Fabrication of vanadium telluride anchored on carbon nanotubes nanocomposite for overall water splitting

“…Among all, CNTs are best due to their unique dimensionality 34 . On the other hand, CNTs are found to be active supports due to their unique structural characteristics, including electronic conductivity, flexible functional groups, and greater specific surface area, which permit selective interaction with the precursor complex of active component; moreover, CNT production has become an industrial process in current ages 35 . Researchers have developed a wide variety of metal‐Te‐based electrocatalysts, including Na.…”

Dispersed CeOx Nanoflakes on Cu2SiO4 Nanosheets One-Step Deposition on Glassy Carbon for a Robust Energy Conversion System

“…Water splitting electrocatalysis, N 2 reduction, CO 2 reduction, and metal-air devices that can be recharged are the technologies being developed to meet the world’s growing “sustainable energy” needs. − Effective water splitting and various renewable energy conversion technologies involve the construction of active, stable, and earth-abundant electrocatalysts that can perform effectively in the same electrolyte for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). − IrO 2 or RuO 2 are now the most popular electrocatalysts for water splitting during the OER and HER because of their low overpotentials and quick kinetics. , However, these noble-metal-based electrocatalysts are not frequently used because of their scarcity and expensive cost. , Earth-abundant resources and inexpensive materials have been used in several initiatives and advancements toward efficient OER and HER electrocatalysts. − First-row transition-metal compounds have been considered the most intriguing possibilities among the many possible electrocatalysts accessible for water splitting because the electrocatalytic activity may be obtained by regulation of composition, tuning in the structure and tailoring on the surfaces of the material. − First-row transition-metal silicates (TMSs) are proposed as a unique class for potential OER electrocatalysts capable of operating in alkaline media. − The metal cations in the brucite-like layers of silicates could be programed, and the intercalated anions were simple to replace . Hence, inexpensive raw materials, a tunable shape, and an unchanging SiO 4 tetrahedral framework are all advantages of metal silicate. − All of these qualities favor boosting the electrochemical performance of the silicate-based electrode material.…”
