“…The structure is that carbon is sp-hybridized and sp 2hybridized, and the sp carbon atoms effectively promote the force between the carbon skeleton and metal atoms, providing additional storage sites. The sp 2 carbon atom maintains π conjugation on the 2D plane, promotes electron migration and effectively increases the electron migration rate, [119] as shown in the Figure 20. The benzene ring are conjugated and linked by a diyne bond to form a two-dimensional planar network structure.…”

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.

A highly active graphdiyne heterojunction with highly efficient photocatalysis is designed and fabricated. This catalyst demonstrates transformative properties on photocatalysis for ammonia synthesis. Such excellent properties are reigned from graphdiyne incorporating Fe site‐specific magnetite resulting in a valence state transition within the catalyst. Our results show the strong advantages of graphdiyne in effectively regulating magnetite activity and coordination environments and also indicate that magnetite can selectively form two different valence tetrahedral coordination Fe and octahedral coordination Fe. The catalysts show remarkable catalytic performance for ammonia synthesis by photocatalysis, indicating transformative photocatalytic activity with an ammonia yield (YNH3 ) of unprecedented level of 1762.35±153.71 μmol h−1 gcat.−1 (the highest YNH3 could reach up to 1916.06 μmol h−1 gcat.−1). This work makes full use of the structural and property features of graphdiyne and opens up a new direction for photocatalysis in the field of catalysis.

“…Graphdiyne as another 2D material similar to graphene, possesses a charge carrier mobility of 2 × 10 5 cm 2 V –1 s –1 and hole mobility of 2 × 10 4 cm 2 V –1 s –1 at room temperature that are comparable to graphene, and also has a strong adsorption ability of CO 2 molecules according to theoretical prediction. [ 162,163 ] Yu's group reported a self‐assembly of graphdiyne nanosheets with TiO 2 nanofibers for photocatalytic CO 2 reduction, the intrinsic topological structure with multiple hybridization states of graphdiyne led to delocalized electrons diffusing from the conjugated 2D network into the unoccupied orbitals of TiO 2 upon contact. Moreover, the graphdiyne/TiO 2 nodes could also act as the hot spots due to the photothermal effect of graphdiyne, which promoted the CO 2 adsorption and activation under light irradiation.…”

As a way to drive chemical reactions by renewable solar energy, photocatalytic technology is an appealing strategy for carbon recycle and value‐added CO2 utilization mimicking the natural photosynthetic system to remedy energy and environmental problems. During the recent decades of exploration, extensive research has been reported on 2D nanomaterials in photocatalytic CO2 reduction because of their unique structural properties. This review highlights the ongoing development of modification strategies for 2D nanomaterials from the viewpoints of defect engineering, surface modification, and hybrid construction, following the sequence of inside‐to‐outside design of the photocatalysts. These methodologies can expand the scope of light absorption, promote the separation of photogenerated charge carriers, and enhance the adsorption and activation of CO2, thus effectively improve the photocatalytic efficiency. The future challenges and opportunities for developing modified 2D photocatalysts are also discussed. It is hoped that this review can provide useful guidelines toward further research on 2D nanocatalysis for CO2 photocatalytic conversion.
