“…According to the transmission electron microscopy (TEM) images, corresponding energy dispersive spectrometer (EDS) results (Figure 3), and relevant literatures, the large size block structure is Mn 3 O 4 . [45] Some MnO x particles with high dispersion and small size are modified on TiO 2 nanosheets successfully. It can be speculated that the Fe 2 O 3 and MnO 2 particles are uniformly distributed on the surface of the TiO 2 nanosheet.…”

A comprehensive study was conducted on the synthesis of FeMnTi monolithic catalysts using plasma electrolytic oxidation (PEO) process combined with hydrothermal method followed by depositing active nanostructures. As synthesized catalysts were characterized using a series of techniques for morphology, structure and surface chemical state investigations. Meanwhile, the CO light‐off curves demonstrate that they possess excellent low‐temperature catalytic performance compared with TiO2 based single transition oxides. Specifically, FeMnTi(0.10, 4) can achieve 100 % conversion at 201 °C, which is due to the homogeneous elements distribution, large surface area and high surface activity. The supersaturation of the deposited solution and deposition time determine the growth of MnOx and the FeMnTi(0.10, 4) has the most suitable Fe/Mn atom ratio of 2.5. Furthermore, the electron transfer between Fe (Fe2+ and Fe3+) and Mn (Mn2+, Mn3+ and Mn4+) ensures the excellent redox properties. The synthetic strategy proposed in this work has general applicability for synthesizing multiple transition oxides monolithic catalysts not only for CO oxidation.

This review systematically evaluates the research and applications of metal mesh‐based catalysts for CO oxidation. CO is a hazardous gas that affects human health and the environment. Traditional cordierite‐based catalysts have drawbacks such as complex preparation, high costs, poor stability, and limited catalytic activity, necessitating exploration of alternative solutions. Monolithic metal mesh‐based catalysts, using metal substrates like Ti, Cu, Fe, FeCrAl, stainless steel, Al and Ni, could address these problems effectively. Generally, each metal mesh requires specific pretreatments to roughen surface and facilitate the loading of active species. Plasma electrolytic oxidation is particularly effective for Ti and Al mesh. This results in a monolithic metal mesh‐based catalyst with uniform surface distribution and fully exposed active species. The review also summarizes in‐situ preparation strategies for metal mesh‐based catalysts and their progress in CO oxidation. Finally, the development potential of metal mesh‐based catalysts is discussed, emphasizing the significant challenges and future prospects for industrial applications.
