Anodized aluminum oxide (AAO) nanowell sensors for hydrogen detection

Hydrogen Detected by the Naked Eye: Optical Hydrogen Gas Sensors Based on Core/Shell Plasmonic Nanorod Metamaterials

“…It is extensively used in scientifi c research and industry, especially in glass and steel manufacturing, refi ning petroleum products, and in the chemical industry in general. [1][2][3] Hydrogen is a highly combustible colorless and odorless gas, extremely fl ammable in ambient atmospheric conditions at concentrations exceeding 4% by volume. [ 4 ] These properties are a deterrent for the adoption of hydrogen in industrial applications or in the exploitation of hydrogen-based technologies.…”

“…[ 1 ] This drives a demand for sensors able to detect accurately hydrogen gas at very low Adv. Mater.…”

Synthesis of pure and bimetallic Pd films supported in anodic alumina membranes by Solid State Reduction

“…As films, they can be used as hydrogen sensors [1][2][3][4][5], H 2 separation membranes [6] membrane reactors for hydrogenation and dehydrogenation [7,8], among others [9][10][11].…”

Nanostructures of Pd–Ni alloy deposited on carbon fibers for sensing hydrogen

“…For example, Pd nanofilms, nanowires and nanoparticles [1][2][3] have been widely applied in hydrogen sensors. Many methods have been applied to prepare of different nanostructures, including thermal evaporation [4], electroless technique [5], electrochemical step-edge decoration [6,7], self-assembly [8], sputter deposition [9], and so on. There are many types of hydrogen sensors applied the Pd nanomaterials based on different mechanisms, such as fiber optic type [10], electrochemical type [11], hot wire type [12], resistance type [13].…”
