WebPlatinum helps to accelerate this reaction (acting as a catalyst) by binding with the H2 molecule. When the H2 molecule binds to the platinum surface the bond between the two H's in the H2 is weakened (so that each H can form a weak bond with the Pt surface). Platinum is so good at this that the H2 basically falls apart and forms 2 Pt-H bonds.
