Question

convert carbonmonooxide to methanol

Answer 1

Carbon monooxide can be converted selectively into methanol using Everitt's salt (ES) in the presence of pentacyanoferrate(II) and methanol.
The conversion to methanol can be made sure by mass spectrometer or chromatography. 

Answer 2

Researchers have shown that it is possible to directly convert  CO2 captured from the air into methanol (CH3OH) by using a homogeneous catalyst. A stable catalyst based on the metal ruthenium is used in the process as it does not decompose at high temperatures. With this catalyst and a few other compounds about 79% of the CO2 captured from the air is converted into methanol. In the beginning the methanol is mixed with water. However it is easy to separate it by distillation.
This has two benefits:

1. It removes harmful CO2 from the atmosphere.

2. Methanol can be used as an alternative fuel to gasoline.
