In this study, for the first time, carbon paste electrode (CPE) was modified with palladium nanoparticles supported on ethylenediamine-functionalized cellulose (PdNPs@EDAC-CPE), and its performance for electrocatalytic hydrogen production was examined. Field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDX) were used to study the morphology and structure of PdNPs@EDAC, respectively. The electrochemical characterizations were performed using cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS). To optimize conditions, the influence of some parameters including the amounts of PdNPs@EDAC and binder in the electrode composition and the electrolyte type and its pH were examined on the hydrogen production process. Comparison of the proposed electrode with the CPE, CPE modified with functionalized cellulose (EDAC-CPE) and CPE modified with Pd (Pd-CPE) showed that PdNPs@EDAC-CPE has the best performance. The proposed electrode with the very low loaded Pd includes several advantages such as using cellulose as a biodegradable polymer, low cost, very good performance and ease of preparation in a large scale that could be a perfect candidate for high-purity electrocatalytic hydrogen production.

“…53,54 Other combinations using Ni II , Co II , Pb II , Cu II , Mn II , and Zn II as the metal components of Prussian white analogues also exhibit appreciable electrocatalytic activities for hydrogen evolution. 55 Polyoxometalates (POMs) are inorganic cluster species that generally comprise early transition metals such as W, Mo, and V. 56 This class of compounds is the most popular heterometallic electrocatalyst for H 2 evolution because it is easy to integrate different kinds of metal ions into a POM framework. 57 While homometallic POMs are generally unstable in nonacidic solution, several heterometallic POMs can be handled in neutral water, which allows them to be used as building blocks for the preparation of POM-based CPs.…”

Herein, the effects of different types of surfactants including sodium dodecyl sulfate (SDS), cetyltrimethyl ammonium bromide (CTAB), and t‐octyl phenoxy polyethoxy ethanol (Triton X‐100, TX‐100) were presented on the hydrogen evolution reaction (HER) at the surface of carbon paste electrode (CPE) modified with Pd−Cu nanoparticles. Firstly, Cu nanoparticles with average diameters at about 80 nm were electro‐deposited at the CPE surface in H2SO4 solution containing CTAB and CuSO4 by potentiostatic method. Then, Pd−Cu bimetallic nanoparticles with diameters at about 75 nm were prepared through galvanic replacement reaction between PdII ions and Cu particles. The synthesized Cu nanoparticles were covered by CTAB in solution and surface tension of the nanoparticles were decreased, and consequently stabilized. Also, the surfactants play different roles on the HER depending on the electrode polarity and surface charges. The electro‐catalytic activity of the Pd−Cu/CPE and nano‐Cu/CPE towards HER was found to be highest in the presence of SDS. The effects of galvanic replacement reaction and type of surfactants on kinetic parameters of the HER such as cathodic electron transfer coefficient and exchange current density were comparatively investigated.
