Green Synthesis of Amorphous Ni–Fe Oxyhydroxide Nanosheets for Oxygen Evolution

ACS Applied Nano Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 24, 2024

Metal oxyhydroxides have been considered efficient electrocatalysts for the oxygen evolution reaction (OER), and structural flexibility has a significant role in boosting catalytic performance. However, control usually requires time-consuming complicated synthesis stages. Here, rapid one-step wet-chemical synthetic approach is reported to construct amorphous NiFeOOH nanosheets (a-NiFex NSs). This short-term, low-cost method can efficiently crystallinity of materials. Interestingly, one regulate defect concentration metal valence by varying Ni/Fe ratio. The high-valence species vacancy structure facilitate nucleophilic attack OH–, activate lattice oxygen, promote electrocatalytic optimized a-NiFe0.86 NS exhibits superior performance with low overpotential 309 mV achieve 100 mA cm–2 high stability. strategy provides facile universal fabricating NiFe-based as highly OER electrocatalysts.

Coordination tuning of FeNi‐HMT Framework derived effective hybrid catalysts for water oxidation

ChemSusChem, Год журнала: 2024, Номер unknown

Опубликована: Окт. 27, 2024

FeNi-based hybrid materials are promising oxygen evolution reaction (OER) catalysts for water electrolysis in hydrogen generation. In this work, the coordination tuning of FeNi-HMT frameworks was achieved by simply changing Fe/Ni ratios using hexamethylenetetramine (HMT) as an organic ligand, and derived FeNi with varied compositions were probed OER. Incorporating varying amounts Fe
