Synthesis of Ordered Carbonaceous Framework with Microporosity from Porphyrin with Ethynyl Groups

Iron porphyrin-derived ordered carbonaceous frameworks

“…S7 and S8, the major products are CO and H2 for all the samples, and only a trace amount of CH4 was detected. While Ni-based OCF synthesized at 600 °C can achieve a good CO2RR catalysis [31], higher annealing temperature of 700 °C provides better electric conductivity [27] which is preferable for superior performance. However, mFeP annealed at 700 °C without ordered structure (Fig.…”

“…Thermally stable metalloporphyrins [28][29][30] are used as a building block, while diacetylene moieties function for the topochemical thermal polymerization to construct rigid three dimensional frameworks, enabling the structure retention upon the pyrolysis. More recently, we have synthesized OCFs also from Ni porphyrin with ethynyl groups as a thermally polymerizable moiety [31]. However, the metal center of the previous OCFs was limited to nickel [27,31].…”

“…More recently, we have synthesized OCFs also from Ni porphyrin with ethynyl groups as a thermally polymerizable moiety [31]. However, the metal center of the previous OCFs was limited to nickel [27,31]. Moreover, the pyrolysis behavior of the ethynyl-incorporated porphyrin remained unclear with no guidance for molecular design.…”

Carbon-rich materials with three-dimensional ordering at the angstrom level

“…For instance, ethynyl group has been found to work as an alternative thermally polymerizable moiety, giving crystalline carbons with developed microporosity. 24…”

Development of Robust Electrocatalysts Comprising Single-atom Sites with Designed Coordination Environments

“…This scarcity of information related to Ni-N-doped carbon materials is likely attributable to Ni-N bonds being more fragile under high-temperature heat treatment conditions than Fe-N and Co-N bonds. 28,29 We therefore used the short heat treatment to synthesize Ni/N-Gr as a CRR electrocatalyst (Fig. 3a).…”
