Summary: A synergetic strategy for in situ synthesis of porous Na3V2(PO4)(3) (NVP) using reduced graphene oxide (rGO) and nanocellulose as additional carbon sources is proposed. The highly graphitized rGO substrate effectively hinders the agglomeration of NVP particles, while the carbon coating layers generated by the carbonization of nanocellulose construct an interconnected conductive network with rGO substrate. The dual-carbon coated network significantly improves the electronic conductivity and enhances the kinetic characteristics of NVP.

Summary: Recent research has shown that NASICON-type compounds, typically considered ideal candidates for AZIBs due to their large ionic channels and fast kinetics, may not be suitable after all due to their structural instability. Two NASICON structures, Na3V2(PO4)(3) and Na3V2(PO4)(2)F-3, were found to undergo structural decomposition in 1 M Zn(CF3SO3)(2) electrolyte during repeated cycling, with Na3V2(PO4)(3) degrading into Zn3V2O8, V2OS, and VO2 and Na3V2(PO4)(2)F-3 decomposing into V2O5, VPO5, and Zn-3(OH)(2)V2O7 center dot 2H(2)O. The decomposition mechanisms are attributed not only to inherent instability during Zn+ ion (de)intercalation, but also to the coinsertion of H+ and solvation effect of H2O, accelerating the structural decomposition process.

Summary: Heteroatoms doped carbon catalysts show superior ORR activity, stability, and durability compared to Pt/C. The high activity is attributed to the large specific surface area, porous structure, and synergistic effect between different elements, while the stability possibly comes from appropriate graphitization and carbon-coating effect. The synthesis strategy proposed in this study offers advantages of simplicity, low cost, high efficiency, and easy large-scale production for high-performance Fe-N-C electrocatalysts.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
