Electronic conduction can accelerate charge transfer, and metal–support interactions help improve the ability to resist CO poisoning, which are important features in methanol oxidation reaction (MOR) catalysis. Thus, an effective support that allows modulation of electronic is highly desired for catalyst construction. Herein, we demonstrate system by coupling Pt nanoparticles (NPs) over N-doped carbon (NC)-modified hollow mesoporous-structured titanium nitride microporous sphere (H-TiN) supports MOR, NC acts as unit regulates indispensable subassembly protecting structures H-TiN; addition, oxophilic properties H-TiN strong interaction between NPs endowed excellent poisoning resistance. The resulting Pt/H-TiN/NC-1.00 exhibited superior MOR activity with a mass 1346 mA mgPt–1, 3.1 times higher than Pt/C catalyst. Moreover, antipoisoning toward comparison catalysts. Our work provides more insights into optimizing modulating direct fuel cells high activity, durability, good tolerance ability.

Hydrogen production via electrocatalytic water splitting is hampered by the slow kinetics of anodic oxygen evolution reaction (OER). To address this limitation, electrochemical hydrogen (HER) can be boosted with more favorable oxidation small organic molecules ideally driven renewable energies, producing valuable chemicals. In context, coupling methanol (MOR) simultaneous formate has garnered significant interest. Such a cost-effective process, meeting growing demand for energy storage and fuel production, requires developing cheap efficient electrocatalysts. Given knowledge gap between precious nonprecious metal electrocatalysts, exemplified nickel its derived compounds, review focuses on MOR from fundamental electrochemistry, materials design synthesis, activity-composition/structure relations. Despite advances, we still face formidable challenges in deciphering intricate catalytic mechanism, elevating activity selectivity to new heights, pioneering development scalable prototypes.
