Abstract :Well-defined photocatalyst with 3D morphologies have attracted the attention of scientists due to the more accessible reactive surfaces, easy to recover from reaction medium, and low aggregation. Within this scope, photocatalysis based on plasmonic metal-organic frameworks insert ignore into journalissuearticles values(MOFs); were synthesized and utilized as an alternative reactive platform for visible-light degradation of methylene blue insert ignore into journalissuearticles values(MB); under green LED irradiation for the first time. In order to reduce the recombination between electron-hole pairs, a stable oxidant, namely sodium persulfate insert ignore into journalissuearticles values(PS); was employed to accelerate the photocatalytic decolorization of MB. These feasible strategies demonstrated that a bleaching degree of 91% insert ignore into journalissuearticles values( i.e., in the presence of PS); within 120 min was achieved compared to the bare Au@UiO-66@Pdop NPs insert ignore into journalissuearticles values(bleaching degree 31%);. The obtained results from this study highlighted the superior properties of the newly synthesized core-shell Au@UiO-66@Pdop photocatalysts and clearly declared the great potential of the photo-responsive MOFs for organic pollutant degradations as well.
