Fabrication, characterization and electrochemical properties of porous hollow palladium spheres

Facile, Large-Scale, and Expeditious Synthesis of Hollow Co and Co@Fe Nanostructures: Application for Electromagnetic Wave Absorption

“…14−17 Kong and coworkers demonstrated porous hollow Pd spheres, which are able to greatly increase the specific surface area and improve electrochemical properties as an anode material of direct ethanol fuel cells. 14 Hollow magnetic metals, such as Fe, Co, Ni, and Fe−Co alloys, could be investigated as electromagnetic (EM) wave absorption materials. It is proven that other than granularity, phase structure, or shell thickness, the morphology is equally important in enhancing EM wave absorption property of hollow magnetic metallic materials.…”

“…In recent years, hollow materials have been of widespread interest owing to their application potential in lithium ion batteries, adsorption, wastewater treatment, biosensor, and catalysis. − Many nanosized hollow materials, including metals, polymers, and oxides, have been successfully synthesized. − Hollow metal materials are superior to their solid structure counterparts due to their high specific surface area, low density, optical absorption spectra, and surface plasmon resonance. − Kong and coworkers demonstrated porous hollow Pd spheres, which are able to greatly increase the specific surface area and improve electrochemical properties as an anode material of direct ethanol fuel cells .

Simulation of salt spray corrosion behaviour of micro-arc oxidation coating by laser induced Ag infiltration

“…Various methods are applied to evaluate the corrosion resistance of MAO coatings on Al alloys, such as electrochemical corrosion, immersion or salt spray tests [12][13][14]. Among these methods, the neutral salt spray test (NSST) is one of the most common and simple means to assess the corrosion performance [14][15][16].…”

However, much attention was paid to the consequences of the salt spray test, whereas relatively neglected to trace the corrosion sequential process and observe corrosion channels induced during the salt spray test [14][15][16].…”

“…Among these methods, the neutral salt spray test (NSST) is one of the most common and simple means to assess the corrosion performance [14][15][16]. However, much attention was paid to the consequences of the salt spray test, whereas relatively neglected to trace the corrosion sequential process and observe corrosion channels induced during the salt spray test [14][15][16]. These were owing to the fact that most corrosion channels were locally destroyed due to the formation of corrosion products during the NSST.…”
