Ce-Doped NiFe-Layered Double Hydroxide Ultrathin Nanosheets/Nanocarbon Hierarchical Nanocomposite as an Efficient Oxygen Evolution Catalyst

Abstract: Developing convenient doping to build highly active oxygen evolution reaction (OER) electrocatalysts is a practical process for solving the energy crisis. Herein, a facile and low-cost in situ self-assembly strategy for preparing a Ce-doped NiFe-LDH nanosheets/nanocarbon (denoted as NiFeCe-LDH/CNT, LDH = layered double hydroxide and CNT = carbon nanotube) hierarchical nanocomposite is established for enhanced OER, in which the novel material provides its overall advantageous structural features, including high… Show more

“…For example, the design and synthesis of LDHs/conducting-material composites can overcome the intrinsically poor conductivity of LDHs and provide a rapid transport of electrons/ions [35][36][37][38][39][40][41][42]. To improve the intrinsic activity, the role of host transition layers and guest interlayer anions in increasing the OER activity have also been considered [43][44][45][46][47][48][49]. Boettcher et al found that the incorporation of Fe shows a more than 30-fold increase in conductivity, as well as a partial-charge transfer activation effect of Fe to Ni sites [50].…”

“…The composite of two or three kinds of non-precious components is an effective approach to enhance the electrocatalytic activity by synergistic effect, and to develop bifunctional catalysts. Nanoarray architectures grown on Ni foam (NF) show excellent electrolytic water performance for their large surface areas, strong conductivity, high stability and efficient electron transfer [18][19][20][21]. For example, NiCo 2 P x @CoNi (OOH) x arrays on NF shows excellent OER performance [22].…”

“…An effective electrocatalyst is a necessity during the OER because it involves a stepwise four‐electron transfer at a high overpotential . To date, noble‐metal‐based materials (e.g., RuO 2 and IrO 2 ) are still considered as being the most efficient electrocatalysts for the OER, but the high‐cost and scarcity make them not the most economically viable options . Therefore, it is of significant importance to develop low‐cost, earth‐abundant, and yet efficient alternatives for the OER.…”

“…[9][10][11][12] To date, noble-metal-based materials (e.g., RuO 2 and IrO 2 ) are still considered as being the most efficient electrocatalysts for the OER, but the highcost and scarcity make them not the most economically viable options. [13][14][15][16][17] Therefore, it is of significant importance to develop low-cost, earth-abundant, and yet efficient alternatives for the OER.A myriad of alternative OER catalysts based on earth-abundant cobalt (Co), including alloys, [18][19][20][21][22] oxides, [23][24][25][26][27] sulfides, [28][29][30][31][32] borates, [33,34] phosphates, [35][36][37][38][39][40] and nitrides, [41][42][43][44] have been widely researched. Among them, the Mott-Schottky hybrids by integrating metal and semiconductor have attracted more attention recently, such as Co/CoN x , [45,46] Co/ CoP x , [47,48] and Co/CoO x , [49,50] owing to the existence of strong coupled interface between different components.…”
