Abstract Single atom catalysts have recently received a lot of attention. Here we will introduce our recent results about platinum single atom catalysts used for oxygen reduction reaction, formic acid oxidation, methanol oxidation. The single atom catalyst showed remarkable activity and distinct selectivity from nanoparticle catalysts. We compared Pt nanoparticle or sub-nanometer catalyst with single atom catalyst, and showed the difference in activity, selectivity, and durability. Various supports were used to immobilize Pt single atom, and even full cell was fabricated with Pt single atom catalyst. These single atom catalysts can be very promising to minimize the use of expensive Pt and the undesired side products.
