I want to do hydrogen and oxygen evolution reactions using nanoparticles synthesised using laser ablation method. But the yield is very low in this method.
is there a minimal requirement of quantity of the material (nanoparticles in my case) that is needed for the experiment. Like how much of the sample I need to prepare in order to carry out the reactions mentioned above.

You will be implementing a heterogeneous catalytic reaction. The theory is simplified as follows. Molecules of the substance are adsorbed on the surface of the catalyst, activated to reach the activation energy, and then decomposed into hydrogen and oxygen. The ratio of the catalyst and the molecules of the substance can be determined approximately by the number of molecules that completely occupy the area of the catalyst. To do this, you need to know the area of the catalyst taken and the projection of the molecule (water) onto the plane of the catalyst (platinum). The amount of water and platinum can be any and will be determined by the sensitivity of your instruments, with which you fix the amount of hydrogen and oxygen.
