MXene‐based material has attracted wide attention due to its tunable band gap, high conductivity and impressive optical and plasmonic properties. Herein, a hetero‐nanostructured water splitting system was developed based on N‐doped Ti 3 C 2 (N 10 TC) MXene and NiFe layered double hydroxide (LDH) nanosheets. The oxygen evolution reaction performance of the NiFe‐LDH significantly enhanced to approximately 8.8‐fold after incorporation of N 10 TC. Meanwhile, the Tafel slope was only 58.1 mV dec −1 with light irradiation, which is lower than pure NiFe‐LDH nanosheets (76.9 mV dec −1 ). All results manifested the vital role of the N 10 TC MXene induced plasmonic hot carriers via electrophoto‐excitation in enhancing the full water splitting performance of the as‐prepared system. This work is expected to provide a platform for designing various plasmonic MXenes‐based heterogeneous structures for highly efficient catalytic applications.
