The empowered ZAB achieved 1.51 V open-circuit voltage, 88.40 mW cm<sup>\u22122<\/sup> power density and over 1150 h cycle life. Density functional theory analysis indicates that charge transfer from Mo<sub>2<\/sub>C-Fe<sub>3<\/sub>N heterogeneous structure to N-doped biochar can significantly reduce the reaction barrier for oxygen reduction\/evolution reactions, enhancing the adsorption of oxygen intermediates. Cellulose-derived carbon provides a large specific surface area, and N-doping enhances the conductivity of the resultant biochar, which both play a crucial role in the efficient loading of Fe and Mo active sites. This work inspires the design and application of interfacial engineering on low-cost biochar carriers.<\/p>\n<p>Related results were published in Chemical Engineering Journal:<\/p>\n<p style=\"text-align: justify;\">XR Meng, S Gao*, NX Liu, PD Wu, <strong>Zhen Fang*<\/strong>.
