Question

Consider the following reaction mechanism:

1) Initiation
Br2 → 2 Br•

2) Propagation (here a cycle of two steps)
Br• + H₂ → HBr + H•
H• + Br2 → HBr + Br•

3) Termination 2 Br• → Br2

This reaction is catalyzed by platinum.

My question is what does the platinum do? I know that platinum is able to split the H2 bond but is that the only function of the platinum in this reaction?

Answer 1

for the formation of the product we use a Ho-Bra flow battery using platinum as the catalyst for both sides is molecular transport limited with decreases in performance at lower teropera tenes, lower aqueous Hør/8r2 flow rates, and ewhen using Serpentine af rather than interdigitated flow field channels. The decreased performance at bigher membrane thickness also demonstrates ionic transport limitatione . cobile platinum at the boomine electrode increases the performance for both Charge and discbaoge i no mebal Catalyst is needed as it is active for both bromine reduction and evolution a
