The Structure Sensitivity of HxMoO3 Precipitation on MoO3(010)during Reactions with Methanol
Atomic force microscopy has been used to examine the effect of surface morphology on the formation of HxMoO3 during the reaction of MoO3 with methanol. By heating MoO3 crystals in hydrous environments, pits can be formed on the (010) surface. We have found that pit formation is activated by elastic strain from extended defects and because of this, it is possible to exercise some degree of contr...
متن کاملMethanol electro-oxidation on platinum modified tungsten carbides in direct methanol fuel cells: a DFT study.
In exploration of low-cost electrocatalysts for direct methanol fuel cells (DMFCs), Pt modified tungsten carbide (WC) materials are found to be great potential candidates for decreasing Pt usage whilst exhibiting satisfactory reactivity. In this work, the mechanisms, onset potentials and activity for electrooxidation of methanol were studied on a series of Pt-modified WC catalysts where the bar...
متن کاملThe Partial Oxidation of Methanol by Mo03(010) Surfaces with Controlled Defect Distributions
Atomic force microscopy has been used to determine how M0O3(010) surfaces with controlled defect populations evolve during reactions with MeOH/N2 mixtures. The structural evolution of the freshly cleaved surface is compared to surfaces reduced in 10%H 2/N2 at 400 *C. While the freshly cleaved surfaces are flat and nearly ideal, the reduced surfaces contain voids bounded by step loops where Mo a...
متن کاملThe Morphological Evolution of the MoO3(010) Surface during Reactions in Methanol–Air Mixtures
Atomic force microscopy has been used to characterize the evolution of MoO3(010) growth and cleavage surfaces during reactions with air–N2–MeOH mixtures between 200 and 300◦C. At reaction temperatures ≥250◦C, closed step loops, bounded by undercoordinated surface Mo sites, nucleate and grow as the (010) surface volatilizes in a nearly layer-by-layer fashion. The density and crystallography of t...
متن کاملReactivity of Sulfur Molecules on MoO3 (010) Surface.
Two-dimensional and layered MoS2 is a promising candidate for next-generation electric devices due to its unique electronic, optical, and chemical properties. Chemical vapor deposition (CVD) is the most effective way to synthesize MoS2 monolayer on a target substrate. During CVD synthesis, sulfidation of MoO3 surface is a critical reaction step, which converts MoO3 to MoS2. However, initial rea...
