Metal-free carbon electrocatalysts have attracted significant attention due to their low cost and structural diversity. However, their advancement in 2e^- ORR has been severely hampered by the inefficient bulk production of H₂O₂. In this study, we report a dual-engineering strategy for enhancing H₂O₂ electroproduction by constructing a sulfur and oxygen (S, O) co-doped defective carbon electrocatalyst (HP-ACB). This HP-ACB electrocatalyst achieves a remarkable H₂O₂ kinetic current density of 184.3 A g^-1, a high Faradaic efficiency of 94 %, and enhanced H₂O₂ production reaching 8.21 mol g_cat^-1 h^-1. Experimental results with theoretical calculations demonstrate that the excellent electrocatalytic performance of HP-ACB in 2e^- ORR is attributed to the introduction of S, O atoms and defective carbon, which synergistically reduce the overpotential required for the adsorption of the key intermediate (OOH^⁎) on catalyst surface in 2e^- ORR.

However, conventional single-mode electric fields (AC or DC) exhibit inherent \"orientation-distribution\" contradiction. Specifically, AC fields are effective for orientation but lack spatial control, while DC fields promote filler enrichment but fail to optimize orientation state. This study presents an innovative approach by establishing a theoretical framework that integrates both AC and DC electric fields along with a corresponding microscale dynamic model. This approach enables the precise and flexible manipulation of complex filler arrangements, thereby expanding opportunities for advanced material design. The model refines classical dielectrophoresis theory, incorporating interfacial charge and local electric field effects, elucidating the dynamic mechanisms of fillers under combined AC-DC electric fields. Numerical simulations reveal that AC fields primarily control orientation through dielectrophoresis, while DC fields regulate spatial distribution via electrophoresis. The synergistic combination of these two electric fields yields a pronounced \"orientation-enrichment\" effect, enabling the controlled and orderly arrangement of fillers within targeted areas. Moreover, high-aspect-ratio fillers promote chain formation but restrict rotation and migration, and frequencies above 1 kHz suppress alignment and interparticle attraction. Preliminary material design and preparation for enhanced electrical properties of renewable energy transmission device further indicate that this method is effective and flexible for complex application scenarios.
