Summary: The acylamide functionalized tetra-carboxylic acid (H(4)CDA) was used to synthesize two 3D-MOFs, Cd-CDA-MOF and Cu-CDA-MOF, with different network topologies. Cd-CDA-MOF exhibited efficient catalytic activity for Knoevenagel condensation reaction, while Cu-CDA-MOF showed excellent catalytic activity for Chan-Lam coupling reaction. The MOFs' catalytic activity is attributed to the coordinatively unsaturated open metal sites. Additionally, the MOFs demonstrated recyclability and stable catalytic activity.

Summary: The study presents a highly stable and ultrapermeable zeolitic imidazolate framework-8 (ZIF-8)-nanocrystal-hybridized graphene oxide membrane prepared using ice templating and in situ crystallization of ZIF-8. The selective growth of ZIF-8 in microporous defects enhances water permeability and mechanical integrity, leading to a 30-fold increase in permeability compared to graphene oxide membranes (GOms). The technique also improves permselectivity and offers potential for developing next-generation nanofiltration membranes.

Summary: Reductive catalytic fractionation (RCF) of lignocellulosic biomass is an important biorefinery strategy. In this study, a copper-based catalyst derived from a metal-organic backbone was used for RCF of woody sawdust, resulting in high yields of propyl and propanol end-chain monomeric phenols. The study also provided insights into the cleavage of aryl ether linkages and lignin valorization using non-noble catalysts.

Summary: The manner of bonding between constituent atoms or molecules affects the properties of materials. Porous frameworks exemplify this, with their connectivity modes giving rise to subclasses with unique properties. Chalcogen bonding, a subclass of s-hole bonding, is shown to be a viable mode of connectivity in low-density porous frameworks, expanding the diversity of porous framework materials.

Summary: Ni/CeO2 single-atom catalyst with regulated oxygen vacancies (OV) on CeO2 surface was synthesized and employed in dry reforming of methane (DRM) reaction. The catalyst with the highest OV concentration exhibited the highest activity retention and a high turnover frequency of methane. The synergistic combination of C-H activation function from Ni single-atom catalysts and CO2 activation function from OV facilitated efficient methane conversion and carbon removal in the OV-SAC catalytic system.

Summary: In this study, the efficient conversion of bagasse pith biomass to furfural was achieved using a carbon-based solid acid catalyst and a water-butyrolactone co-solvent system. The combination of the catalyst and co-solvent allowed for high furfural yield by breaking down the biomass structure and facilitating hydrolysis and dehydration reactions. The experiment resulted in a 90.5% furfural yield under specific conditions.
