Graphitic carbon nitride (g-C3N4, CN for short) is a compelling visible-light responsive photocatalyst. However, its photocatalytic efficiency is low due to the random carrier transfer in planes and insufficient redox potential. Herein, we build oxygen functional group modified sodium-doped carbon nitride (OH/Na co-functionalized carbon nitride) to promote directional transfer of charge carriers for acceleration of separation and enhance redox potential for efficient oxidation of NO in air. Specifically, the function of sodium atoms could control the directional transfer of random carriers from the intralayer to the oxygen functional group-modified surface for the purpose of effectively reducing photogenerated electron-hole recombination. Meanwhile, the modification by oxygen-containing functional groups could adjust the band structure of CN, thereby increasing the oxidation-reduction potential of NO in the photocatalyst. The transformation pathways and reaction mechanism of photocatalytic NO oxidation on CN and OH/Na co-functionalized carbon nitride have also been explicated by ESR spectroscopy and in situ DRIFTS and compared. This work provides a new method for simultaneously controlling the random transfer of carriers and adjusting the energy band structure of CN to optimize its photocatalytic efficiency. It is also possible to extend this strategy to improve the performance of other 2D layered catalysts for photocatalytic oxidation.

I found the field of Polymer Science very interesting.

Cu-Catalysed reversible-deactivation radical polymerisation of hydrophobic methacrylate monomers in anhydrous alcohols has been expanded to explore the scope of this unusual choice of solvent. A range of linear methacrylic homopolymers with well-targeted molecular weight and low dispersity (D = 1.12-1.53) have been generated in anhydrous methanol and isopropanol with relative ease. These solvents are normally considered antisolvents and employed to precipitate such polymers; therefore, our studies have assessed the polymerisation reaction mixture homogeneity and extent of reaction control. Statistical copolymerisations with the bi-functional monomer, ethylene glycol di-methacrlylate (EGDMA), has led to branched statistical copolymers with weight average molecular weights up to M-w = 1.76 x 10(6) g mol(-1); subsequent triple-detection size exclusion chromatography studies have provided insight into the impact of monomer structure on the extent of branching within the final isolated polymers. The ability to control branched copolymer molecular weights under these conditions through variation of EGDMA concentrations was seen to be highly dependent on methacrylate monomer chemistry. A number of factors which are likely to effect branching reactions during the polymerisation of hydrophobic methacrylates in anhydrous alcohols are discussed.

A highly versatile and efficient ultrasound promoted synthesis of xanthenedione derivatives is achieved through condensation of dimedone with various aromatic aldehydes using boric acid as catalyst in ethanol-water medium. The advantages of this method being, mild reaction conditions, short reaction time, easy work-up, purification of products by non-chromatographic methods and additionally this method provides excellent yields. Two of the Xanthendiones derivatives 3a and 3b gave good crystals on recrystallization and their molecular structures were confirmed by crystallographic studies. The molecules in the crystal lattice are held together by weak intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions. Further insights into these interactions using Hirshfeld surface analysis and DFT/B3LYP studies show that in compound 3a H center dot center dot center dot H (54.7%), O center dot center dot center dot H (18.3%) and in 3b H center dot center dot center dot H (53.7%), O center dot center dot center dot H (17.6%) are the major contributors to the intermolecular interactions which stabilize the crystal structures. In order to determine molecular electrical transport properties, we studied the energy difference between Highest Occupied, HOMO, and Lowest Unoccupied, LUMO orbitals and the HOMO and LUMO energy gap for compounds 3a and 3b was found to be 3.9261 eV and 4.6436 eV respectively. The 2D fingerprint plot provided percentage contribution of each individual atom-to-atom interactions. The Mulliken atomic charges and molecular electrostatic potential on molecular van der Waals surface were calculated to know the electrophilic and nucleophilic regions of the molecular surface.

A rhodium-catalyzed tandem intermolecular hydroacylation of terminal alkyne-substituted secondary alcohols with chelating aldehydes and deconjugative isomerization of the resulting alpha,beta-unsaturated ketones for the preparation of synthetically valuable 1,4-diketones is developed. Of note, the completely atom-economical protocol can be extended to the alkynyl alcohols with appropriate carbon chain length, from which 1,5-diketone and 1,6-diketone were obtained involving the short-range deconjugative isomerization. Given its robustness, broad substrate scope, and excellent regioselectivity, this approach provides a promising platform for the synthesis of diverse diketones.

Surface and interface engineering predominantly determines the overall surface dynamics, and the surface layers can benefit substantially from a chemically different underneath layer. Herein, we demonstrate the surface tuning of nickel ferrite (NiFe2O4) with awaruite (Ni3Fe). The NiFe2O4 grows in the form of a crystalline monolayer encompassing bimetallic Ni3Fe nanocrystals embedded within a polyaniline (PANI) matrix. This is achieved by a simple and highly reproducible chemical approach. Benzyl alcohol (BA) and PANI steer the growth of metallic Ni3Fe covered with a monolayer of NiFe2O4 under mild solvothermal conditions. PANI presumably renders anchoring sites and guides the formation of fine and monodisperse nanocrystals of NiFe2O4/Ni3Fe, while BA acts as a reducing agent and controls the nucleation and the growth of NiFe2O4. In the absence of PANI, the formation of large and agglomerated NiFe2O4 nanoparticles is observed. The fine interface created between the NiFe2O4 monolayer and Ni3Fe imparts unique and superior surface attributes; Ni3Fe renders a high electroactive surface area and faster charge transport, while the NiFe2O4 monolayer affords high catalytic ability. As a result, the NiFe2O4/Ni3Fe/PANI electrode efficiently catalyzes the oxygen evolution reaction (OER), and requires a substantially lower overpotential than those of NiO/PANI, NiFe2O4, and Fe2O3/PANI. The Tafel values suggest that the kinetics of the half-reaction at the catalytic interface of NiFe2O4/Ni3Fe/PANI is much faster (52.3 mV dec(-1)) than that of NiO/PANI (82.5 mV dec(-1)), NiFe2O4 (86.0 mV dec(-1)) and Fe2O3/PANI (108.3 mV dec(-1)). The turnover frequency of NiFe2O4/Ni3Fe/PANI is 0.27 s(-1), 5.4 fold higher than that of NiFe2O4 (0.05 s(-1)). Moreover, the electrochemically active surface area, electrochemical impedance, surface charge transport properties, and active sites of NiFe2O4/Ni3Fe/PANI and NiFe2O4 are estimated, compared and correlated to the OER performance. In addition, density functional theory calculations show a decrease in the barrier of the potential-determining step from *O to *OOH, indicating a favorable electronic modulation at the interface of NiFe2O4 and Ni3Fe, which reduces the overpotential requirement.

A silver-mediated aerobic approach to access 2-methyl-chromone-3-carboxylic acid from the reaction of 4-hydroxy coumarin and enol ester in the presence of base has been presented. Mechanistic investigation suggests that the base induced Michael-type addition reaction of 4-hydroxy coumarin to the enol ester resulting the sequential ring opening and closing with the liberation of acetone are the key-steps for the overall transformation. Theoretical calculation of energy of the intermediates by DFT supports the proposed reaction mechanism. (C) 2021 Elsevier Ltd. All rights reserved.
