Carbon dioxide the available biological C1 source can be handily hydrogenated into formic acid, the rate of this reduction heavily relies on the pH of the solution.
This outcome is catalysed by ruthenium(II) pre-catalyst complexes with a huge variation of water-soluble phosphine ligands; increased conversions and turnover quantities have been realised.
Carbon Dioxide, which is the co-product of formic acid dehydrogenation, can be entitled to hydrogenate back to formic acid in water or organic solvents on the catalyst texture or in the composure of particular homogenous catalysts.
Vinegar and lemons are incorrect options because they are source of acetic acid.
