Water is one of the essential needs of any living ecosystem. It is considered a fundamental pillar in various aspects of our lives, including the continuity of life, hygiene and health, agriculture and food production, energy production, industry, transportation, and trade. With the minerals it contains, water has a significant impact on the biochemical reactions occurring in our bodies. It is crucial as a basic source for all vital activities necessary for the survival of living organisms, such as nutrition, circulation, respiration, excretion, and reproduction. Due to its role as a fundamental requirement for existence, the presence and quality of water are of great importance at every stage of the living environment (Akın et al., 2005). Globally, the consumption of various classes of drugs, whether prescription or over-the-counter, is increasing day by day. In our country, the population growth, industrial and economic growth, and the widespread use of fertilizers and pesticides in agriculture are making this threat increasingly severe. For this purpose, the study aims to prepare a GO/TiO2/Bdp catalyst through the hydrothermal method and evaluate its catalytic activity in the photocatalytic removal of tetracycline, an antibiotic, from aqueous solutions. The Modified Hummers method was employed for the production of graphene oxide (GO). The Hummers method involves the exothermic reaction of graphite powders with oxidants, resulting in unexpectedly high temperatures and the formation of harmful gases, among other hazardous processes. However, through modified processes, it can be transformed into a reliable GO synthesis method. Additionally, fluorescent dyes have garnered significant interest in the continuously expanding multidisciplinary scientific world. Recent advancements in diagnostics, imaging, treatment, and organic electroluminescent devices have rapidly increased interest in the development of next-generation dyes (Ulrich et al. 2008). Among the fluorescent organic dyes, derivatives of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (Bdp) are compounds of increasing importance. Their high fluorescent quantum yields, narrow emission bands, thermal and photo stability, and good solubility make Bdp compounds superior to other dye compounds (Ulrich et al. 2008, Loudet et al. 2007). For this purpose, a GO/TiO2 catalyst was combined with a bodipy derivative dye, resulting in the preparation of a triple GO/TiO2/Bdp catalyst. ORCID NO: 0000-0002-7934-0061
