“…As an excellent electrocatalyst, Fe 2.95 (PO 4 ) 2 (OH) 2 thin-film electrode exhibited an overpotential of 281 mV for OER (1 M KOH, 10 mA cm –2 ) and 165.7 mV for HER (1 M H 3 PO 4 , 10 mA cm –2 ), respectively [ 124 ]. As per previous reports, the TM-HP are commonly much more durable than the corresponding TM-phosphates in alkaline electrolytes [ 125 ]. For instance, Mani et al reported orthorhombic iron hydroxy phosphate (Fe 5 (PO 4 ) 4 (OH) 3 ·2H 2 O (FeHP)) synthesized by hydrothermal method from metal chloride precursors and disodium hydrogen phosphate as a source of phosphate ligand precursor (Fig.…”

“…In addition to the quaternary compound, the construction of trimetallic (Co/Ni/Cu) HP NSs on Ni foam has also been published. Zhang et al examined the design of CuHP loaded CoNi hybrid nanostructures by an ion exchanging method [ 125 ]. The excellent OER catalytic activity (a low overpotential of 370 mV at 50 mA cm –2 ) was mainly attributed to the high-valent cobalt species produced in situ during the electrooxidation process.…”

Highlights This review introduces recent advances of various anion-mixed transition metal compounds (e.g., nitrides, halides, phosphides, chalcogenides, (oxy)hydroxides, and borides) for efficient water electrolysis applications in detail. The challenges and future perspectives are proposed and analyzed for the anion-mixed water dissociation catalysts, including polyanion-mixed and metal-free catalyst, progressive synthesis strategies, advanced in situ characterizations, and atomic level structure–activity relationship. Abstract Hydrogen with high energy density and zero carbon emission is widely acknowledged as the most promising candidate toward world's carbon neutrality and future sustainable eco-society. Water-splitting is a constructive technology for unpolluted and high-purity H2 production, and a series of non-precious electrocatalysts have been developed over the past decade. To further improve the catalytic activities, metal doping is always adopted to modulate the 3d-electronic configuration and electron-donating/accepting (e-DA) properties, while for anion doping, the electronegativity variations among different non-metal elements would also bring some potential in the modulations of e-DA and metal valence for tuning the performances. In this review, we summarize the recent developments of the many different anion-mixed transition metal compounds (e.g., nitrides, halides, phosphides, chalcogenides, oxyhydroxides, and borides/borates) for efficient water electrolysis applications. First, we have introduced the general information of water-splitting and the description of anion-mixed electrocatalysts and highlighted their complementary functions of mixed anions. Furthermore, some latest advances of anion-mixed compounds are also categorized for hydrogen and oxygen evolution electrocatalysis. The rationales behind their enhanced electrochemical performances are discussed. Last but not least, the challenges and future perspectives are briefly proposed for the anion-mixed water dissociation catalysts.

In-situ engineering of nonprecious catalysts with highly electrocatalytic performances for H 2 or O 2 generation is one of unresolved challenges in industrial chemistry. In this work, a trimetallic (Cu, Ni, Co) selenide is fabricated in-situ on the nickel−cobalt foam (NCF) modified by the dielectric barrier discharge (DBD) plasma (PNCF) with a facile hydrothermal method. The resulting transitionmetal-based selenide (Cu 3 Se 2 @CoSe 2 −NiSe 2 /PNCF) exhibits excellent catalytic activity for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in 1 M KOH, and the overpotentials stimulated with a current density of 10 (j 10 ) and 100 (j 100 ) mA cm −2 are ∼42 and 178 mV in HER process, as well as 240 and 270 mV in OER. Specifically, the electrocatalytic activity of Cu 3 Se 2 @CoSe 2 − NiSe 2 /PNCF is better than the benchmarked RuO 2 for OER in the high current density region (>j 250 ). In addition, the amount of H 2 and O 2 gases for Cu 3 Se 2 @CoSe 2 −NiSe 2 /PNCF stimulated with j 10 are ∼1.52 and 0.9 mmol h −1 , respectively, thus exhibiting higher efficiency than numerous nonprecious catalysts containing transition metals.

The development and application of trimetallic nanoparticles continues to accelerate rapidly as a result of advances in materials design, synthetic control, and reaction characterization. Following the technological successes of multicomponent materials in automotive exhausts and photovoltaics, synergistic effects are now accessible through the careful preparation of multielement particles, presenting exciting opportunities in the field of catalysis. In this review, we explore the methods currently used in the design, synthesis, analysis, and application of trimetallic nanoparticles across both the experimental and computational realms and provide a critical perspective on the emergent field of trimetallic nanocatalysts. Trimetallic nanoparticles are typically supported on high-surface-area metal oxides for catalytic applications, synthesized via preparative conditions that are comparable to those applied for mono- and bimetallic nanoparticles. However, controlled elemental segregation and subsequent characterization remain challenging because of the heterogeneous nature of the systems. The multielement composition exhibits beneficial synergy for important oxidation, dehydrogenation, and hydrogenation reactions; in some cases, this is realized through higher selectivity, while activity improvements are also observed. However, challenges related to identifying and harnessing influential characteristics for maximum productivity remain. Computation provides support for the experimental endeavors, for example in electrocatalysis, and a clear need is identified for the marriage of simulation, with respect to both combinatorial element screening and optimal reaction design, to experiment in order to maximize productivity from this nascent field. Clear challenges remain with respect to identifying, making, and applying trimetallic catalysts efficiently, but the foundations are now visible, and the outlook is strong for this exciting chemical field.
