About Paper:

Metal-organic frameworks (MOF) offer promising solutions for clean energy resources due to their photoactivity and ability to catalyze water- splitting reactions (WOR). MOFs can be implemented into photoelectrochemical (PEC) cells and manipulated for hydrogen fuel production. Primarily, those containing earth-abundant materials Fe, Ti, etc. are the most interesting for creating effective and economic energy production. Previous research has shown promising results for Fe-based MOFs such as MIL-126 and MIL-124 decorated with Ru-containing catalysts, Fe-triazolate (Fe(ta)2), but combined Ti and Fe MOFs have yet to be characterized for their catalytic and photoanode properties, particularly FeMIL-125-NH2. Building on the growing need for clean energy production, the characterization of MOF FeMIL-125-NH2 in a PEC cell is achieved. In acidic and neutral environments, 24-hour chronoamperometry is taken with periodic irradiation of the photoanode to observe oxygen and hydrogen production. Raman spectroscopy is used to investigate structural transitions in the MOF under test conditions. By investigating FeMIL125-NH2's activity, its potential as an effective photocatalyst is determined. This leads to illuminating results for FeMiL125-NH2's candidacy in the development of WOR-based clean energy resources. Keywords: Chemistry; Biophysics; Metal-Organic Frameworks
