Abstract A non‐metal catalytic system consisting of dimethylglyoxime (DMG) and N ‐hydroxyphthalimide (NHPI) for the selective oxidation hydrocarbons with dioxygen is described. The synergistic effect DMG NHPI ensures its efficient ability: 82.1% conversion ethylbenzene 94.9% selectivity acetophenone could be obtained at 80 °C under 0.3 MPa in 10 h. Several were efficiently oxidized to their corresponding oxygenated products mild conditions.

Polydopamine (PDA)-coated or encapsulating Cu3(PO4)2 (Cu3(PO4)2@PDA) nanosheets were synthesized, allowing the C-reaction protein (CRP) antibody to be attached electrostatically for immunosensing of CRP with simple photothermal detection. The antibody-covered Cu3(PO4)2@PDA replace antibody-conjugated enzyme in enzyme-linked immunosorbant assays. Owing high surface area 2-D-structured and coabsorption light near-IR spectrum by PDA, a small amount confined wells titer plate generates an easily...

Co/Fe bimetallic spherical nanomaterials were synthesized by hydrothermal method as an efficient heterogeneous catalyst, which can catalyze the selective oxidation of benzyl alcohol to benzaldehyde O2, thereby replacing stoichiometric reagents such chromate and manganese oxide. CoFe2O4 has good activity selectivity for alcohol. The catalyst catalyzes preparation formaldehyde from oxide O2 at 150 °C, with a conversion rate 95.3% yield 96.7%. Furthermore, is recycled 5 consecutive uses without...

Abstract The aerobic oxidation of alcohols to their corresponding carbonyl compounds could be efficiently accomplished by using the combination cobalt nitrate, dimethylglyoxime and 2,2,6,6‐tetramethylpiperidine 1‐oxyl (TEMPO) as a novel catalytic system, various including primary secondary benzylic, allylic aliphatic quantitatively converted aldehydes or ketones at 70 °C under 0.4 MPa dioxygen pressure in dichloromethane. During oxidation, situ generated cobaloxime nitric oxide (NO) were...

Solvatochromic fluorescent probes are crucial molecular tools to investigate and aggregate proteins' fold, visualize fine structures in biomembranes, label different organelles dual emission colors. However, solvatochromic fluorogens often displayed a weak at high polarity, hindering their bioimaging applications. To resolve this problem, herein, we propose an intramolecular charge transfer (ICT) inhibition strategy. The probe was designed with single electronic donor two acceptors order...

A uniformly dispersed two-phase Cu/Cu2O NPs@graphene was obtained via an innovative "take" and "off" synthesis strategy with a Cu-MOF-derived jacket structure. The electron transfer between the Cu phase Cu2O leads to synergistic effect of Cu(0)-Cu(i) for efficient catalysis Sonogashira cross-coupling reactions.
