Enhanced electrocatalytic hydrogen evolutions of Co(II)phthalocyanine through axially coordinated pyridine-pyrene

Non-precious metal catalysts can effectively evolve hydrogen in aqueous media, but a highly efficient metal-based catalyst is still a significant assignment. Herein, Co(II)phthalocyanine was noncovalently immobilized on multiwalled carbon nanotubes through axial coordination via pyridine-pyrene linker and applied towards hydrogen evolution reactions. This material provided a superiorly enhanced electrocatalyzed performance signifying high efficiency. With this behaviour, our target material we believe paves the way towards designing efficient energy production and storage devices.
