A fuel-cell-type sensor for detection of formaldehyde in aqueous solution

Electrocatalytic oxidation of formaldehyde on nickel modified ionic liquid carbon paste electrode as a simple and efficient electrode

“…Formaldehyde is also used in technologically important processes such as electroless copper plating and the textile industries, and thus its oxidation is relevant to waste water treatment [20]. Hence, in the past few years, many reports have been published on the oxidation of HCHO under a wide range of conditions and on various electrodes [13,[20][21][22][23][24][25][26][27]. On the other hand, the use of Ni as a catalyst for electrooxidation of this compound is of interest because it is an inexpensive metal.…”

Electrocatalytic oxidation of formaldehyde on palladium nanoparticles electrodeposited on carbon ionic liquid composite electrode

“…Formaldehyde oxidation has been explored on different electrodes [4][5][6][7][8][9][10][11][12][13]. Systems with highly dispersed metal nanoparticles provide effective surface area and active sites necessary for efficient catalysis.…”

Nanoporous Pt Catalyst Modified by Sn Electrodeposition for Electrochemical Oxidation of Formaldehyde

“…[1,2] Formaldehyde has a high theoretical open circuit potential during its full four-electron oxidation. [2] This suggests that formaldehyde is a promising alternative to methanol in a fuel cell.…”

“…[13][14][15][16] Bimetallic Pt-Ru catalysts were examined as efficient electrocatalysts for formaldehyde oxida-tion. [1,17] Another kind of bimetallic catalyst is Pt-Sn, which demonstrates a superior activity towards formaldehyde oxidation. [18] These Pt-Sn catalysts covered Pt-modified SnO 2 thin film electrodes, [19] adsorbed Sn atoms on Pt [20] and Pt microparticles modified Sn/polyaniline (PANI) electrodes [21] etc.…”
