Society confronts the pressing environmental challenges posed by the pervasive presence of toxic pollutants in aquatic ecosystems. The repercussions of contaminant release extend far and wide, endangering marine life and human well-being. While various techniques such as bioremediation, filtration, and adsorption have been employed for wastewater treatment, they grapple with cost effectiveness and overall efficiency issues. Advanced oxidative processes, including photocatalysis and Fenton, have emerged as viable solutions in response to the emerging contaminants. However, the efficacy of photocatalysis largely hinges on the choice of catalyst. Their distinctive attributes, such as chemical defects and exceptional stability, make perovskite oxides a promising catalyst. These materials can be synthesized through diverse methods, rendering them versatile and adaptable for widespread applications. Ongoing research endeavors are diligently focused on enhancing the performance of perovskite oxides, optimizing their integration into catalytic processes, and exploring innovative approaches for material immobilization. This comprehensive review seeks to elucidate the most pivotal advances in perovskite oxides and their composites within the wastewater treatment domain. Additionally, it sheds light on burgeoning research trends and multifaceted challenges confronting this field, which present insights into techniques for treating the antibiotic-contaminated environment, delving into innovative strategies, green technologies, challenges, and emerging trends.

“…The chemical formula for a general perovskite structure is ABX3, where "A" and "B" are cations and "X" is an anion. In halide perovskites, the "A" cation is typically an organic or inorganic cation, the "B" cation is a metal cation, and the "X" anion is a halide ion (such as iodide, bromide, or chloride) [2]. Halide perovskite CsPbI3, also known as cesium lead iodide, is a type of perovskite material that has gained significant attention in the field of solar cell research and optoelectronics due to its remarkable properties and potential applications.…”

Halide perovskite based materials have garnered substantial attention within the research community due to their numerous applications in scientific and engineering advancements. In this regard, the properties of cubic perovskite CsPbI3 have been investigated under varying hydrostatic pressures, encompassing structural, mechanical, optical, and electronic aspects. Employing density functional theory, a comprehensive analysis of CsPbI3 has been conducted, revealing its behavior under pressures ranging from 0 to 55GPa. Particularly, the computed lattice parameters and unit cell volumes exhibit significant reduction under elevated pressures. The intrinsic structure of CsPbI3 exhibits a direct band gap tuning (1.85 eV, 1.093eV, 0.93eV, 0.807eV, 0.759eV, 0.536eV and 0.350eV) at the Γ (Gamma) position at increasing external pressure (0 to 55 GPa). Remarkably, the material maintains its direct band gap characteristics under these pressures, retaining its optical activity. The alteration in bandgap arises from transformations in the density of states, impacting both the valence band maximum and the conduction band minimum. This mechanical response not only showcases the material's ductile behavior but also underscores its propensity to enhance its properties under external pressure. Moreover, the computed dielectric coefficients demonstrate a remarkable shift towards the ultraviolet (UV) range. As external pressure increases, this effect becomes more pronounced, leading to significant improvements in both optical absorption and conductivity within the CsPbI3 system. These enhancements predominantly occur within the UV range, presenting a compelling advantage for the material's potential application in solar cells.
