Kinetics Analysis of the Syngas Fermentation to Produce Acetic Acid from Cardoon Residual Biomass

Chemical Engineering Transactions, 2022
Lignocellulosic biomass can be converted to biofuels and biochemicals through several process pathways: pretreatment and sugars fermentation, thermochemical conversion (pyrolysis, gasification) and syngas synthesis.

Niδ+ Atoms Anchored In Situ on Ultrathin Ni‐Phyllosilicate Nanosheet Ensure High‐Efficient CO2 Reduction into CO at Moderate‐Low Temperature

Advanced Science, EarlyView.
A novel supported Ni‐based catalyst, consisting of abundant Niδ+ atoms with low electron density anchored in situ on ultrathin Ni‐phyllosilicate nanosheet (a‐Niδ+−PSNS, 0< δ ≤1), achieve simultaneous outstanding CO2 conversion and CO selectivity. Their ultrathin nanosheet enables abundant anchored Niδ+ atoms to fully expose and disperse, which can ...

Microwave Ultrafast Heating on Iron‐based Nanogap Catalysts for CO2 Reduction Coupling with Coke Removal

Advanced Science, EarlyView.
This study employs a nanogap‐induced microwave discharge strategy to pretreat coke deposits on iron‐based catalysts with engineered nanogaps, causing ultrarapid heating to 1990 K within seconds, selectively eliminating >70% surface carbon deposits and converting waste plastics and greenhouse gases into syngas.

Quantification of Gaseous Products Evolved at Industrially Relevant Current Densities During CO2 Electroreduction and Water Electrolysis Using Online Gas Chromatography

Advanced Energy and Sustainability Research, EarlyView.
The dilution of gaseous products obtained at high‐current densities during CO2 electroreduction or water electrolysis enables their accurate quantification via online gas chromatography, which is crucial for reliable catalyst benchmarking. The corresponding Faradaic efficiencies can then be calculated with low deviations using two different instruments,
