Recent advances in transition metal layered double hydroxide based materials as efficient electrocatalysts
The development of efficient electrocatalysts occupies a vital position in achieving efficient energy conversion and storage. Transition-metal-based layered double hydroxides (TM LDHs) featuring unique layered structure have received extensive attention in the field of designing highly cost-effective electrocatalysts. Nevertheless, the practical application of TM LDH-based electrocatalysts still faces a series of challenges including insufficient active sites, inferior intrinsic conductivity and suboptimal robustness. Throughout this review, the most recent researches dedicated to TM LDH-based electrocatalysts are reviewed in terms of structural features, synthetic strategies, modification approaches and electrocatalytic applications. This review focuses on the effective modification approaches and important electrochemical applications of TM LDHs. This review supplies the conducive tools to select the appropriate technics for adequately boosting the electrocatalytic performance of TM LDH-based electrocatalysts and concludes with a salient summary outlining orientations for further research.
