Abstract: Photocatalysis has garnered significant attention for its potential in environmental remediation, energy conversion, and sustainable chemistry. Metal-organic frameworks (MOFs) have emerged as promising photocatalytic materials due to their tunable structures, high surface areas, and unique optical properties. Among them, a newly synthesized copper-benzene-1, 3, 5-tricarboxylic acid (Cu-BTC) MOF, [Cu3(C9H3O6)2].3H2O{18H2O} has shown remarkable potential as a photocatalyst. In this work, the synthesis and characterization of a novel [Cu3(C9H3O6)2].3H2O{18H2O} for its photocatalytic applications is described. The synthesis of [Cu3(C9H3O6)2].3H2O{18H2O} was achieved through a solvothermal method employing Copper (II) Nitrate trihydrate and benzene-1, 3, 5-tricarboxylic acid as precursors in a suitable solvent. The synthesized [Cu3(C9H3O6)2].3H2O{18H2O}) was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), Scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDS), Single crystal and Thermogravimetric (TGA) analysis. The photocatalytic activity of ([Cu3(C9H3O6)2].3H2O{18H2O}) was evaluated in the transformation of Lissamine green SF (LGSF) and Tetraethylrhodamine (TeRh) under solar light irradiation. The intermediate compounds obtained during the transformation of LGSF under photocatalysis were detected using a gas chromatography-mass spectrometer (GC-MS). The recyclability of [Cu3(C9H3O6)2].3H2O{18H2O}was investigated to demonstrate its stability, robustness and potential for practical applications. Conclusively, the [Cu3(C9H3O6)2].3H2O{18H2O} was proven to be an effective catalyst in the mineralization of LGSF and TeRh.

Abstract: Piper capense, widely known as Timiz, is an important spice from the Piperaceae family, native to East Africa, particularly in Ethiopia’s southwestern areas. Traditionally used for a myriad of health issues, Timiz holds a significant place in Ethiopian cuisine, embodying cultural traditions. The plant is distinctive in its morphology, with "timiz" in Amharic indicating its curly form. The flavor profile of Timiz is notably unique, exhibiting a milder and sweeter taste that is reminiscent of cloves and cardamom, which enhances its culinary versatility. Typically, the harvested and dried seed spikes are appreciated for their aromatic properties, which are further enhanced through traditional smoking methods. This review explores the traditional medicinal uses of Timiz, relying on ethnobotanical data that illustrate its employment among various African communities for treating ailments like digestive issues, respiratory infections, and other health problems. The results of research on the collection, conservation of accessions, agronomic practices such as watering frequency and media types, as well as propagation methods, are also highlighted. Furthermore, the review identifies challenges within the value chain, such as a lack of awareness regarding processing methods and quality control, stressing the necessity for improved practices to boost Timiz's marketability. Future directions for research, production, and market integration of Timiz in Ethiopia are also discussed, underscoring the multifaceted significance of this spice in Ethiopian culture and medicine while advocating for sustainable agricultural methods to support its cultivation and conservation.
