicals fuels the catalytic conversions. This paper provides comprehensive review conversions variety chemicals/fuels such as hydrogen, C2–C4 olefins, gasoline small oxygenates. Specifically, focus was placed on relationship between catalyst property (such pore structure, acidity, active metal sites, supports) performance (including activity stability), well reaction mechanisms involved. Future research avenues design for improving are also discussed.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

Abstract The catalytic conversion of bioethanol to ethylene (C 2 H 4 ) and acetylene offers a transformative approach sustainable production two industrial cornerstones for organic compound polymer syntheses, thereby offering significant economic environmental advantages. In contrast, current methods the synthesis these C hydrocarbons rely on energy‐ carbon‐intensive processes that require high temperatures pressures. present work addresses limitations with novel, low‐energy, bioethanol‐conversion strategy operating at room temperature ambient pressure using sono‐piezo‐photocatalysts. A novel heterostructure graphene oxide fragments (GO) sodium bismuth titanate (NBT) within core‐shell microstructure achieved outstanding rates 134.1 55.5 µmol/g/h, respectively. mechanism is driven by (1) bubble collapse during ultrasound irradiation, generating localized (≈4000 K) pressures (≈100 MPa), (2) piezo‐photocatalytic tuning GO/NBT enhanced charge separation transfer. DFT simulations revealed detailed sono‐piezo‐photocatalytic pathways, showing reductions in energy barriers (22.0 kcal mol −1 (48.0 formation. These findings emphasize critical role catalyst cleaving both C─H C─O bonds effectively, leading desired product
