In this paper, one supermolecular compound, namely, p-[C20H18N2O4][Mo8O26]0.5·H2O (1) has been synthesized from 1,4-bis[4-nitrile-pyridine)-N-methylene]phenyldibromide (L1) and (NH4)6Mo7- O24·4H2O by hydrothermal method. The structure has been confirmed through single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR spectra. The adsorption property of compound 1 has bee studied, Thus it’s much important to enrich the types of chemicals.
Blue-emitting gels are scarce, especially oligomeric/polymeric systems. New oligourethanes display aggregation-induced emission and form blue fluorescent gels with extensive hydrogen bonding and oxygen cluster interactions between chains.
Abstract
Anatase TiO2 hollow nanoboxes were synthesized and combined with the graphene oxide to get nanocomposite of TiO2/rGO (TG). Graphene oxide was used to modify the Oxygen-Clusters and bulk to surface defects. Anatase and TG composite were characterized with the positron annihilation, XPS, EPR, EIS and photocurrent response analysis. The relative affects of defects on the photocatalytic reduction (CO2 to CH4) were studied. The TG composites showed highest photo-catalytic activity after GO coupling (49 µmol g−1 h−1), 28.6 times higher photocurrent yields much higher quantum efficiency (3.17%@400 nm) when compared to the TiO2 nanoboxes. The mechanism of enhanced photo-catalytic CO2 conversion to CH4 elucidated through electrochemical and photo-catalytic experiments with traceable isotope containing carbon dioxide (13CO2). For the first time we discovered that diminishing the comparative concentration ratio of anatase from the bulk to surface defects could significantly increase the conversion of CO2 to CH4.
Metal–oxygen cluster (Fe28) was certified to own inherent peroxidase-like performance, which displayed multi-functional applications in H2O2, glucose and dopamine detection.
