Summary: A bifunctional catalyst with Fe-N4 sites and Fe nanoparticles was synthesized by doping Fe in ZIF-8, which effectively enhanced the acid-base sites in ZIFs and promoted the conversion of microalgal lipids. Compared to the ZIF precursors, Fe nanoparticles and coordinated Fe ions in Fe-N4 sites increased Lewis acidity, while uncoordinated N atoms increased Lewis basicity. The adsorption energies of acetic acid on Fe-N4 and Fe NP were higher than that on the Zn-N4 site, and the energy barriers for rate-determining steps on Fe-N4 and Fe NP were lower than that on the Zn-N4 site. The maximum biodiesel yield achieved over Fe-NC catalyst was higher than that over ZIF-8 catalyst.

Summary: As a new type of porous organic materials, two-dimensional covalent organic frameworks (2D COFs) show superior visible-light harvesting and effective separation and transport of the photogenerated charges, which ensures COFs to be promising platforms for photocatalysis. In this study, two 2D imine-linked COFs (PDA-TAB and PDA-TTA) were synthesized to investigate the effects of the introduced triazine units in the skeleton of COFs on photocatalytic CO2 reduction. The results showed that PDA-TTA exhibited a much higher photocatalytic activity compared to PDA-TAB, with a HCOOH yield of 65.7 mu mol g(cat)(-1)h(-1). Further studies indicated that the introduction of triazine units in the skeleton of PDA-TTA not only enhanced the visible-light absorption but also promoted the charge separation and migration, thereby improving the photocatalytic performance. This work contributes to the understanding of the roles of key structural units in 2D COFs in photocatalysis and provides insights for the development of efficient photocatalysts for CO2 conversion.

Summary: This study provides a comprehensive investigation into the catalytic condensation of renewable 3-carene with formaldehyde for the one-step preparation of terpenoid trans-4-hydroxymethyl-2-carene. Various acids and alumino-silicates were found to catalyze the reaction, but the selectivity to the desired product was limited. Phosphoric acid showed the highest selectivity, and an excess of formaldehyde or catalyst loading significantly increased the yield of the target product. Water presence also led to increased selectivity. Additionally, a detailed mechanism for the 3-carene condensation with formaldehyde was proposed and confirmed through kinetic modeling.

The performance of CeO2 nanostructures with different morphologies in the carbonate interchange reaction (CIR) of alcohols was investigated, and the CeO2 nano-catalyst with rod morphology exhibited the highest oxygen vacancy and remarkable enhancement in conversion. The CeO2 characterization data revealed that the exposed active sites, defect density, coordination state of surface atoms, and reducibility of the catalytic materials are the contributing factors to its high catalytic activity.
