Hierarchical interfaces engineering-driven of the CoS2/MoS2/Ni3S2/NF electrode for high-efficient and stable oxygen evolution and urea oxidation reactions

Electrocatalytic urea oxidation: advances in mechanistic insights, nanocatalyst design, and applications

“…95 Meanwhile, nanorods, nanotubes, nanoprisms, and nanoowers are also developed in morphological engineering. 7,26,91,128 For instance, NiCo 2 S 4 /C prepared via a straightforward one-pot process shows a hollow cage structure with a diameter of around 500 nm (Fig. 7d).…”

Elaborately tailored NiCo2O4 for highly efficient overall water splitting and urea electrolysis

“…It is worth noting that both of these reactions have inherently sluggish catalytic kinetics. 10,11 Thus, in practical OWS, electrocatalysts with low overpotential and high efficiency are required to minimize the energy loss of the two half-cell reactions. 12 Currently, precious metal-based nanoparticle catalysts, such as platinum (Pt)-based materials for HER and RuO 2 (or IrO 2 ) for OER, are commonly regarded as the benchmark active electrocatalytic materials.…”

Abundant heterointerfaces in CoS2/MoS2 nanosheet array electrocatalysts for the enhanced oxygen evolution reaction

“…37,38 For example, Zhou et al 39 synthesized CoS 2 /MoS 2 @CC through an interface engineering strategy, which exhibited excellent OER performance in alkaline media. Zhang et al 40 demonstrated that the hierarchical interfaces in CoS 2 /MoS 2 /Ni 3 S 2 /NF significantly accelerate the OER and urea oxidation reaction (UOR). Despite the great efforts that have been made so far, the preparation of transition metal sulfides with rich heterogeneous interfaces and active species through controlled and easy-to-manipulate strategies remains a great challenge.…”
