“…At present, the rational design of advanced HER electrocatalysts should consider the two points of the dissociation of water molecules and the H* adsorption energy. Nowadays, the precious metal doping strategy has been widely applied in constructing excellent electrocatalysts in water splitting [ 33 , 34 , 35 ], which can form the optimized catalyst sites with the best free energy profile, thus leading to an ultrahigh mass activity based on precious metals.…”

Water splitting technology is an efficient approach to produce hydrogen (H2) as an energy carrier, which can address the problems of environmental deterioration and energy shortage well, as well as establishment of a clean and sustainable hydrogen economy powered by renewable energy sources due to the green reaction of H2 with O2. The efficiency of H2 production by water splitting technology is intimately related with the reactions on the electrode. Nowadays, the efficient electrocatalysts in water splitting reactions are the precious metal-based materials, i.e., Pt/C, RuO2, and IrO2. Ni (Co, Fe)-based layered double hydroxides (LDH) two-dimensional (2D) materials are the typical non-precious metal-based materials in water splitting with their advantages including low cost, excellent electrocatalytic performance, and simple preparation methods. They exhibit great potential for the substitution of precious metal-based materials. This review summarizes the recent progress of Ni (Co, Fe)-based LDH 2D materials for water splitting, and mainly focuses on discussing and analyzing the different strategies for modifying LDH materials towards high electrocatalytic performance. We also discuss recent achievements, including their electronic structure, electrocatalytic performance, catalytic center, preparation process, and catalytic mechanism. Furthermore, the characterization progress in revealing the electronic structure and catalytic mechanism of LDH is highlighted in this review. Finally, we put forward some future perspectives relating to design and explore advanced LDH catalysts in water splitting.

“…An effective approach for conductivity optimization is metal cation doping, which can introduce a new impurity energy level, lower the band gap, reduce the activation energy barriers, and eventually improve the electron density and efficiency of electron transport. 19 Yang et al demonstrated that doping of W, 20 Cr, 21 and Ru 22 metal cations in NiFe layered double hydroxide (NiFe LDH) could enhance the synergistic interplay among multimetallic matrix centers, optimize the intrinsic conductivity, and improve the OER activity. The Sun group incorporated multivalent vanadium (V 5+ , V 4+ , and V 3+ ) into the NiFe LDH lattice to form the trimetallic NiFeV LDH, which exhibited a much higher catalytic activity than pure NiFe LDH for OER.…”

Developing non-noble metal-based core–shell heterojunction electrocatalysts with high catalytic activity and long-lasting stability is crucial for the oxygen evolution reaction (OER). Here, we prepared novel core–shell Fe,V-NiSe2@NiFe(OH)x heterostructured nanoparticles on hydrophilic-treated carbon paper with high electronic transport and large surface area for accelerating the oxygen evolution rate via high-temperature selenization and electrochemical anodic oxidation procedures. Performance testing shows that Fe,V-NiSe2@NiFe(OH) x possesses the highest performance for OER compared to as-prepared diselenide core-derived heterojunctions, which only require an overpotential of 243 mV at 10 mA cm–2 and a low Tafel slope of 91.6 mV decade–1 under basic conditions. Furthermore, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) confirm the morphology and elementary stabilities of Fe,V-NiSe2@NiFe(OH) x after long-term chronopotentiometric testing. These advantages are largely because of the strong synergistic effect between the Fe,V-NiSe2 core with high conductivity and the amorphous NiFe(OH) x shell with enriched defects and vacancies. This study also presents a general approach to designing and synthesizing more active core–shell heterojunction electrocatalysts for OER.
