Metallic nanosponges for energy storage and conversion applications

“…[49][50][51] However, template-assisted methods have not produced desirable results with pristine noble metals because they require post-synthesis template removal processes. 52,53 Hence a template-free and sacricial template approach that does not require an additional template removal process is currently developed. For example, by employing sucrose as the sacricial so template, a large scale synthesis of transition metal (Cu, Co and Ni) nanosponges with excellent catalytic properties has been accomplished by heating a mixture of sucrose and metal salts.…”

“…54 Specically, amongst the Ag, Au, Pt, Pd and Cu nanosponges, palladium has displayed the highest hydrogen sorption and catalytic activity with a great structural retention aer catalytic operation. 54 Although monometallic nanosponges have gained signicant research interest in the application of catalysis, 52,54,55 optical sensors 53 and hydrogen storage, 54 bimetallic and polymetallic nanosponges seem to exhibit overall better performance due to the synergy of multiple metals. 56…”

“…For example, by employing sucrose as the sacrificial soft template, a large scale synthesis of transition metal (Cu, Co and Ni) nanosponges with excellent catalytic properties has been accomplished by heating a mixture of sucrose and metal salts. 52 Furthermore, to reduce the multiple steps and make the process amenable to a large number of metals, a rapid one-step process via kinetically controlled borohydride reduction was developed to synthesise noble metal (Au, Ag, Pt, and Pd) nanosponges. 53 This method was further extended to the fabrication of Ru nanosponges, which have found applications in optoelectronic nanodevices.…”

From Laves Phases to Quasicrystal Approximants in the Na–Au–Cd System

“…The exploratory synthesis of metal-rich, inorganic solids has revealed a collection of unprecedented crystal structures, distinct bonding motifs, and unique electronic features . Ternary systems containing metal constituents featuring exceedingly different electronegativities have been particularly bountiful, yielding a wide variety of exciting intermetallic compounds. − These compounds have attracted great interest because of their fascinating physical properties such as superconductivity, − topology, − magnetism, − and catalytic properties. − They also contain unique structural traits like complex networks, , clusters, quasicrystals, and their approximants . Nevertheless, the specific chemistry dictating crystal structure formation and the ensuing properties has remained ambiguous.…”

The Use of Synthesized CoO/Co3O4 Nanoparticles as A Corrosion Inhibitor of Low-Carbon Steel in 1 M HCl

“…More recently, the focus has been on studying the incorporation of natural substances containing organic compounds with inorganic nanoparticles, such as Al 2 O 3 , ZrO 2 , SiO 2 , TiO 2 , CdS, NiO, ZnO, cobalt complex, and Fe 3 O 4 [11][12][13]. This focus is due to nanoparticles' mechanical and physical properties, which stem from their large surface area and small particle size [14].…”
