Design and stabilisation of a high area iron molybdate surface for the selective oxidation of methanol to formaldehyde.
The performance of Mo-enriched, bulk ferric molybdate, employed commercially for the industrially important reaction of the selective oxidation of methanol to formaldehyde, is limited by a low surface area, typically 5-8 m(2) g(-1). Recent advances in the understanding of the iron molybdate catalyst have focused on the study of MoOx@Fe2O3 (MoOx shell, Fe2O3 core) systems, where only a few overl...
متن کاملAtmospheric methanol measurement using selective catalytic methanol to formaldehyde conversion
A novel atmospheric methanol measurement technique, employing selective gas-phase catalytic conversion of methanol to formaldehyde followed by detection of the formaldehyde product, has been developed and tested. The effects of temperature, gas flow rate, gas composition, reactor-bed length, and reactor-bed composition on the methanol conversion efficiency of a molybdenum-rich, ironmolybdate ca...
متن کاملOxidation of Methanol using Carburized Molybdenum Catalyst
Molybdenum catalysts carburized in CH4/H2 exhibited activity for methanol electrooxidation (MOR) in half cell measurements. Mo carburized at 773 and 873 K showed high electrooxidation of methanol compared to carburization at other temperatures. Catalyst characterization was carried out by XRD and TPC. The active carbide species responsible to facilitate the MOR was the Mo oxycarbide and –Mo2C s...
متن کاملReflections on Catalytic Selective Oxidation: Opportunities and Challenges
Currently, and looking forward, there is an ever increasing demand to perform chemical transformations with optimized atom and energy efficiency. In parallel, there is also growing interest in diversification of chemical feedstocks from more traditional ones. For example, effective and economic transformation of biorenewable chemical feedstocks and shale-gas, are just two that can be highlighte...
متن کاملAmorphous oxide as a novel efficient catalyst for direct selective oxidation of methanol to dimethoxymethane.
We report for the first time the use of an amorphous oxide catalyst for the selective oxidation of methanol in the gas phase, leading at 553 K to the production of dimethoxymethane with a selectivity as high as 90% at high methanol conversion (68%).
