The metal–support interaction offers electronic, compositional, and geometric effects that can enhance the catalytic activity and stability. Herein, a performance‐enhanced electrocatalyst of Pd nanoparticles loaded on a hybrid catalytic support comprised of MXene (Ti3C2Tx) and carbon nanotube (CNT) is demonstrated. Such a hybrid catalyst enhances durability and improves both oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) activities compared with the Pd/C catalysts. The mass specific activity and specific activity of the Pd/Ti3C2Tx–CNT catalyst are 4.4 and 3.3 times that of Pd/C for ORR, respectively. The peak power density of a alkaline anion exchange membrane fuel cell (AAEMFC) based on the Pd/Ti3C2Tx–CNT (1:2) cathode achieves 48 mW cm−2 at 60 °C. Furthermore, Pd/Ti3C2Tx–CNT also exhibits rapid HER kinetics with a low overpotential of 158 mV at 10 mA cm−2 and a Tafel slope of 50 mV dec−1. Pd/Ti3C2Tx–CNT also provides good stability after 1000 cycles. These remarkable catalytic performances are attributed to the role of Ti3C2Tx and CNT by enhancing the catalytic activity surface area and rapid mass/charge transfer due to the synergistic effect between Pd and Ti3C2Tx–CNT.

• The NiFe LDH/Ti3C2Tx-rGO catalyst exhibits 235mV overpotential at 10 mA cm-2, and its Tafel slope is only 40 mV dec-1. • The non-precious hybrid support catalysts exhibit high specific surface area that benefit to the electrochemical activity. • NiFe LDH/Ti3C2Tx-rGO exhibits an extremely stable with only a 6mV potential decreasing after 30000s test. A non-precious metal electrocatalyst for oxygen evolution reaction （OER）is achieved by synergistically coupling layered double hydroxides (LDH) and hybrid supports(reduced graphene oxide (rGO) and Ti 3 C 2 T x -MXene). The NiFe LDH/Ti 3 C 2 T x -rGO catalyst exhibits superior activity with a promising low overpotential of 235 mV at a current density of 10 mA cm−2 in alkaline medium. The strong interfacial interaction and electronic coupling with prominent charge-transfer between the NiFe LDH and Ti 3 C 2 T x is identified, which not only improves the conductivity and stability and of the hybrids, but also greatly accelerates the redox process of NiFe LDH for OER.
