ABSTRACT
The remarkable mechanical and chemical characteristics of graphene have garnered significant interest in scientific investigations aimed at addressing severe environmental problems and energy shortages. A concerning problem is the careless disposal of industrial wastes that contain a variety of organic contaminants in water bodies. In order to create the ADGCAAQ light harvesting photocatalyst, a simple and extremely effective condensation process involving 1, 4-diamino anthraquinone (AAQ) and graphene generated from aloe vera (ADG) has been urbanized. Several approaches are used to analyze the newly constructed photocatalyst, indicating that it has the requisite potential to degrade 4-nitrophenol. By analyzing the degradation rate and order reaction of the degradation process, the kinetics of the degradation route have been used to analyze the mechanistic pathway for the degradation of 4-nitrophenol using a reducing agent and the ADGCAAQ photocatalyst. Under outside solar spectrum conditions, the photocatalytic activity of ADGCAAQ photocatalyst tested with 4-nitrophenol shows significant degradation efficiency with reducing agent H2O2.
Significance of the study:
This study introduces the ADGCAAQ photocatalyst, showcasing its potential to address environmental challenges, particularly the degradation of organic pollutants like 4-nitrophenol in water bodies. By leveraging the unique properties of graphene derived from aloe vera, this research highlights an innovative, sustainable solution for water purification. The findings promote the practical application of photocatalysts in environmental remediation, advancing efforts toward cleaner water resources.
Summary of the study:
This research presents the ADGCAAQ photocatalyst, developed from aloe vera-derived graphene and 1, 4-diamino anthraquinone, demonstrating its effectiveness in degrading 4-nitrophenol under solar light. The study details the photocatalyst’s synthesis through a condensation method and its impressive properties, such as slow charge carrier recombination and high molar absorption. The ADGCAAQ photocatalyst shows significant degradation efficiency with H2O2, highlighting its potential in environmental pollution mitigation.
