(1.84 V) and IrP4 (1.57 V), high energy is required for these catalysts to proceed the ORR process, thus, these TMP4 catalysts can be abandoned for the ORR. In contrast, the systems with the negative ∆𝐺 𝑂𝐻 * have the relative lower overpotentials. While, for CuP4 catalyst, the strong binding interaction blocks the formation of *OH from *O and brings a higher overpotentials. Furtherly, the values of η ORR for CuP4 (1.61 V), FeP4 (1.09 V), NiP4 (0.87 V), RhP4 (1.16 V), PdP4 (0.54 V), AgP4 (0.92 V), PtP4
