When the Study of the Post-Synthetic Modification Method on a 1D Spin Crossover Coordination Polymer Highlights its Catalytic Activity.

We are interested in studying the catalytic activity of the spin crossover (SCO) complex ([Fe(NHtrz)](NO)). In this work, we demonstrate that, by adapting the experimental conditions, we can switch from a quantitative post-synthetic modification (PSM) reaction to the use of this complex as a catalyst for the formation of imine from 4-amino-1,2,4-triazole. During the catalytic reaction, the iron complex undergoes two different PSM reactions: the first is the action of the aldehyde on the NH groups present on the complex, whereas the second PSM reaction occurs between the imine complex and aminotriazole, leading back to the starting complex.

Iron-Based NASICON-Type Na Fe (PO ) (P O ) Cathode for Zinc-Ion Battery: Zn /Na Co-Intercalation Enabling High Capacity.

The development of high-performance cathode materials for aqueous zinc-ion batteries (ZIBs) based on nontoxic and earth-abundant elements remains a great challenge. This study introduces the iron-based NASICON-type material Na Fe (PO ) (P O7) with carbon layer (NFPP@C) as a cathode material for ZIBs. When Zn /Na dual ion electrolyte is employed, NFPP@C shows a high capacity of 114.
