Shahid,  it is possible to produce hydrogen from the reaction of formic acid.  What others are trying to tell you that OXIDATION of formic acid would yield CO2 and 2H+.  The production of H2 has to come from the reduction of the 2H+, not the oxidation of formic acid.

I collect the produced gas in an upside down bottle filled with water and immersed in water too. The water acts as the sealer and the bottle is graded to see volume of produced gas. Then, to quantify the H2 I do gas cromatography.

How much do you anticipate making in your reaction?  The best technique depends on the amount.

How can H2 be formed in oxidation of formic acid? CO2 is the expected product

HC(O)OH - 2e(-) -> CO2 + 2 H(+)

Agree with Veronica and Prof. Yurii Sir's  views. You can follow as Veronica and also look into the matter of CO2.

Agree with Yurii Geletii: there are no hydrogen produced during FA electrooxidation on Pd catalysts.

hydrogen is produced in this manner,''Clean hydrogen generation through the electrocatalytic oxidation of formic acid in a Proton Exchange Membrane Electrolysis Cell (PEMEC)''

Dear Shahid,

Have you read this paper?  Look at Fig 1, the right panel. CO2 is the product of formic acid oxidation.

I am surprised the paper was published with the given title since it really does not fully describe the process.  As many have said, hydrogen is not truly the product of formic acid oxidation, it is the product of proton reduction.  So, yes, if you use formic acid, you can set up a favorable cell compared to that required for water splitting.  However, you then have the problem of CO2 formation and the carbon footprint is not as favorable.

Dera Yurii V Geletii and Joseph S Merola,

thanks for your kind suggestions but we are considering the Hydrogen produced in the formic acid oxidation irrespective of CO2 because CO2 is not poisonous to our system.

Dear Shahid,

If you want online realtime in-situ measurements of H2 (and/or CO2) or any other gaseous species formed, you could use a atmospheric gas analysis system such as that from Hiden Analytical (http://www.hidenanalytical.com/en/products/for-gas-analysis/qga-atmospheric-gas-analysis-system). There is also the option of DEMS (differential electrochemistry mass spectrometry) which may also be of interest to you.

I hope this helps

Thanks Steven Fiddy for your valuable suggestion.

Dear Shahid,

"we are considering the Hydrogen produced in the formic acid oxidation"

Please, write this revolutionary reaction.

Sir Yurii V Geletii,

here is some reference links for the current problem.

Please, please, please, read the papers before referring

Do you understand the difference between yours:

" the Hydrogen produced in the formic acid oxidation"

and the title of the JACS paper:

"Iron-Catalyzed Hydrogen Production from Formic Acid"

or Nature

Hydrogen production from formic acid decomposition at room temperature using a Ag–Pd core–shell nanocatalyst

By DEFINITION hydrogen can't be formed in the reaction of formic acid oxidation

sir Yurii V Geletii,

I just steped in the research field and cant even discuss with scientist like you.. but I want to clear myself that if hydrogen is not produced in this reaction then why I get current in the cyclic voltametric measurments... from where this current originates. I got totally confused about the situation.

Shahid,  it is possible to produce hydrogen from the reaction of formic acid.  What others are trying to tell you that OXIDATION of formic acid would yield CO2 and 2H+.  The production of H2 has to come from the reduction of the 2H+, not the oxidation of formic acid.

yes sir I got it. thanks for the kindness
