“…XPS was used to analyze the surface electronic properties of Pt, and the Pt 4 f spectra are shown in Figure 4. There were two pairs of doublets, with the more intense doublet (71.34 eV and 74.65 eV) belonging to metallic Pt 0 and the other doublet (72.65 eV and 75.81 eV) corresponding to the Pt 2+ chemical state [35] . Metallic Pt 0 comprised the majority of all the Pt content, and the existence of Pt 2+ indicated that some Pt atoms were oxidized in the air.…”

Using microwave irradiation, PtCo alloy nanoparticles were deposited within a few minutes on COOH‐functionalized MWCNT supports. The obtained catalysts were used for selective hydrogenation of cinnamaldehyde, a reaction whose products are widely used in various fields. In the selective cinnamaldehyde hydrogenation to cinnamyl alcohol, microwave‐prepared catalysts (generically, PtxCoy‐MW) outperformed a catalyst prepared by the conventional method (Pt1Co2‐con). The highest selective hydrogenation to cinnamyl alcohol, 89%, was obtained using Pt1Co2‐MW, while Pt1Co2‐con showed a selectivity of 76%. Characterization results confirmed that the microwave prepared samples had a stronger interaction between Pt and Co than that in the Pt1Co2‐con sample. The alloyed Co altered the electronic structure of Pt, leading to favorable adsorption of the C=O bond by the lone‐pair electrons of its oxygen atom. Moreover, the Pt1Co2‐MW sample showed neglectable change in catalytic performance (e. g., cinnamaldehyde conversion and selective hydrogenation to cinnamyl alcohol) during recycling experiments.

“…Researchers had used Pt−Sn/C for MOR for a longer period of time [63] . The PtSn electrocatalyst activity for MOR varies significantly with the molar ratio of PtSn, the carrier structure, and its synthesis method [64] .…”

“…The PtSn electrocatalyst activity for MOR varies significantly with the molar ratio of PtSn, the carrier structure, and its synthesis method [64] . Currently, carrier materials are used for PtSn catalysts including carbon sulfide, [63] carbon nanotubes, [66] carbon fiber [67] and so on. At the same time, a higher degree of catalyst dispersion on suitable support can reduce the Pt's amount used in the active layer without the absence of loss performance, and dispersing the material in a suitable electron‐conducting mold can obtain better catalytic particles dispersion and it offered efficient transport of charge from the electrode carrier to the reaction site.…”

The methanol oxidation reaction has high energy density and the product is non-toxic and harmless (CO 2 , H 2 O), making it become one of the targets of new fuel energy. To maximize the efficiency of the reaction, its key lies in the development of highly efficient catalysts. In this paper, we reviewed the types of methanol electrocatalytic oxidation catalysts in recent years, some new preparation methods, and the reaction mechanism of different types of catalyst systems, and discussed their structure-activity relationships, laying the foundation for the development of highly efficient new catalysts in the future. And this paper is included on the types of catalysts (Pt-based catalyst, Ni-based catalyst, and other transition metal-based catalyst) and preparation methods (Reduction method, sol-gel method, in-situ method), and discussed the catalytic mechanism which mainly starts from two aspects, one is adsorptiondesorption, the other is the bond between the catalyst, methanol, and the medium. Finally, the future challenges and opportunities of the electrocatalytic oxidation of methanol are discussed.
