Pt-1,1′-Bi(2-Naphthol) Nanostructures for Electrochemical H2 Evolution in Alkaline Media

“…Using specific carriers to promote the catalytic performance of metallic nanoparticles (NPs) by engineering their interfaces is an effective strategy. Lately, those with π-conjugated structures have attracted intense interest and significantly impacted the catalysis research area. − Regarding the π-conjugated supports (or carriers), activated carbon and graphitic materials (e.g., graphene oxide and carbon nitride) are the common model materials for HER investigation. They can enhance catalyst reactivity over the active sites and hold the metallic catalyst’s stability, aided by the conjugated electronic effect. , Hybrid nanostructures of inorganic and organic components render them active materials with specialized functions for catalysis, biomedicine, and manufacturing technologies. − Our previous works have discovered that the 1,1′-bi­(2-naphthol) (BINOL) molecule plays a crucial role in controlling the spatial arrangement of Au nanoparticles within Au-BINOL hybrid nanocomposites and their applications for photocatalysis, where BINOL formed nanocarriers through π-stacking and hydrogen bonding. , In this work, we have adjusted the spatial arrangement of Pt NPs in the BINOL hybrid nanocomposite to form concentric nanospheres and lamellar nanoflakes for investigating the Pt-catalyzed HER performance upon the π-conjugated electronic effect from BINOL nanocarriers .…”
