Influence of Metal Species and Content of Fe‐Ni‐Poly(heptazine imides) on their Properties as Electrocatalysts for Zinc‐Air Batteries

Advanced Energy Materials, EarlyView.
Iron/nickel‐modified poly(heptazine imides) are efficient, low‐cost bifunctional electrocatalysts for the oxygen reduction and evolution reactions in aqueous zinc–air batteries. Iron enhances oxygen reduction, while nickel single‐atoms deliver oxygen evolution activity comparable to RuO2.

Cyanamide Derivatives. Part 99. Electrolytic Oxidation of Cyanamide [PDF]

Bulletin of the Chemical Society of Japan, 1976
Abstract Cyanamide was electrochemically oxidized with a platinum anode in aqueous potassium hydroxide. Electrolysis was carried out at 1.30 V vs. SCE of anode potential. Oxidation products consist of several unknown 1,2,3,5-tetrazine compounds and known linear cyano compounds.

Synthesis, Structure, and Eu3+‐Activated Photoluminescence of the Mixed‐Anion Carbodiimide NaLa2F3(CN2)2

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
NaLa2F3(CN2)2 forms via solid‐state metathesis of LaF3 and Na2(CN2) at 550°C and remains stable under ambient air and humidity. The structure is based on [La(NCN)5F4] polyhedra with interstitial Na+; revealing an unconventional red emission when doped with Eu3+.
