Cu and Zn‐doped Cu ferrites were synthesized by sol–gel auto‐combustion method. The samples were characterized by XRD, SEM, EDX, VSM, FT‐IR, and DRS methods. Powder XRD analysis and FT‐IR spectroscopy confirmed the formation of ferrites spinel phase. The crystallite sizes were calculated using Scherrer's equation. The morphologies and sizes of the synthesized nanoparticles have been observed by scanning electron microscopy. The saturation magnetization (MS) is obtained from VSM data. The energy band gaps were calculated from UV–DRS absorption data. Removal of Direct Red 264 was carried out by CuFe2O4 and Zn‐doped CuFe2O4 as catalysts under a visible lamp. The kinetic and isothermic analysis of photocatalytic degradation was studied. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13109, 2019

Photocatalytic degradation of direct red 264 under visible light using NiFe2O4 and Zn‐doped NiFe2O4 nanoparticles was the primary goal of this work. Hence, NiFe2O4 and Zn‐doped NiFe2O4 nanoparticles were prepared by the sol–gel auto combustion method. The powder X‐ray diffraction pattern unveiled the formation of spinel phase of NiFe2O4 with the average crystallite size determined from the Scherrer equation. The FTIR spectra of the samples revealed the vibration bands of Fe–O and Ni–O. The morphology and size of the synthesized nanoparticles have been observed by scanning electron microscopy. The band gap calculated using Kubelka–Munk function from the UV–visible diffuse reflectance spectra. Finally, removal of azo dye and corresponding kinetic and isothermic studies was examined. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13097, 2019

As the human population grows, the anthropogenic impacts from various agricultural and industrial processes produce unwanted contaminants in the environment. The accurate, sensitive and rapid detection of such contaminants is vital for human health and safety. Surface-enhanced Raman spectroscopy (SERS) is a valuable analytical tool with wide applications in environmental contaminant monitoring. The aim of this review is to summarize recent advancements within SERS research as it applies to environmental detection, with a focus on research published or accessible from January 2021 through December 2021 including early-access publications. Our goal is to provide a wide breadth of information that can be used to provide background knowledge of the field, as well as inform and encourage further development of SERS techniques in protecting environmental quality and safety. Specifically, we highlight the characteristics of effective SERS nanosubstrates, and explore methods for the SERS detection of inorganic, organic, and biological contaminants including heavy metals, pharmaceuticals, plastic particles, synthetic dyes, pesticides, viruses, bacteria and mycotoxins. We also discuss the current limitations of SERS technologies in environmental detection and propose several avenues for future investigation. We encourage researchers to fill in the identified gaps so that SERS can be implemented in a real-world environment more effectively and efficiently, ultimately providing reliable and timely data to help and make science-based strategies and policies to protect environmental safety and public health.
