An organic polymer CuPPc-derived copper oxide as a highly efficient electrocatalyst for water oxidation

Abstract

A novel CuPPc nanoflake material, derived from organic polymers, was used as an excellent water oxidation electrocatalyst for the first time.

Transition Metals‐Based Water Splitting Electrocatalysts on Copper‐Based Substrates: The Integral Role of Morphological Properties

“…For example, Lee et al synthesized CuO nanoflakes derived from CuPPc (copper polymeric phthalocyanine) on copper foam as water oxidation electrocatalyst. [28] The monomer of ionophore, 1,2,4,5-tetracyanobezene and Cu 2 + undergo subsequent high temperature calcination to convert it into CuO. At lower calcination temperature, 400 °C and 450 °C, the surface of the substrate appeared to be still smooth and sparsely embedded with nanoparticles.…”

Facile synthesis of efficient Co3O4 nanostructures using the milky sap of Calotropis procera for oxygen evolution reactions and supercapacitor applications

“…Various electrocatalysts doped with cobalt oxide such as CoO 2 , Co (PO 3 ) 4 , CuCo 3 O 4 , NiCo 3 O 4 , and MnCo 2 O x are reported in the available literature. 35–42 These studies show that these materials are neither stable nor durable under alkaline or acidic conditions. Several methods have been used to synthesize various metal oxides including solvent evaporation, electrochemical, hydrothermal, sol–gel, co-precipitation, and green-mediated approaches.…”

A brush-like Cu2O–CoO core–shell nanoarray: an efficient bifunctional electrocatalyst for overall seawater splitting

“…Moreover, the preparation of electrocatalysts on a Cu foam (CF) substrate has advantages in promoting electron transmission, and the unique 3D structure of CF can quickly eliminate a large number of bubbles generated by the HER and OER. 27,28 Therefore, the preparation of CoO-based hierarchical structural materials on CF is expected to serve as an efficient bifunctional catalyst for alkaline seawater electrolysis.…”
