“…It has been found that such ladder-like overlapped electronic structure remained stable in the OER process. 102 Moreover, Momeni and co-workers suggested that the dopant of Ce 3+ into NiCo-LDH may change the topological property of the layer and produce more defects, which can improve conductivity and increases the catalytic efficiencies on OER. 52 It should be noted that CeO x layer could also effectively prevent the loss of active species and achieve a highly stable performance.…”

Non-noble metal catalysts are suitable for oxygen evolution reaction (OER) owing to their original oxidation states and oxygen coordination environments, which can regulate the adsorption of OHat the active sites to facilitate the formation of oxygen-containing intermediates. However, the difficulties encountered in the conversion of intermediates (M-OH、M-O、M-OOH) lead to low efficiency. Decorations of transition metal catalysts with foreign elements are regarded as an effective-solving, among which decoration with Ce-based materials (CeBM) is most prominent. This review investigated the current status and future prospects of CeBM-decorated various transition metal electrocatalysts. By presenting a thorough account of the latest development, we aim to set a common ground for the research community to deep understanding the roles of CeBM that are originated from its unique electronic structure and abundant oxygen vacancies. Moreover, we wish to provide own perspectives as how to further the design of Ce-based OER electrocatalysts and where such catalysts may be applied in fields beyond electrocatalysis.

“…[196][197][198][199][200] As witnessed, the doped 2D materials (e.g., graphene, MnO 2 , 2D MOF, MXene, LDHs, TMCs) have been extensively investigated as both the ORR and OER catalysts, while some of them have to be modified to offer bifunctional catalysis. [201][202][203][204][205][206][207][208][209] Implementation of these doped 2D materials enables various promising metal-air batteries to fully exploit the rich surface catalysis. [210][211][212][213] Figure 6f,h, as an example, shows a N-CoSe 2 /3D MXene (Ti 3 C 2 T x ) material used as the cathode of an aqueous Zn-air battery.…”

“…As a family of 2D materials, layered double hydroxides (LDHs), with a formula of [M 2+ 1– X M 3+ x (OH) 2 ] x + (A n – ) x / n · y H 2 O (M is a transition metal, and A is an interlayered anion), are widely studied for their exchangeable anions and tunable interlayer spacing. , Various LDHs such as NiAl-LDH, NiCo-LDH, and NiMn-LDH have been studied for lithium storage. Compared with them, NiFe-LDH is a prospective anode for lithium storage for its special 2D structure, variability in composition, and affluent active sites .…”

Layered doubled hydroxides (LDHs) have aroused much attention in energy storage for their exchangeable anions and tunable interlayer spacing. However, poor electrical conductivity and aggregation of flakes cause huge volume changes and reduce accessible active sites, leading to inferior cycle stability and rate performance. Hence, a NiFe-LDH/Ti3C2 MXene hybrid with uniformly distributed NiFe-LDH nanoflakes decorated on MXene nanosheets through a simple hydrothermal reaction is prepared. Due to the synergism between the Ti3C2 MXene conductive frameworks and NiFe-LDH, NiFe-LDH/ Ti3C2 MXene shows a superior electrochemical property for lithium storage. Its reversible capacity is 898.9 mAh g–1 at 0.1 A g–1, and even at 1 A g–1, it still has 726.1 mAh g–1, without capacity reduction in lithium-ion half-cells. In addition, the corresponding lithium-ion capacitor shows a higher energy density and power density, showing huge application prospect in lithium storage.
