“…The composite catalytic material of cobalt phthalocyanine and carbon nanotubes can produce an excellent catalytic effect. Through in-situ polymerization, composite materials can have more catalytic sites, [78][79] which improves the efficiency of electrocatalytic reaction kinetics and has more optimized catalytic performance. The combination of organic materials and inorganic materials prolongs the catalytic reaction time and broadens the catalytic reaction effect.…”

“…By comparison, it was found that the current density of CoPc2 increased by 25 % compared to CoPc1. It was higher than unsubstituted phthalocyanine [79] and the polymerization of phthalocyanine substituted with tetracyano group around carbon nanotubes. [80] In the long-term electrolysis experiment of 10.5 hours, CoPc2 still maintains its catalytic ability without loss of performance.…”

Fossil energy can bring great convenience to human beings, but the carbon dioxide released at the same time can produce Greenhouse Effect, resulting in the rise of Earth's temperature, which has a great impact on the environment. Therefore, how to efficiently catalyze the reduction of carbon dioxide is a hot issue to be solved. Metal phthalocyanines exhibit superior electrochemical catalytic performance due to their large conjugated structure, while carbon nanotubes and graphene, as nanoscale materials, have extremely large surface area and excellent electrochemical performance. The combination of carbon nanotubes and graphene with metal phthalocyanine can greatly improve the electrocatalytic performance of the composites. Herein, in this review, the mechanism of catalytic reduction of carbon dioxide (CO2) by metal phthalocyanine based composites and its research progress are reviewed, the current problems in the field of electrocatalysis of phthalocyanine based composites with the future prospects are presented. We hope this review will help to stimulate further development of phthalocyanine based composites with high performance CO2 catalytic reduction.

“…Thirdly, since CNTs have a limited length, measures have to be taken to alleviate the problem of contact resistance. This is often done by doping with chemical compounds (chemically or physically) [14,15,16,17,18] or by decoration with metal nanoparticles [19].…”

Despite the widespread use of sonication for individualization of nanomaterials, its destructive nature is rarely acknowledged. In this study, we demonstrated how exposure of the material to a hostile sound wave environment can be limited by the application of another preprocessing step. Single-walled carbon nanotubes (CNTs) were initially ground in a household coffee grinder, which enabled facile deagglomeration thereof. Such a simple approach enabled us to obtain high-quality CNT dispersion at reduced sonication time. Most importantly, electrical conductivity of free-standing films prepared from these dispersion was improved almost fourfold as compared with unground material eventually reaching 1067 ± 34 S/cm. This work presents a new approach as to how electrical properties of nanocarbon ensembles may be enhanced without the application of doping agents, the presence of which is often ephemeral.

Zero or negative emissions of carbon dioxide (CO2) is the need of the times, as inexorable rising and alarming levels of CO2 in the atmosphere lead to global warming and severe climate change. The electrochemical CO2 reduction (eCO2R) to value‐added fuels and chemicals by using renewable electricity provides a cleaner and more sustainable route with economic benefits, in which the key is to develop clean and economical electrocatalysts. Carbon‐based catalyst materials possess desirable properties such as high offset potential for H2 evolution and chemical stability at the negative applied potential. Although it is still challenging to achieve highly efficient carbon‐based catalysts, considerable efforts have been devoted to overcoming the low selectivity, activity, and stability. Here, we summarize and discuss the recent progress in carbon‐based metal‐free catalysts including carbon nanotubes, carbon nanofibers, carbon nanoribbons, graphene, carbon nitride, and diamonds with an emphasis on their activity, product selectivity, and stability. In addition, the key challenges and future potential approaches for efficient eCO2R to low carbon‐based fuels are highlighted. For a good understanding of the whole history of the development of eCO2R, the CO2 reduction reactions, principles, and techniques including the role of electrolytes, electrochemical cell design and evaluation, product selectivity, and structural composition are also discussed. The metal/metal oxides decorated with carbon‐based electrocatalysts are also summarized. We aim to provide insights for further development of carbon‐based metal‐free electrocatalysts for CO2 reduction from the perspective of both fundamental understanding and technological applications in the future.
