The book "Ni-Cu-Ag-Alloys & MWCNT Composites for Environmental Applications" written by T. Sivaranjani provides a comprehensive overview of the synthesis, characterization, and applications of Ni-Cu-Ag alloys and their composites with multi-walled carbon nanotubes (MWCNTs) for environmental applications. The book is focused on the reduction of Cr(VI) and hydrogen evolution reaction (HER) as potential applications of these materials. The author describes the various methods of synthesis for these materials, including electrochemical and chemical reduction methods, and their subsequent characterization using a range of analytical techniques such as X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray spectroscopy. The book also highlights the importance of tuning the composition and morphology of the materials to optimize their performance in environmental applications. The book emphasizes the use of Ni-Cu-Ag alloys and their composites with MWCNTs for the reduction of toxic Cr(VI) ions in water, as well as for the HER process to generate hydrogen as a clean energy source. The author presents the latest research on the electrochemical performance of these materials and their potential applications in water treatment and energy generation. Overall, "Ni-Cu-Ag-Alloys & MWCNT Composites for Environmental Applications" is a valuable reference for researchers and professionals in the fields of materials science, environmental science, and electrochemistry who are interested in the synthesis and applications of advanced materials for environmental remediation and energy generation. The book provides an in-depth understanding of the synthesis, characterization, and applications of Ni-Cu-Ag alloys and their composites with MWCNTs, and highlights their potential for a range of environmental applications.
