Synthesis of a novel electrocatalyst for hydrogen evolution reaction (HER) is highly demanding for renew-able energy production. This research reports the design and development of novel palladium based metallosurfactant (PdCPC(I)) that belongs to the unique class of inorganic-organic hybrid with striking structural features that are explored for the first time in the HER. The formation of the micelle, molecular orientation and surface characteristics of the metallosurfactant are calculated by conductivity and contact angle measurements. The reduction of palladium in metallomicelles during electrolysis accelerates the HER. Metallosurfactant makes the substrate hydrophilic, which in turn enhances the activity of the modified substrate. The 269 mV and 400 mV (vs RHE) overpotential is required to achieve the 10 mA cm(-2) of current density for PdCPC(I) and CPC, respectively. Tafel slope of PdCPC(I) is 57 mV dec(-1), which signifies that the reaction follows the Volmer- Heyrovsky mechanism in the presence of catalyst. The presence of the palladium in the core of the micelle is certified by ICPMS study. The present electrocatalyst also demonstrates 40 h of electrochemical durability. This work opens the doors toward the enhancement of HER, which fulfills the dreams for future energy resources. (C) 2020 Elsevier Inc. All rights reserved.
