摘要：

The intrinsic roadblocks for designing promising Pt-based oxygen reduction reaction (ORR) catalysts emanate from the strong scaling relationship and activity-stability-cost trade-offs. Here, a carbon-supported Pt nanoparticle and a Mn single atom (Pt(NP)-Mn(SA)/C) as in situ constructed Pt(NP)-Mn(SA) pairs are demonstrated to be an efficient catalyst to circumvent the above seesaws with only ∼4 wt % Pt loadings. Experimental and theoretical investigations suggest that Mn(SA) functions not only as the "assist" for Pt sites to cooperatively faci...
