The development of advanced Pt-alternative anode electrocatalysts with high activity and reliable stability is critical to overcoming the technical challenges direct methanol fuel cells. Here, we propose a robust bottom-up strategy for spatial construction mesoporous hollow carbon sphere (HCS)-embedded MXene architectures decorated ultrafine Rh nanocrystals (Rh/HCS-MX) via stereoscopic coassembly reactions. rational intercalation HCS effectively separates nanowalls achieve rapid mass-transfer efficiency, while intimate coupling hybrid carrier enables their electronic structure optimization, thus contributing strong synergistic catalytic effects. Accordingly, resulting Rh/HCS-MX exhibit outstanding electrooxidation properties in terms large electrochemical active surface areas, mass/specific activities, good long-term stability, all which are significantly superior traditional Rh/carbon black, Rh/HCS, Rh/MXene as well commercial Pt/carbon balck Pd/carbon electrocatalysts.
