A robust self-stabilized electrode based on Al-based metallic glasses for a highly efficient hydrogen evolution reaction

Abstract

Al-based metallic glass ribbon with a nanoporous layer of high-entropy alloy is a robust advanced self-stabilized free-standing electrode for hydrogen evolution reaction.

Design and perspective of amorphous metal nanoparticles from laser synthesis and processing

“…amorphous Co@C NPs, 85 amorphous Fe@C NPs, 86 and Co-B MG-NPs 87 ). In this aspect, the single-phase nature of amorphous structure endows amorphous NPs with better corrosion resistance, 88,89 a more uniform distribution of chemically active sites, 90 etc. than their crystalline counterparts due to the absence of crystallographic defects and phase segregation.…”

High Density and Unit Activity Integrated in Amorphous Catalysts for Electrochemical Water Splitting

“…[ 100–106 ] Their drawbacks of scarcity and high cost prevent them from meeting the needs of the H 2 production process and restrict their practical application. Hence, it is time to seek novel alternative catalysts that exhibit excellent catalytic activity and stability such as amorphous materials, [ 107–113 ] high entropy alloy intermetallic oxides, [ 114–118 ] and perovskite‐based catalysts. [ 119–123 ]…”

“…Such preparation methods of amorphous catalysts, so far, include rapid solidification, [ 113 ] dealloying, [ 124 ] electrochemical activation, [ 49 ] coprecipitation, [ 36 ] photochemical metal–organic deposition, [ 28 ] ion exchange, [ 125 ] hydro/solvo‐thermal, [ 11 ] electrodeposition [ 10 ] etc., as shown in Figure a. Furthermore, we briefly introduce these methods for the preparation of amorphous catalysts with a comparison of their advantages and disadvantages in Table 1 .…”

The Pivotal Role of s‐, p‐, and f‐Block Metals in Water Electrolysis: Status Quo and Perspectives

“…Among these lean metals, those referred to Al, Ga, Sn, and Bi are usually utilized for the OER and HER catalysis, and they improve the OER and HER activity in terms of the following aspects. [ 103,105,206–231 ] i) These lean metals can be readily etched in both the alkaline and acidic solutions, generating beneficial results including the formation of pores and partial phase reconstruction. ii) They can be prone to hybrid with other metals to form the (ordered) intermetallics with high conductivity.…”
