Solar to hydrogen ratio (STH)
= [{(mmol H2/s) X (237 KJ/mol)}/{total power (mW) in the expose area}]AM 1.5 G
Now my query is
If we use different amount of catalyst in same reaction condition the generation of hydrogen will be vary and it will give different value of STH
How we can normalize this problem?
Or I have misunderstood some points…..
STH is directly related to the quantum yield. The quantum yield depends on numerous factors including the catalyst concentration. A catalyst might be involved in photochemical reactions as well as in "dark" reactions. Whatever normalization does not make any sense if you do not understand how the catalyst works.
Dear Prof. Geletii,
Thank you for your answer
If possible, could you please discus the point a little more in details....
If you allow me I would like to write a mail to you in details regarding my problems on STH calculation.
