Abstract
SrMg2FeH8 is a type of hydride compound that shows a lot of promise for use in optoelectronics and photocatalysis. I've analyzed its electronics structure to understand its function better. An analysis of its total electronic states shows that it behaves like a semiconductor with a moderate bandgap of 2.251 eV. For the purposes of photocatalysis, the bandgap is advantageous as it means that the material can absorb visible light quite readily. The examination related to materials optical properties - in terms of its refractive index and light absorption - confirms strong absorption to light in the visible and ultraviolet ranges. All of these characteristics make it a very worthwhile specimen for use in optoelectronic devices. The photocatalytic capacity of SrMg2FeH8 has been thoroughly studied with interest in its capacity to promote both oxidation and reduction reactions. The valence band edge located at 2.61 eV referenced to the normal hydrogen electrode would suggest it should be suitable to promote water oxidation processes. The conduction band edge was located at 0.36 eV, again referenced to the normal hydrogen electrode and while this described hydrogen evolution, it would seem kinetic limitations will require the use of co-catalysts in order to utilize hydrogen evolution efficiently. The strong optical absorption, combined with its electronics and photocatalytic properties, provides positive results for potential applications in hydrogen production,pollutant degradation and energy conversion technologies.

Key words: Hydride compounds, Optoelectronic properties, Photocatalysis, Band gap, Optical absorption, Hydrogen production.
