2D materials modulating layered double hydroxides for electrocatalytic water splitting

Exploring highly efficient electrochemical water splitting catalysts has recently attracted extensive research interest from both fundamental researches and practical applications. Transition metal-based layered double hydroxides (LDHs) have been proved to be one of the most materials for oxygen evolution reaction (OER), however, still suffered low conductivity sluggish kinetics hydrogen (HER), which largely inhibited overall efficiency. To address this dilemma, enormous approaches including doping regulation, intercalation tuning defect engineering are therefore rationally designed developed. Herein, we focus on recent exciting progress LDHs hybridization with other two-dimensional (2D) reactions, not barely enhancing OER efficiency but also boosting HER activity. Particularly, structural features, morphologies, charge transfer synergistic effects heterostructure/heterointerface that influence electrocatalytic performance discussed in details. The hybrid 2D building blocks only serve as additional supported promote electron at interfaces further enhance performance. construction application nanohybrid will guide a new direction developing multifunctional based LDHs, contribute energy conversion storage.
