“…26,27 This material, alone, has been used for different applications, such as CO 2 and O 2 reduction. 28,29 Silicon carbide represents a prototypical non-metallic system, on which a graphene overlayer can grow directly, without the need to transfer it from another batch. Graphene on SiC is intrinsically n-doped, 30,31 and its electronic properties can be investigated by photoelectron spectroscopies, such as, for example, the Dirac cone analysis through angleresolved photoemission.…”

“…The characteristic peaks in the FTIR spectra at 731, 756, 780, and 1088 cm −1 in CoPc/FePc HS indicate the presence of β-phase, which is consistent with the conclusion obtained via XRD. The characteristic peak at 911 cm −1 in CoPc/FePc HS belongs to the metal-ligand vibration band, indicating the existence of the M-N 4 macrocycle structure [48][49][50]. The stable M-N 4 macrocycle structure in CoPc/FePc HS is expected to facilitate rapid electron transfer during catalysis [51][52][53].…”

Heterogeneous molecular catalysts, such as metal phthalocyanines, are efficient electrocatalysts for CO 2 reduction reaction (CO 2 RR). However, the rational design and synthesis of a molecular catalyst-based heterostructure for CO 2 RR remains challenging. Herein, we developed a crystalline bimetallic phthalocyanine heterostructure electrocatalyst (CoPc/FePc HS), which achieved an excellent CO 2 -to-CO conversion efficiency (99%) and outstanding long-term stability after 10 h of electrocatalysis. Density functional theory calculations revealed that the enhancement of CO 2 RR performance could be attributed to the distinct electron transfer pattern between FePc and CoPc. The heterostructural engineering in molecular catalysts would inspire a unique approach for improving CO 2 RR performance.

“…Similarly, coated the NiPc/rGO non‐covalent composite on glassy carbon (GC) electrode has been used for electrocatalytic reduction of CO 2 . The results of this research had been shown that the addition of rGO to NiPc increases the catalytic efficiency and electrochemical charge transfer rate of NiPc …”

Biomimetic complexes such as porphyrins, phthalocyanines, and hemins show promising catalytic activities in redox processes. Donor‐acceptor hybrids of these biomimetic macrocyclic complexes with graphene as one of the most critical allotropes of carbon are currently an outstanding scientific frontier. Notably, the composites that consist of these efficient and bio‐inspiring complexes anchored on the surface of the graphene and their widespread applications have gained ever‐increasing interest in the last decade, which expresses their efficiency in practice. Accordingly, this review covers the current status of biomimetic complexes‐graphene composites with particular emphasis on significant signs of their synthesis and characterization also highlighted applications of these composites in academia and industrial redox processes such as oxidation of organic compounds, epoxidation, oxygen reduction reactions, CO2 reduction, and hydrogen evolution reactions.
