Compositional and morphological engineering of in-situ‐grown Ag nanoparticles on Cu substrate for enhancing oxygen reduction reaction activity: A novel electrochemical redox tuning approach

Deep eutectic solvents as green solvents for materials preparation

“…Zhang et al developed an electrochemical activation process to trigger a reversible phase change reaction and surface reconstruction to synthesize highly active and stable self-supporting Ag nanoparticles grown on a Cu substrate. 104 Activated Ag NPs/Cu have a larger surface area, more accessible active sites, and strong metal–support interaction with tailored atomic/electronic structure, thereby improving electrochemical catalytic activity. The electrode optimized by the subsequent ion-exchange method shows ORR performance equal to or better than that of the most advanced Pt/C and has excellent electrochemical stability and methanol tolerance.…”

Ionic Liquid‐Based Polymer Nanocomposites for Sensors, Energy, Biomedicine, and Environmental Applications: Roadmap to the Future

“…The investigation of ILs is a multidisciplinary endeavor that involves analytical chemistry, [24] materials science, [25] chemical engineering, [26] and environmental science. [27] Furthermore, ILs show clear advantages for the preparation, catalysis, [28] physical chemistry, [29] electrochemistry, [30] energy fuels, [31] heredity, [32] nuclear physics, [33] medicinal chemistry, [34] engineering, [35] at manufacturing and laboratory scales. Figure 3 shows that the primary emphasis of the fields of interest of ILs is centered on material science, physical chemistry, chemical engineering, and multipurpose chemistry.…”

Recent Advances in the Synthesis of Inorganic Materials Using Environmentally Friendly Media

“…It was, suitable for the catalysis of methanol oxidation [ 100 ]; for the synthesis of NiS 2 nanospheres [ 101 ]; and, very interestingly, for the modification of Fe 2 O 3 NPs to produce very specific electrochemical sensors—for H 2 O 2 , acetylcholine and the antibiotic dapsone [ 102 ]. Furthermore, ChCl:EG was used as a carrier and disperser for SiO 2 @Fe 3 O 4 (silica-coated magnetite) ferrofluids selective for Meloxicam [ 103 ], to electrodeposit Ni-Al nanocomposite coatings from NiCl 2 and aluminum dispersions [ 104 ], to synthesize platinum hollow-opened structures with enhanced performance in the electro-chemical oxidation of methanol [ 105 ], and as a solvent for assembling Ag nanoparticles onto copper substrates [ 106 ]. Glyceline was employed in the solvothermal preparation of functionalized metal-organic framework (MOF) nanoparticles containing zirconium [ 107 ], to immobilize Pd nanoparticles [ 108 ], and to deposit ZnO in situ on graphene sheets [ 109 ].…”
