Catalytic conversion of carbon dioxide to methanol using diformate esters as intermediates
The present disclosure relates to a new catalytic process for the production of methanol from carbon dioxide, comprising: (1) the conversion of carbon dioxide and hydrogen to formic acid or formate salts; (2) converting the formic acid or formate salts to diformate esters of diols; (3) hydrogenating the diformate esters to methanol and diols. The diols produced from the hydrogenation reaction can be recovered and re-used to prepare the diformate esters.
CATALYST FOR CONVERTING SYNGAS TO MIXED ALCOHOLS
Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The catalyst has a first component of molybdenum or tungsten, a second component of vanadium, a third component of iron, cobalt, nickel or palladium and optionally a fourth component of a promoter. The first component forms alcohols, while the vanadium and the third component stimulates carbon chain growth to produce higher alcohols.

METHOD OF ALTERING DEGREE OF CURVATURE OF A MOLECULAR CATALYST FOR HIGHER CATALYTIC ACTIVITY
A method of altering degree of curvature of a molecular catalyst for CO.sub.2 reduction reaction (CO.sub.2RR). Briefly, providing a single-walled carbon nanotube (SWCNT). Next, a molecular catalyst having active sites for CO.sub.2RR is provided. The molecular catalyst is dispersed on the SWCNT. A curvature of the active sites of the molecular catalyst is then induced. The alternation of degree of curvature of a molecular catalyst is beneficial for higher catalytic activity in transforming CO.sub.2 into methanol.
