Abstract Electrocatalytic water splitting is an environmentally benign technique for hydrogen (H2) and oxygen (O2) production. Here, synthesis of Ti3C2@MoO3 nanocomposite by hydrothermal method with improved electrocatalytic activity and stability for overall water splitting is reported. In Ti3C2@MoO3 nanocomposite, Ti3C2 acts as a conductive material to facilitate rapid electron transfer whereas; MoO3 provides long-term stability and prevents Ti3C2 nanosheets from restacking. These combined properties of Ti3C2 nanosheets and MoO3 nanobelts exhibited improved HER and OER performance at a low overpotential of 91 mV and 190 mV at a current density of 10 mAcm−2 with long term durability for 50 h. The strong electronic coupling effect between Ti3C2 MXene and MoO3 nanobelts can accelerate HER/OER kinetics. This study opens new avenues for developing efficient and durable electrocatalytic systems for water splitting.
