Abstract Designing high‐performance palladium (Pd) supports with enhanced ethanol oxidation reaction (EOR) activity has consistently been a challenge. Here, novel anatase titanium dioxide nanosheets‐black phosphorus (ATN‐BP) hybrid is fabricated as support for Pd nanoparticles used in the EOR. The direct ball‐milling of BP nanoflakes and ATN under argon protection lead to formation ATN‐BP hybrids interconnected by cataclastic POTi bonds. structure not only beneficial improving electrolyte...
