摘要: Abstract In this study, the composite consists of bismuth ferrite (BiFeO3) photocatalyst embedded into macroporous liquid natural rubber (LNR) matrices was fabricated to assess removal efficiency methylene blue (MB) dye under direct sunlight. The structural properties and morphology LNR-BiFeO3 were thoroughly characterised using spectroscopic microscopic methods. X-Ray diffractogram demonstrated successful inclusion BiFeO3 LNR network. During solar-driven photocatalytic activity LNR-BiFeO3, effects selected operating parameters on efficiency, such as catalyst dose, irradiation time, initial concentration, solution pH, determined. At optimum dose (0.15 g BiFeO3) time (3 h), degradation 10 ppm MB remarkably efficient 98.9 + 0.09 % have been successfully discarded from system. had managed degrade up 75 ppm with exceeding 89.0 %. order investigate mechanism monitoring mode, kinetics scavenger study carried out. outcomes revealed that did fit well Langmuir-Hinshelwood kinetic model, in which (Ebg = 1.76 eV) is responsible for photodegradation process OH―, O2― h+ assistance adsorption by composite. could be reused five cycles without any post-treatment or separation step, most importantly, no significant loss noted its activity. This eco-friendly economical approach will render new opportunities advanced great potential environmental remediation wastewater treatment.
