“…Unlike the cases of Fe and Co, Ni-based complexes are generally poor in electrocatalysis for oxygen-reduction reaction. However, specific Ni cyclam complexes 51–54 or Ni-N-modified graphene 55 , which have Ni–N 4 sites, have been reported to show unique electrocatalysis for the CO 2 reduction into CO without significant H 2 evolution and with a high Faradaic efficiency (FE) of ca. 90%.…”

“…Additionally, this selective CO 2 reduction has rarely been reported in carbonaceous Ni/N/C materials made from Ni-based complexes. Figure 6 summarizes the comparison of selective CO 2 reduction activities of Ni 2 -CPD Py 973(1) and three reference materials, characterized by the method reported elsewhere 55 . Ni 2 -CPD Py 973(1) shows apparent CO 2 reduction catalysis into CO (Fig.…”

Despite recent advances in the carbonization of organic crystalline solids like metal-organic frameworks or supramolecular frameworks, it has been challenging to convert crystalline organic solids into ordered carbonaceous frameworks. Herein, we report a route to attaining such ordered frameworks via the carbonization of an organic crystal of a Ni-containing cyclic porphyrin dimer (Ni2-CPDPy). This dimer comprises two Ni–porphyrins linked by two butadiyne (diacetylene) moieties through phenyl groups. The Ni2-CPDPy crystal is thermally converted into a crystalline covalent-organic framework at 581 K and is further converted into ordered carbonaceous frameworks equipped with electrical conductivity by subsequent carbonization at 873–1073 K. In addition, the porphyrin’s Ni–N4 unit is also well retained and embedded in the final framework. The resulting ordered carbonaceous frameworks exhibit an intermediate structure, between organic-based frameworks and carbon materials, with advantageous electrocatalysis. This principle enables the chemical molecular-level structural design of three-dimensional carbonaceous frameworks.

“…Typically, the nonprecious metal‐based carbon materials (such as FeN x /C) have been reported extensively to possess super‐high ORR electrocatalytic activity in both alkaline and acidic conditions . Recently, some N‐and metal (Fe, Mn, Ni)‐codoped carbon materials were also found to be active for CO2RR with high CO selectivity . Herein, we report a cost‐effective carbon material (FeN x /C) as high efficient electrocatalyst bifunctionally for both ORR process and CO2RR process.…”

Herein, a type of Fe, N-codoped carbon electrocatalyst (FeN /C, Fe-N-BCNT#BP) containing bamboo carbon nanotubes and displaying bifunctional high catalytic efficiency for both oxygen reduction reaction (ORR) and carbon dioxide reduction reaction (CO2RR) is reported. It shows high electrocatalytic activity and stability for both the ORR process with onset potential of 1.03 V in alkaline and the CO2RR to CO with high faradic efficiency up to 90% and selectivity of about 100% at low overpotential of 0.49 V. For CO2RR to CO, it is revealed that Fe C is active but the activity of FeN centers is lower than that of C-N-based centers, contrary with that observed for ORR. Due to its low cost and high electrocatalytic performance for these two reduction reactions, the obtained catalyst is very promising for extensive application in future. The revealed huge activity difference of the same types of active sites for different reactions can efficiently guide the synthesis of advanced materials with multifunction.

Atomic scale materials (ASMs) have drawn great interest from researchers in the field of catalysis, due to their novel structures and attractive properties. As a kind of high‐efficiency catalyst, ASMs exhibit massive active sites, fast charge diffusion rates, and maximum atomic utilization, which endow them with a superior catalytic performance. Herein, the current progress in the development of ASMs for core catalytic systems is summarized, which focuses on the distinct structural characteristics and great catalytic advantages of ASMs, as well as their underlying catalytic mechanism for various reactions. Significantly, it is indicated that ASMs are promising catalysts for robust catalysis, which possess high catalytic activity, good selectivity, long‐term stability, excellent poisoning tolerance, and strong conditional adaptability in catalytic applications, and are gradually applied in the field of industrialization. Finally, the opportunities and challenges of ASMs in the field of catalysis are discussed. This review provides a new impetus for the fundamental design and further exploration of catalysts.
