“…It was concluded that catalytic pyrolysis of heavy crude oil over calcium aluminate achieved a maximum alkene yield of 36.89% for the dehydrogenation, while the highest aromatics of 57% was obtained over ZSM-5 due to the high acidity. However, the high acidity of ZSM-5 could lead to 56 as well. A catalyst with combined base and acid characteristics was prepared in this research.…”

“…Pyrolysis reactions with acid-base bifunctional catalysts produce high-value products while minimizing waste. The researchers, Yang et al, prepared a series of MgAl mixed metal oxide catalysts with varying acidity and alkalinity [57]. They achieved this by adjusting the Mg/Al ratio in the precursor of MgAl LDHs.…”

Layered double hydroxides (LDHs) have emerged as promising catalysts for various acid–base catalytic reactions. Due to their unique structure and regulatable dual acid–base properties, they offer more environmentally friendly and sustainable alternatives to traditional liquid acid and base catalysts. This study introduces the structural composition, preparation methods, and acid–base catalytic properties of LDH-based catalysts. Recent application progress in LDHs and rehydrated LDHs, LDH-based metal nanocatalysts, and LDH-based mixed metal oxide catalysts used as solid acid–base catalysts in acid–base green catalytic conversion is reviewed. The challenges and prospects of LDH-based catalysts as green and sustainable catalysts are summarized and proposed.
