“…The CO 2 formation over CdMoO 4 was reported to come from oxidation of CH 2 O, as the selectivity towards CH 2 O was 100% when the degree of conversion was close to zero [102]. They also performed semiempirical investigations (INDO method) of MeOH interaction with Ga 2 (MoO 4 ) 3 , which they stated had similar performance with respect to MeOH oxidation as Fe 2 (MoO 4 ) 3 [103,104]. Popov et al [105] investigated the effect on selectivity to FA of the excess of MoO 3 on calcium molybdate at 350 • C. At stoichiometric ratios of Mo/Ca = 1.0, the selectivity to FA was 18.5%.…”

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.
