Transition metal oxides or (oxy)hydroxides have been intensively investigated as promising electrocatalysts for energy and environmental applications. Oxygen in the lattice was reported recently to actively participate in surface reactions. Herein, we report a sacrificial template-directed approach to synthesize Mo-doped NiFe (oxy)hydroxide with modulated oxygen activity as an enhanced electrocatalyst towards oxygen evolution reaction (OER). The obtained MoNiFe (oxy)hydroxide displays a high mass activity of 1910 A/gmetal at the overpotential of 300 mV. The combination of density functional theory calculations and advanced spectroscopy techniques suggests that the Mo dopant upshifts the O 2p band and weakens the metal-oxygen bond of NiFe (oxy)hydroxide, facilitating oxygen vacancy formation and shifting the reaction pathway for OER. Our results provide critical insights into the role of lattice oxygen in determining the activity of (oxy)hydroxides and demonstrate tuning oxygen activity as a promising approach for constructing highly active electrocatalysts.

“…66 Such a high performance and low-cost F-FeCoNi-Ov LDH/NF electrocatalyst can be considered as a prominent candidate for overall water splitting to produce hydrogen gas. Besides, the comparisons of the water oxidation performance between this work and other reports [67][68][69][70][71][72][73][74][75] are listed in Fig. 9d.…”

“…Under the ambitious goals of peaking carbon dioxide emissions and carbon neutrality worldwide, the energy landscape is undergoing a profound shift from reliance on traditional fossil fuels to the pursuit of clean and efficient energy. 1−3 Hydrogen as a clean energy with the highest calorific value of about 1.42 × 10 5 kJ/kg should take responsibility for alleviating the energy crisis and environmental problems; 4,5 however, during the past decades, more than 94% of hydrogen worldwide still comes from the reforming of fossil fuels, which was known as gray hydrogen or blue hydrogen. Although the technical specification and economic performance of this method are commendable, it is not the best choice from the perspective of the environment and resources.…”

Production of renewable hydrogen energy by water electrolysis is an effective method to reduce carbon emissions. In comparison to freshwater, seawater is a more suitable raw material for electrolysis thanks to its abundant reserves. However, the reported catalysts are not suitable for large-scale commercial application as a result of the reduction of catalyst stability and activity within complex natural seawater. To better promote the rational design of electrocatalysts and tackle the challenges of seawater splitting, this mini review summarized recent advances in rational design electrocatalysts for seawater splitting, including constructing a hierarchical structure, decorating a corrosion resistance layer, and introducing a charge redistribution within the system. Afterward, a perspective in the development of large-scale seawater electrolysis for hydrogen production is also proposed.
