Efficient nanostructured heterogeneous catalysts by electrochemical etching of partially crystallized Fe-based metallic glass ribbons

Journal of Materials Science and Technology, 2021
Although an increasing interest has been attracted to further develop heterostructured catalysts from metallic glasses (MGs) by heat treatment, overcoming surface oxidation effect is still a critical problem for such environmental catalysts.

Electrochemical Etching Switches Electrocatalytic Oxygen Evolution Pathway of IrOx /Y2 O3 from Adsorbate Evolution Mechanism to Lattice-Oxygen-Mediated Mechanism.

Small, 2023
Oxygen evolution reaction (OER) plays key roles in electrochemical energy conversion devices. Recent advances have demonstrated that OER catalysts through lattice oxygen-mediated mechanism (LOM) can bypass the scaling relation-induced limitations on ...

Electrochemical etching modes of 4H-SiC in KOH solutions

Semiconductor Science and Technology, 2023
Electrochemical etching is a promising wet etching technology for preparing porous structures and the flat surface etching of 4H-SiC. In this study, the effects of current density and KOH concentration on the etching of 4H-SiC were investigated. We found

Wire electrochemical etching of superhydrophobic 304 stainless steel surfaces based on high local current density with neutral electrolyte

Applications of Surface Science, 2022
Possessing special wetting properties, superhydrophobic surfaces on 304 SS substrates have great application prospects in various fields. However, due to the excellent corrosion resistance of 304 SS, currently, only strong oxidants can directly process ...

Highly efficient and damage-free polishing of GaN (0 0 0 1) by electrochemical etching-enhanced CMP process

Applied Surface Science, 2020
An electrochemical etching-enhanced CMP process was proposed to realize the highly efficient and damage-free finishing of GaN. In this process, electrochemical etching was first used to remove the damaged layer induced by grinding or lapping, and CMP was

A generic approach of polishing metals via isotropic electrochemical etching

International Journal of Machine Tools and Manufacture, 2020
Isotropic etching polishing (IEP), which is based on the merging of hemispherical holes that are formed by isotropic etching, is proposed in this study as a universal metal finishing approach.

Computational simulation and efficient evaluation on corrosion inhibitors for electrochemical etching on aluminum foil

Corrosion Science, 2021
The tunnel density and capacitance of etched aluminum foils would be significantly decreased for excessive dissolution during electrochemical etching process. The addition of low-concentration corrosion inhibitor solutions effectively improved the tunnel

Electrochemical etching

Electrochimica Acta, 1983
Silver faces with only a few exactly known dislocation emergence points were etched electrochemically. Deep pyramidal etch pits were observed on the screw dislocations whereas flat-bottomed pits arise on the edge dislocations. Qualitatively, this fact corresponds to the results obtained with natural, i.e. as-grown from the vapour phase, {0001}-faces of
