Summary: The study investigated the electrocatalytic CO2 reduction using helical Cu-porphyrinic MOF grown on Cu(OH)(2) nanoarrays. The results showed that the helical MOF exhibited higher acetic acid Faradaic efficiency compared to the non-helical MOF, possibly due to better space utilization and stronger CO linear adsorption. This study developed new helical nanomaterials and proposed a new route to enhance the reduction of CO2.

Summary: An effective method for tuning CO2 adsorption, activation and transformations of epoxides in CO2 fixation reactions is the introduction of functional groups into the pores of metal-organic frameworks (MOFs) through ligand modification. In this study, a novel ionic ligand, H2BPDC-[TBD]Br-+(-), was synthesized to construct derivatives of the cationic guanidinium-containing Zr-MOF (UiO67-[TBD]Br-+(-)) with free bromide ions, as multifunctional heterogeneous catalysts. The synthesized UiO67-[TBD]Br-+(-) exhibited efficient catalytic performance in the CO2 fixation reaction with epoxides, showing high yield and selectivity under mild conditions.

Summary: Photocatalytic water splitting using a semiconductor is an effective way to obtain clean energy. However, pure semiconductors have poor photocatalytic performance due to charge carrier recombination, limited light harvesting ability and deficiency of surface reactive sites. In this study, a new UiO-66-NH2/CdIn2S4 (NU66/CIS) heterojunction nanocomposite was synthesized using the hydrothermal method, which showed improved performance in water reduction. The NU66/CIS heterojunction had intimate connections and promoted effective transfer of electrons, resulting in enhanced H-2 production. This research offers a creative idea for constructing active MOF-based photocatalysts for H-2 evolution.

Summary: A novel covalent organic framework (COF) (Tp-BI-COF) was successfully synthesized through a cascade of ketimine condensation followed by aldimine condensation. Tp-BI-COF showed high stability towards acid, organic solvent, and boiling water, and exhibited photochromic properties after irradiation with a xenon lamp. The stable COF with aligned one-dimensional nanochannels provided nitrogen sites on pore walls, which confined and stabilized H3PO4 in the channel via hydrogen-bonding interactions. After loading with H3PO4, the material showed excellent anhydrous proton conductivity.
