Novel lanthanum sulfide–decorated zirconia nanohybrid for enhanced electrochemical oxygen evolution reaction

Synthesis of In : SnO2/La4NiS7 via Diethyldithiocarbamate‐Assisted Spin Coating: A Promising Route for High‐Performance Transparent Photoelectrochemical Energy Storage and Generation

“…An overpotential of 263 mV was observed to reach 10 mA ⋅ cm −2 current density [64] . In a study La 2 S 3 nanocrystals‐decorated with ZrO 2 nano‐flakes were investigated for OER reactions having a small over‐potential of 280 mV at 10 mA ⋅ cm −2 current density [65] . In a study nickel sulphide had been conjugated with iron sulphide and embedded on multi‐walled carbon nanotubes in water splitting oxygen evolution reactions.…”

“…[64] In a study La 2 S 3 nanocrystals-decorated with ZrO 2 nano-flakes were investigated for OER reactions having a small over-potential of 280 mV at 10 mA ⋅ cm À 2 current density. [65] In a study nickel sulphide had been conjugated with iron sulphide and embedded on multi-walled carbon nanotubes in water splitting oxygen evolution reactions. A low overpotential of 260 mV was exhibited, which showed enhanced electrochemical performance.…”

Enhancement of Electrocatalytic Oxygen Reduction Reaction and Oxygen Evolution Reaction by Introducing Lanthanum Species in the Carbon Shell

“…Meanwhile, Gu and coworkers proposed the formation of unique covalent bonds between La 2 O 2 CO 3 and carbon could promote the adsorption of active oxygen and the desorption of hydroxide during the ORR process, thus leading to improved reaction kinetics . In addition to rare-earth oxides, some rare-earth sulfides and rare-earth fluorides, such as La 2 S 3 , − YF 3 and LaF 3 , also show great potential in electrocatalytic reactions. Despite the significant advantages of electrocatalysis, poor conductivity makes rare-earth compounds difficult to use for wide applications.…”

Tailored engineering of zinc carbide triggered by N‐enriched carbon nanotubes for prospective water splitting

“…Furthermore, the anodic OER and cathodic HER reactions take longer and are less efficient from a thermodynamic standpoint throughout the entire process of splitting water. Electrolysis can occur at a thermodynamic potential as low as 1.23 V 6,7 . However, because they are endothermic, as well as due to heterojunction resistance and series resistance ( R s ), the process of electrolysis is hindered, and a significant input potential, also referred to as an overpotential, is required 8,9 .…”
