Highly Efficient Photocatalyst Fabricated from the Chemical Recycling of Iron Waste and Natural Zeolite for Super Dye Degradation.

In this paper, FeO and FeO-zeolite nanopowders are prepared by chemical precipitation utilizing the rusted iron waste and natural zeolite. In addition to the nanomorphologies; the chemical composition, structural parameters, and optical properties are examined using many techniques. The FeO-zeolite photocatalyst showed smaller sizes and higher light absorption in visible light than FeO.

Photocatalytic Activity of Revolutionary and 's Bio-Capped Silver Nanoparticles for Industrial Wastewater Treatment.

More suitable wastewater treatment schemes need to be developed to get rid of harmful dyes and pigments before they are discharged, primarily from apparel and textile factories, into water bodies. Silver nanoparticles (Ag-NPs) are very effective, reductive nanocatalysts that can degrade many organic dyes. In this study, Ag-NPs are stabilized and capped with bioactive compounds such as , , and from marine macroalgae extracts to produce Ag[GE], Ag[TE], and Ag[EE] NPs.
