Engineering NiMoO₄/NiFe LDH/rGO multicomponent nanosheets toward enhanced electrocatalytic oxygen evolution reaction

Abstract

Rational hybridization of two-dimensional (2D) nanomaterials with extrinsic species has shown great promise for boosting electrocatalytic oxygen evolution reaction (OER). To date, the rational design and engineering of heterojunctions based...

Electrospun one-dimensional electrocatalysts for boosting electrocatalysis

“…The OER is also a significant half reaction for many important energy conversion technologies, such as metal-air batteries and water electrolysis. [66][67][68] For electrocatalytic water splitting, the OER is commonly considered as the key issue to determine the overall efficiency due to the kinetically sluggish process, which involves a four proton-coupled electron transfer process. [69][70][71] To accelerate the reaction kinetics and improve the OER efficiency, appropriate electrocatalysts should be introduced.…”

Dimension Engineering in Noble‐Metal‐Based Electrocatalysts for Water Splitting

“…Designing and tailoring the dimensions of nanocatalysts will maximize the number of active sites, shorten the ion/electron path to facilitate their transfer rates and enhance the intrinsic activity [31–33] . In addition, dimension engineering may also induce the lattice expansion or shrinkage, which will yield lattice strain and therefore modify the electronic structure [34–36] . Therefore, rationally dimension engineering will endow the noble metal nanocatalysts with distinctive properties, thereby largely promoting their electrocatalytic performance towards water splitting [37,38] …”

“…[31][32][33] In addition, dimension engineering may also induce the lattice expansion or shrinkage, which will yield lattice strain and therefore modify the electronic structure. [34][35][36] Therefore, rationally dimension engineering will endow the noble metal nanocatalysts with distinctive properties, thereby largely promoting their electrocatalytic performance towards water splitting. [37,38] This review aims to summarize the latest achievements of noble-metal-based nanocatalysts in catalytic water splitting (Scheme 1).…”
