Carbon-based materials that act as supports to design electrocatalysts have been actively pursued for fuel cells and overall water-splitting (OWS) applications. However, carbon-based face serious carbon corrosion at high positive potentials, affecting catalyst activity stability hindering practical applicability. Herein, carbon-free transition metal-oxide–based 2D titanate nanosheet support has proposed, demonstrating the applicability of nanosheets an alternative designing electrocatalysts. A new chemical route produce large via exfoliation discovered. Colloidal allows growth active nickel molybdenum oxide (NiMoOx) forming Titanate@NiMoOx core–shell materials. Fine heat treatment different temperatures facilitates in situ formation MoOx NiMoOx layers on boosting catalytic activity. An increase semiconductivity phase a simultaneous decay component, resulting poor The optimal Titanate@NiMoOx_200 required overpotential 0.54 1.19 VRHE HER OER cell voltage 1.75 V deliver current density 10 mA cm–2 with spectacular up 24 h KOH media. Spectroscopic microscopy analyses prove efficient electronic interaction between hybrid components. Density functional theory experimental work suggest MoOx/NiMoOx shows higher water adsorption energy excellent performance. This sheds light feasibility application rational diverse from noble non-noble metal-based range electrochemical
