Free‐standing flexible films, constructed from two‐dimensional graphitic carbon nitride and titanium carbide (with MXene phase) nanosheets, display outstanding activity and stability in catalyzing the oxygen‐evolution reaction in alkaline aqueous system, which originates from the Ti–N_x motifs acting as electroactive sites, and the hierarchically porous structure with highly hydrophilic surface. With this excellent electrocatalytic ability, comparable to that of the state‐of‐the‐art precious‐/transition‐metal catalysts and superior to that of most free‐standing films reported to date, they are directly used as efficient cathodes in rechargeable zinc–air batteries. Our findings reveal that the rational interaction between different two‐dimensional materials can remarkably promote the oxygen electrochemistry, thus boosting the entire clean energy system.

相互作用的氮化碳和碳化钛纳米片可实现高性能的氧气释放

由二维石墨碳氮化物和碳化钛（具有MXene相）纳米片构成的自支撑柔性膜在催化碱性水体系中的氧气逸出反应中表现出出色的活性和稳定性，而该反应源自Ti–N _x用作电活性位点的基序，以及具有高度亲水性表面的分层多孔结构。凭借这种出色的电催化能力，可与最新的贵金属/过渡金属催化剂相媲美，并优于迄今为止报道的大多数自立式膜，它们可直接用作可充电锌的高效阴极，空气电池。我们的发现表明，不同二维材料之间的合理相互作用可以显着促进氧的电化学反应，从而促进整个清洁能源系统的发展。
