“…Apart from the above-mentioned composites of Ru metal with other metals, phosphides, and oxides, among others, Ru metal can also be loaded on various functional carbon substrates, generating Ru–C hybrids, which have been extensively reported as extraordinarily high-activity HER electrocatalysts in the pH-universal electrolytes. ,− In these composites, carbon-based supports, including reduced graphene oxide (RGO), carbon nanotubes (CNTs), carbon nanosheet, porous carbon, XC-72 Vulcan carbon, and so on, show many advantages, which are summarized below. ,− First, carbon materials generally have super conductivity, which decreases the electrical resistance among active species . Second, carbon substrates with the ultrahigh specific area can avoid the agglomeration of Ru nanocrystals and accordingly obtain uniform and highly dispersed fine Ru particles .…”

As a highly appealing technology for hydrogen generation, water electrolysis including oxygen evolution reaction (OER) at the anode and hydrogen evolution reaction (HER) at the cathode largely depends on the availability of efficient electrocatalysts. Accordingly, over the past years, much effort has been made to develop various electrocatalysts with superior performance and reduced cost. Among them, ruthenium (Ru)-based materials for OER and HER are very promising because of their prominent catalytic activity, pH-universal application, the cheapest price among the precious metal family, and so on. Herein, recent advances in this hot research field are comprehensively reviewed. A general description about water splitting is presented to understand the reaction mechanism and proposed scaling relations toward activities, and key stability issues for Ru-based materials are further given. Subsequently, various Ru-involving electrocatalysts are introduced and classified into different groups for improving or optimizing electrocatalytic properties, with a special focus on several significant bifunctional electrocatalysts along with a simulated water electrolyzer. Finally, a perspective on the existing challenges and future progress of Ru-based catalysts toward OER and HER is provided. The main aim here is to shed some light on the design and construction of emerging catalysts for energy storage and conversion technologies.

“…Water electrocatalysis has two half-reactions, producing H 2 at the cathode component by the hydrogen evolution reaction (HER) and producing oxygen at the anode by the oxygen evolution reaction (OER) [10,11]. The produced H 2 is used as a fuel and blended into the atmosphere with O 2 .…”

“…The produced H 2 is used as a fuel and blended into the atmosphere with O 2 . Currently, Pt, Au, Ru, and Pd-based catalyst has been working as a superior HER process, but it has some flaws, such as high cost and the minimum amount of H 2 output [6,7,[10][11][12]. Therefore, alternative water electrolysis materials must be produced with an economical and effective catalyst relative to the aforementioned HER catalyst.…”

A glassy carbon electrode (GCE) coated with delafossite CuCrO2 loading on the nitrogen-doped reduced graphene oxide (N-rGO) and multiwalled carbon nanotubes (MWCNT) composite (N-rGO-MWCNT/CuCrO2) was applied to the hydrogen evolution reaction and Bisphenol-A (BPA) detection. First, the N-rGO-MWCNT composite was prepared by in situ chemical reduction with caffeic acid as a reducing agent. Then, CuCrO2 was accumulated on the N-rGO-MWCNT surface to form N-rGO-MWCNT/CuCrO2 composite. The morphology structure of the N-rGO-MWCNT/ CuCrO2 composite was analyzed by different characterization techniques. Besides, the GCE/N-rGO-MWCNT/CuCrO2 composite electrode was investigated for hydrogen evolution reaction (HER), which shows an excellent electrocatalytic activity with a low over-potential, increasing reduction current, and a small Tafel slope of 62 mV·dec−1 at 10 mA·cm−2 with long-term stability. Moreover, the electrochemical determination of BPA was in the range of 0.1-110 µM, and low detection limit of 0.033 µM (S/N = 3) with a higher sensitivity of 1.3726 µA µM−1 cm−2. Furthermore, the prepared GCE/N-rGO-MWCNT/CuCrO2 electrode shows effective detection of BPA in food samples with acceptable recoveries. Hence, the finding of GCE/N-rGO-MWCNT/CuCrO2 can be observed as an impressive catalyst to the electrocatalytic activity of HER and BPA oxidation.
