4f–2p–3d Orbital Coupling in Ce–Ni₃S₂ Enhancing the Urea Oxidation Reaction

Inorganic Chemistry, Год журнала: 2024, Номер unknown

Опубликована: Июль 22, 2024

The electrocatalytic urea oxidation reaction (UOR) provides a promising alternative to the oxygen evolution (OER) for various renewable energy-related systems owing its lower thermodynamic barriers. However, optimization and commercial utilization were hampered due lack of mechanistic understanding. Here, we demonstrate Ce-doped Ni

Optimizing NiFe-Modified Graphite for Enhanced Catalytic Performance in Alkaline Water Electrolysis: Influence of Substrate Geometry and Catalyst Loading

Molecules, Год журнала: 2024, Номер 29(19), С. 4755 - 4755

Опубликована: Окт. 8, 2024

The oxygen evolution reaction (OER) and the hydrogen (HER) are critical processes in water splitting, yet achieving efficient performance with minimal overpotential remains a significant challenge. Although NiFe-based catalysts widely studied, their can be further enhanced by optimizing interaction between catalyst substrate. Here, we present detailed investigation of NiFe-modified graphite electrodes, comparing effects compressed expanded substrates on catalytic performance. Our study reveals that substrate geometry plays pivotal role distribution activity, facilitating more effective electron transfer active site utilization. Additionally, observe increasing NiFe loading leads to only modest gains performance, due agglomeration at higher loadings. optimized NiFe-graphite composites exhibit superior stability lower overpotentials current densities, making them promising candidates for sustainable production via alkaline electrolysis.

The climate crisis has become the most serious concern of human beings and environments worldwide in 21st century. Global concerns about cancer epidemiology mainly originate from anthropogenic activities, particularly fossil-based operations. A key solution to this problem is use fuel cells—devices—capable direct conversion chemical energies like urea into electricity. To make their commercialization reasonable, one problems that needs be solved development anodic materials. majority investigations on oxidation are based nickel, but its inadequate activity limits efficiency these devices. In work, we propose synthesize a Ni-Cu-Fe ternary electrocatalyst for through fast facile electrodeposition method. properties synthesized material examined by Scanning Electron Microscopy (SEM) conjugated with Energy Dispersive X-ray Spectroscopy (EDS), Transmission (TEM), Diffraction (XRD). Its electrochemical were also 1 M KOH without 0.15 urea. We found prepared powder active electro-oxidation urea, 1.65 Vvs RHE required current density 10 mA cm−2 stable potential 2.38 3 h polarization at cm−2.
