The uniform dispersion and loading of phthalocyanine molecular catalysts on conductive carbon substrates are crucial for exposing their active sites. significant amount solvent needed to achieve appropriate leads the risk reaggregation during evaporation. Hence, a solventless strategy is adopted by many bypass use solvent. In this study, we showcase deposition transition metal (TMPc) molecules onto self-supporting cloth electrode using an environmentally friendly sublimation technique efficient electrocatalytic CO2 reduction. We meticulously investigated preparation conditions, including heating temperature TMPc type, assess impact reduction activity. as-prepared CC-CoPc-450 demonstrated outstanding comprehensive performance, showcasing remarkable maximum CO Faradaic efficiency (FECO) 97.1% at -0.86 V with current density 8.3 mA cm-2. exhibited excellent stability 16 h long-term eCO2RR process. Density functional theory (DFT) calculations role d-orbitals in TM-N4 synergy π-conjugation electrons facilitating electron transfer process eCO2RR. This study offers fresh perspective eco-friendly TMPcs provides insights into design π-species macrocyclic electrocatalyst electrodes.
