Precise adjustment of the metal site structure in single-atom catalysts (SACs) plays a key role in addressing the oxygen evolution reaction (OER). Herein, we report the synthesis of O-doped Ni SACs anchored on porous graphene-like carbon (Ni–O–G) using molten salts (ZnCl2 and NaCl) as templates, in which the unique Ni–O4 structure serves as the active sites. Ni–O–G, with an overpotential of only 238 mV (@ 10 mA cm–2), is one of the more advanced catalysts. An array of characterizations and density functional theory calculations show that the Ni–O4 coordination enables Ni to be closer to the Fermi level compared to traditional Ni–N4, enhancing the electronic metal–support interaction to facilitate OER kinetics. Thus, this work offers an alternative strategy for the structural modulation of Ni SACs and the effect of different coordination elements with the same atomic coordination structure on the intrinsic OER activity.

The world today is witnessing a new technological revolution, particularly in the area of new materials. Different types of materials often have different characteristics and uses. Mesoporous materials have a large specific surface area, easily modifiable inner and outer surfaces, tunable pore size and pore channels, and good biocompatibility and thermodynamic stability, thus emerging as a new candidate material in the chemical research community. The presence of mesopores facilitates the rapid diffusion of macromolecules, reduces resistance to mass transfer, and provides different properties depending on the pore size, making mesoporous materials a potential candidate for a wide range of applications. This paper reviews the recent methods used to synthesize mesoporous materials, including hydrothermal synthesis, microwave synthesis, the sol−gel method, the phase conversion method, and the templating method. The soft templating method is introduced in detail, including bulk self-assembly, solvent evaporation-induced self-assembly, solution-based nanoprecipitation, interfacial self-assembly in a solution, and emulsion template self-assembly. The current status of the processes related to mesoporous materials in the fields of biomedicine, environmental and energy, electrochemical energy storage, and gas separation is elaborated. Finally, the technical issues and future directions in the synthesis and application of mesoporous materials are briefly discussed.

In the 21st century, materials science has developed rapidly. Mesoporous carbon is now among the most attractive substances due to its enormous specific surface area, high porosity, and structured pore structure. There are many methods to synthesize mesoporous carbon, among which the template method is widely used because of the variety of templates and synthesis pathways. Mesoporous carbon has been used in many fields. Its good electrical conductivity, lightweight nature, and low price have led to many applications in electrochemistry, such as capacitors, electrodes, and materials for electric vehicles. This work contains a literature overview on the synthesis methods and modification techniques for mesoporous carbon, as well as its application in electrochemistry, which serves as a guide for the future growth of mesoporous carbon research.
