Patent number: 11827792Abstract: A composite nanomaterial of ZnO impregnated by, e.g., a green copper phthalocyanine compound (CuPc) can be an efficient solar light photocatalyst for water remediation. The composite may include hollow shell microspheres and hollow nanospheres of CuPc-ZnO. CuPc may function as a templating and/or structure modifying agent, e.g., for forming hollow microspheres and/or nanospheres of ZnO particles. The composite can photocatalyze the degradation of organic pollutants such as crystal violet (CV) and 2,4-dichlorophenoxyacetic acid as well as microbes in water under solar light irradiation. The ZnO—CuPc composite can be stable and recyclable under solar irradiation.Type: GrantFiled: May 15, 2023Date of Patent: November 28, 2023Assignee: Imam Abdulrahman Bin Faisal UniversityInventors: Tamer Ezzat Youssef Moustafa, Hanan Hussein Amin Mohamed Besisa

Publication number: 20230331581Abstract: A method for producing crystalline ?-Fe2O3 nanoparticles involving ultrasonic treatment of a solution of an iron (III)-containing precursor and an extract from the seeds of a plant in the family Linaceae. The method involves preparing an aqueous extract from the seeds of a plant in the family Linacae and dropwise addition of the extract to the solution of an iron (III)-containing precursor. The method yields crystalline nanoparticles of ?-Fe2O3 having a spherical morphology with a diameter of 100 nm to 300 nm, a mean surface area of 240 to 250 m2/g, and a type-II nitrogen adsorption-desorption BET isotherm with a H3 hysteresis loop. A method for the photocatalytic decomposition of organic pollutants using the nanoparticles is disclosed. An antibacterial composition containing the crystalline ?-Fe2O3 nanoparticles is also disclosed.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Applicant: Imam Abdulrahman Bin Faisal UniversityInventor: Hanan Hussein Amin MOHAMED
