“…In an investigation by Inokawa et al [142] was conducted on group 6B elements supported on CeO 2 -ZrO 2 , among those which include MoO 3 , which produced the best selectivity of the investigated samples. A FA selectivity of 60% was found at 50% conversion at 375 • C. This was the best result in the investigated temperature interval of 275-450 • C [142]. Overall, a rather low selectivity was observed.…”

“…In the investigation of group 6b oxides on CeO 2 -ZrO 2 by Inokawa et al [142], WO 3 and Cr 2 O 3 were investigated in the temperature range of 275-450 • C. It was found over the entire range that selectivity and yield was poor, although the conversions were above 60% for both Cr 2 O 3 and WO 3 at 450 • C with the best selectivities being approximately 40% for both Cr 2 O 3 and WO 3 at 275 and 450 • C, respectively [142].…”

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.
