A high-performance reduced graphene oxide/ZnCo layered double hydroxide electrocatalyst for efficient water oxidation

Abstract: Tailoring high performance, stable, and earth-abundant electrocatalysts for water oxidation is of fundamental importance for the development of promising energy conversion and storage technologies. In this work, we report a remarkably simple and efficient approach for the preparation of ZnCo-layered double hydroxides and reduced graphene oxide (RGO/ZnCo-LDH) nanocomposites via a facile one-pot coprecipitation method. The resulting RGO/ZnCo-LDH complex investigated for the first time as a catalyst for oxygen ev… Show more

“…The assembly process was monitored by UV-vis spectra ( periodic layered structure of UTFs. S5) for (CoNi-LDH/Fe-PP) 10 UTF shows that Co, Ni, Fe and O are homogeneously distributed throughout the film with Co/Ni/Fe ratio of 4/2/1 (Table S1), consistent with the XPS results (Fig. Moreover, the crystallographic thickness of an exfoliated CoNi-LDH nanosheet is determined to be ~0.57 nm by AFM (Fig.…”

“…[6][7][8][9][10] Layered double hydroxides (LDHs) are a family of anionic layered materials, which consist of brucite-like [Mg(OH) 2 ] host sheets with edge-sharing metal-O 6 octahedra. To address these issues, increasing efforts have been focused on the high-efficiency and earth-abundant alternatives, such as first-row transition metal oxides/hydroxides and perovskites.…”

“…Apparently, the CoCr LDH with Co/Cr ratio of 2:1 still exhibits the best OER activity. To our best knowledge, the OER activity of the CoCr LDH is better than or comparable with the previous reported Co-based LDH (ZnCo LDH 33 , ZnCo LDH/rGO 35 Figure 6f and Table S2. Moreover, the CoCr LDH nanosheets also exhibit better durability in 0.1 M KOH solution compared with RuO2.…”

“…LDHs have been widely studied in the field of catalysis and adsorption for their unique structure, morphology and versatile composition [29][30][31][32][33]. Recently transition metalcontaining LDHs have attracted increasing interest for their potential application in electro-catalysis [34][35][36][37][38][39]. LDHs, such as NiFe-LDHs [34][35][36]39], CoMn-LDHs [37] and ZnCo-LDHs [38], have been studied as electro-catalysts for oxygen evolution reaction (OER).…”

Although calcinated CoFe-LDHs [40] and Co-Fe oxides [41] synthesized by solvothermal route have been used as ORR catalysts, original LDHs have seldom been explored as ORR catalysts.…”
