Apart from the similarities with high entropy alloys (HEAs), they have very unique characteristics that have attracted various studies. HECs have exhibited great performance in a variety of applications, and the possibilities are endless. In this work, spinel (CoCrFeMnNi)3O4 was synthesized on porous anodic aluminum oxide (AAO) as a photoanode and demonstrated substantial light absorption in the visible light spectrum with a band gap of 2.58 eV. The photoresponse performance of the HECs-AAO photoanode for water splitting was examined. The results indicate that the HECs have remarkable photoelectrochemical and photocatalytic activity. This discovery demonstrates HECs′ versatility in a variety of applications and their prospects for photocatalysis in particular. Furthermore, graphene has previously been used in a variety of surface-enhanced Raman scattering (SERS) applications. This study describes the formation of ordered gold nanoparticles (AuNPs) and graphene on a porous anodic aluminum oxide (AAO) substrate. The combination of AuNPs electromagnetic enhancement activity and graphene′s unique physical/chemical properties in the presence of AAO enhances SERS properties and enables microanalysis investigations. Numerous works will be compared to illustrate the critical role of each component in development. Additionally, this study aims to fill in the gaps in our understanding of the SERS enhancement mechanism.
