Dye‐Mediated Growth of 2D Coppercarbodiimide (CuNCN) Nanostructures and their Metamorphosis into a 3D Cu@C_xN_y Hybrid

Abstract

The concept to translate morphological and structural features from a crystalline precursor into a hybrid material is presented. Cationic organic dyes mediate the formation of loosely interconnected, highly anisotropic CuNCN crystals. Their thermal decomposition affords a macroporous CxNy polymer decorated with copper nanoislands. The hybrid is found to be highly active as hydrogenation catalysts.

Transition‐Metal Carbodiimides as Molecular Negative Electrode Materials for Lithium‐ and Sodium‐Ion Batteries with Excellent Cycling Properties

“…Moreover, plenty of interesting physico‐chemical properties are revealed by comparing metal oxides with the respective carbodiimides (such as those shown in refs. ) and recently, copper and cobalt carbodiimides were applied as non‐oxidic water‐oxidation heterogeneous catalysts, with a dual photochemical and electrocatalytic activity in neutral and basic media . A recent report on the use of carbodiimides in Li‐ion batteries claims that MnNCN is not electrochemically active .…”

“…[26][27][28][29]) and recently,copper and cobalt carbodiimides were applied as non-oxidic wateroxidation heterogeneous catalysts,with adual photochemical and electrocatalytic activity in neutral and basic media. [30,31] A recent report on the use of carbodiimides in Li-ion batteries claims that MnNCN is not electrochemically active. [32] We will show in the following that the latter claim is unfounded.…”

Übergangsmetallcarbodiimide als molekulare negative Elektroden‐ materialien für Li‐ und Na‐Ionenbatterien mit hervorragendem Zyklisierungsverhalten

“…). Kürzlich wurden Kupfer‐ und Cobaltcarbodiimide zum Aufbau nichtoxidischer, heterogener Katalysatoren für die Wasseroxidation eingesetzt, mit zugleich photochemischer und elektrokatalytischer Aktivität in neutralem und basischem Medium . Auch findet man bereits einen Bericht über den Einsatz von Carbodiimiden in Li‐Ionenbatterien, aber ohne elektrochemische Aktivität von MnNCN .…”

Decomposition synthesis of tuneable, macroporous carbon foams from crystalline precursors via in situ templating

“…For the fast, out-of-furnace heating, a heat gun setup as described previously was used. 14 The powders were lled to a quartz tube and directly heated to 430 C under nitrogen ow (0.4 L min À1 ) with a total reaction time of 10 min.…”
