Ir Nanoparticles Anchored on Metal‐Organic Frameworks for Efficient Overall Water Splitting under pH‐Universal Conditions

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(17)

Опубликована: Март 2, 2023

The construction of high-activity and low-cost electrocatalysts is critical for efficient hydrogen production by water electrolysis. Herein, we developed an advanced electrocatalyst anchoring well-dispersed Ir nanoparticles on nickel metal-organic framework (MOF) Ni-NDC (NDC: 2,6-naphthalenedicarboxylic) nanosheets. Benefiting from the strong synergy between MOF through interfacial Ni-O-Ir bonds, synthesized Ir@Ni-NDC showed exceptional electrocatalytic performance evolution reaction (HER), oxygen (OER) overall splitting in a wide pH range, superior to commercial benchmarks most reported electrocatalysts. Theoretical calculations revealed that charge redistribution bridge induced optimization H2 O, OH* H* adsorption, thus leading accelerated electrochemical kinetics HER OER. This work provides new clue exploit bifunctional pH-universal splitting.

Опубликована: Янв. 3, 2024

Rational modification of the chemical components metal–organic framework (MOF) is one most promising and challenging strategies to alternate noble metals in electrochemical water-splitting field. Multimetallic MOFs have emerged as excellent materials for several applications; however, it remains a significant challenge synthesize characterize these materials. In this work, we report facile approach synthesizing series multimetallic MOF nanosheet-assembled hierarchical flower-like morphologies highly active durable electrocatalysts natural seawater electrolysis. Simultaneously, their three-dimensional nanostructures can provide abundant sites, improve intrinsic catalytic activity, facilitate electron transfer. Consequently, obtained RhCoNi-MOF exhibits overpotentials low 40, 48, 50 mV at 10 mA cm–2 alkaline freshwater, simulated seawater, seawater. also offers an outstanding performance comparable Pt/C. Impressively, two-electrode overall electrolysis device using bifunctional catalyst requires voltage 1.52 V stably maintain over 80 h. The density functional theory calculation reveals that superior electrocatalytic activity be attributed synergistic effects introducing Co Rh metal ions.

Molten Salt Derived MXenes: Synthesis and Applications

Advanced Science, Год журнала: 2024, Номер unknown

Опубликована: Июль 17, 2024

Abstract About one decade after the first report on MXenes, these 2D early transition metal carbides or nitrides have become among best‐performing materials in electrode applications related to electrical energy storage devices and power‐to‐fuels conversion. MXenes are obtained by a top‐down approach starting from appropriate 3D MAX phase that undergoes etching of A‐site metal. Initial procedures based use concentrated HF situ generation this highly corrosive poisonous reagent. Etching is major hurdles limiting progress field. The present review summarizes an alternative, universal, easily scalable procedure treating precursor with Lewis acid molten salt. starts presenting current state art salt obtain modify MXene, followed summary MXene samples. aim show versatility advantages terms general applicability, control surface terminal groups, uniform deposition nanoparticles, other features procedure.
