Study of the effect of transition metal addition on physicochemical and electrochemical properties of cellulose-nickel phosphide composite
Open Research DataThe oxygen evolution reaction (OER) is a key process in water splitting, enabling the production of clean hydrogen energy. Transition metal phosphides, particularly nickel phosphide (Ni₂P), have garnered attention as potential electrocatalysts for OER due to their high conductivity and catalytic activity. In this study, we present an approach to enhance...
