“…The application of MMT as support of catalysts has been reported. For example, the catalyst, MoO 3 supported on MMT, exhibited a higher activity in methanol oxidation to formaldehyde, probably due to the fact that impregnation ensures better dispersion of MoO 3 in MMT [18]. Intercalated MMT catalysts with low loaded Pt nanoparticles showed comparable selectivity of the product cinnamyl alcohol at very high conversion in the liquid phase hydrogenation of cinnamaldehyde at different pressures of hydrogen even at room temperature and at moderate pressure [19].…”

A composite support based on nature clay, i.e. montmorillonite (MMT), shows great promise as support materials for Pt electrocatalyst for the methanol oxidation reaction in fuel cell anodes. The reported composite support (CNx-MMT) was prepared via carbonizing MMT which was covered by N-contented polymer. X-ray diffraction and transmission electron microscopy results showed that Pt nanoparticles can be welldispersed on the composite support with highly dispersed tiny crystal Pt nanoparticles. Cyclic voltammetry measurements showed that the Pt/CNx-MMT has the enhanced electrocatalytic activity in methanol oxidation reaction. The developed Pt catalyst supported on new composite support is catalytically more active for methanol electrooxidation than Pt supported on the conventional carbon support and shows good stability, offering promising potential for application of MMT as support for fuel cell electrocatalysis.

A Review and Experimental Revisit of Alternative Catalysts for Selective Oxidation of Methanol to Formaldehyde

et al. 2021

The selective oxidation of methanol to formaldehyde is a growing million-dollar industry, and has been commercial for close to a century. The Formox process, which is the largest production process today, utilizes an iron molybdate catalyst, which is highly selective, but has a short lifetime of 6 months due to volatilization of the active molybdenum oxide. Improvements of the process’s lifetime is, thus, desirable. This paper provides an overview of the efforts reported in the scientific literature to find alternative catalysts for the Formox process and critically assess these alternatives for their industrial potential. The catalysts can be grouped into three main categories: Mo containing, V containing, and those not containing Mo or V. Furthermore, selected interesting catalysts were synthesized, tested for their performance in the title reaction, and the results critically compared with previously published results. Lastly, an outlook on the progress for finding new catalytic materials is provided as well as suggestions for the future focus of Formox catalyst research.

“…Traditionally, most of the research about monolayer dispersion focuses on the systems that consist of molybdenum trioxide dispersed on a support with a high specific surface area. [2][3][4][5][6][7][8][9][10][11] Since the surface structure of the support is usually too complicated to be adequately elucidated, it is hard to observe the diffusing process in a real powder system clearly. Kno ¨zinger's group has already paid attention to the study of the diffusing process and the diffusing mechanism.…”
