Semisolid Al–Ga composites fabricated at room temperature for hydrogen generation

Abstract

A semisolid Al–Ga composite fabricated at room temperature is used as a novel material to generate hydrogen from pure water.

Liquid Metals in Catalysis for Energy Applications

“…However, this method is critically limited by the development of a naturally formed thin oxide layer that hinders the reactivity of aluminum with water. 141 Therefore, a number of LM-based catalysts have been developed to facilitate this reaction, including pure Ga, 142,143 Ga-Sn/In/Zn, 144,145 Galinstan, 144,146 and other multicomponent alloys (Ga/Bi/Pb/Sn) 147 and (Ga/In/Sn/Zn). 148 Ga-based ALMs can significantly increase Al activity toward the Al-water reaction by reducing the size of the Al reactant (increasing the reaction surface area), impeding the development of aluminum oxides, and reducing the surface energy.…”

Liquid metal biomaterials for biomedical imaging

“…Commonly used inorganic materials include metallic nanoparticles (such as gold (Au), aluminum (Al), copper (Cu), silver (Ag)), as well as non-metallic particles (such as Cu oxide, Ti oxide, silicon (Si) oxide and carbon nanotubes). [31][32][33][34][35][36][37][38] As an example, Fig. 4A is a schematic illustration of the synthesis of Cu-EGaIn materials (a mixture of EGaIn and Cu particles).…”

Synchronously Producing H2 and Purifying Methyl Orange-Polluted Water through the Reaction of an Al–GaInSn Alloy Plate and H2O

“…H 2 is produced by active metals, such as lithium, sodium, and potassium, when they react with pure water (H 2 O) at room temperature. However, these active metals are difficult to handle and transport, and the reaction is too exothermic and dangerous for practical uses. , Al is the most abundant metal in the earth’s crust (7.45 wt %), having a low density (2.7 g cm –3 ) and low price (2.48 $ kg –1 as of 2021) . Moreover, Al has high mass and volume energy densities of 3.09 × 10 7 J kg –1 and 8.34 × 10 10 J m –3 , respectively .…”
