Volumetric measurement (water displacement method) of evolved hydrogen gas is the convenient and easily accessible approach. You can carry out the reaction in a small vacuum flask (a conical flask with a side tube), close the flask tightly with a cork and connect the side tube with the open end of water filled inverted burette erected from a water filled trough. When the photocatalytic reaction occurs in the vessel, the evolved hydrogen gas is collected in the burette by downward displacement of water. The volume of gas gives the rough volume of hydrogen evolved. It should be worked out with aqueous tension value at the room temperature to get the exact volume. The exact volume should be converted to corresponding volume at NTP for general use. Have a good time !

Hi Hanieh,
Kindly follow Dr. Kamal opinion, the volumetric measurement (water displacement approach) it's brilliant one!
Cheers!

Hi Hanieh
I'm not sure of the concentration of hydrogen you expect t be evolved or the other gases present but you could consider using a hydrogen leak detector (one that shows concentration rather than just alarms). Example here
