The development of affordable, highly active, and stable trifunctional electrocatalysts is imperative for sustainable energy applications such as overall water splitting rechargeable Zn–air battery. Herein, we report a composite electrocatalyst with RuSe2 CoSe2 hybrid nanoparticles embedded in nitrogen-doped carbon (RuSe2CoSe2/NC) synthesized through carbonization–adsorption–selenylation strategy. This excellent hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR) activities. An in-depth study the effect Se on electrocatalytic process was conducted. Notably, incorporation moderately adjusted electronic structure Ru Co, enhancing all three types catalytic performance (HER, η10 = 31 mV; OER, 248 ORR, E1/2 0.834 V) under alkaline condition accelerated kinetics improved stability.
