Neutron scattering methods observed complete room temperature conversion of methanol to framework methoxy in a commercial sample of methanol-to-hydrocarbons (MTH) catalyst H-ZSM-5, evidenced by methanol immobility and vibrational spectra matched by ab initio calculations. No methoxylation was observed in a commercial HY sample, attributed to the dealumination involved in high silica HY synthesis.

Clean methanol can play an important role in achieving net zero emission targets by decarbonizing the energy and chemical sectors. Conventionally, is produced using fossil fuel as raw material, which releases a significant amount of greenhouse gases (GHGs) into environment. methanol, hydrogen (H2) from renewable sources (green H2) captured carbon dioxide (CO2), totally free influence fuel. Due ...

For decades it has been debated whether the conversion of synthesis gas to methanol over copper catalysts is sensitive or insensitive to the structure of the copper surface. Here we have systematically investigated the effect of the copper particle size in the range where changes in surface structure occur, that is, below 10 nm, for catalysts with and without zinc promotor at industrially relev...

Most kinetic studies of methanol synthesis over Cu/ZnO catalysts have been carried out using mixtures of carbon monoxide and hydrogen. But in some cases (1) the synthesis gas has also contained carbon dioxide (2). Power rate laws as well as complicated rate expressions have been proposed over the years. The detailed kinetics of the surface processes is virtually unknown. With the exception, per...

We present here the first example of direct synthesis polyureas from dehydrogenative coupling diamines and methanol.

The reaction pathways connecting methanol to methane and formaldehyde are among the most emblematic in chemistry because of their outstanding interest in the fields of energy, synthesis, and bio- and geo-chemistry. Despite of its fundamental nature, the one-pot synthesis of formaldehyde and methane stemming from methanol has never been reported before. Here we present a study, based on ab initi...
