The development of a bi-functional active and stable catalyst for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is an important challenge in overall electrochem. water splitting. In this study, firstly, nickel nanocones (NNCs) were formed using electrochem. deposition, and then Ni-Co-Fe based mixed sulfide ultrathin nanosheets were obtained by directly depositing on the surface of the nanocones using the CV method. With a hierarchical structure of Ni-Fe-Co-S nanosheets, not only was a high active surface area created, but also the electron transfer and mass transfer were enhanced. This structure also led to the faster release of hydrogen bubbles from the surface. An overpotential value of 106 mV was required on the surface of this electrode to generate a c.d. of 10 mA cm-2 in the HER, whereas, for the OER, 207 mV overpotential was needed to generate a c.d. of 10 mA cm-2. Furthermore, this electrode required 1.54 V potential to generate a c.d. of 10 mA cm-2 in the total electrochem. water splitting. The resulting electrode also exhibited reasonable electrocatalytic stability, and after 10 h of electrolysis in the overall water splitting reaction, the voltage change was negligible. This study introduces a simple, efficient, reasonable and cost-effective method of creating an effective catalyst for the overall water splitting process. In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Electric Literature of C4H4INO2)
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
