Does Phosphate Buffer Suit All Catalysts in Water Splitting Experiments?

[QUOTE="Jr_Particle_Hunters, post: 5914936, member: 614266"] Hi there. We are working on a school science project to compare how different catalysts in water splitting affect the energy/voltage needed to carry out the process. One of our catalysts will be Co-Pi, which is created by adding Cobalt-nitrate to a .1M phosphate buffer solution during electrolysis. (The Co-Pi catalyst takes the form of a brownish-green layer that plates the electrode.) For the sake of controlling our variables, if we use Nickel-nitrate as another catalyst (and other metal catalysts as well), can we still use the phosphate buffer solution? In other words, will the phosphate buffer solution work for lots of different kinds of catalysts, or do some materials require a different solution? Also, we are not sure if our experiment should include measuring the amount of O2 gas produced. Since two H20 molecules ----> two H2's and one O2, can we just safely assume that every catalyst will produce an amount of H2 and O2 gas that is always proportional to the amount of voltage utilized? Thanks! [/QUOTE]
