Improved catalytic performance of Pt/TiO2 nanotubes electrode for ammonia oxidation under UV-light illumination

Improving the Electrocatalytic Activity of Pt Monolayer Catalysts for Electrooxidation of Methanol, Ethanol and Ammonia by Tailoring the Surface Morphology of the Supporting Core

“…For example, the specific activity of Pt ML ‐decorated flower‐like Au particles is 0.32 mA cm −2 , which is markedly higher than that of 0.19 mA cm −2 on Pt ML ‐decorated spherical Au particles, indicating that the former have higher specific activity than the latter. Furthermore, the specific activity value of Pt ML ‐decorated flower‐like Au particles is similar to that reported for the pure Pt (all‐Pt) flower‐like particles under the same testing condition, as shown by our previous work ,. Figure b shows the CA curves measured on the Pt ML ‐decorated flower‐like Au particles and Pt ML ‐decorated spherical Au particles in 1 m KOH solution containing 0.1 m ammonia at −0.38 V (vs. SCE; current was normalized to the ECSA of Pt).…”

“…Previous work from our group also found that pure Pt particles with large numbers of protruding tips and edges on their surface have higher specific activity for the electrooxidation of ammonia and methanol compared to Pt particles with relatively smooth surfaces . It is interesting to note that the value of the specific activity of Pt ML ‐decorated flower‐like Au particles is similar to that of pure Pt (all‐Pt) flower‐like particles as reported in our previous work ,. This indicates that the Pt monolayer on the flower‐like Au particles shares similar features with the flower‐like pure Pt particles.…”

Preparation, characterization and environmental application of the composite electrode TiO2‐NTs/SnO2—Sb with carbon aerogels

“…In recent years, great progress has been made in improving the electrocatalytic activity of electrodes. 12,13 Mixed metal oxide electrodes, known under the generic name dimensionally stable anodes (DSA), 14,15 and Boron-doped diamond (BDD) [16][17][18][19] electrode are two kinds of anodes. Based on previous studies on Ti/RuO 2,20,21 Ti/SnO 2 -Sb 22,23 and Ti/PbO 2 electrodes , 24,25 the titanium based tin oxide antimony (Ti/SnO 2 -Sb) form has been demonstrated to be not only highly effective for the electrochemical degradation of persistent pollutants, but also available at lower cost than noble oxides and with high overpotential for oxygen evolution.…”

Pt Monolayers on Electrodeposited Nanoparticles of Different Compositions for Ammonia Electro-Oxidation

“…Growing concern in energy and environmental issues has stimulated considerable research on the electro-oxidation of ammonia, since it addresses both clean energy supply and removal of pollutants [1][2][3][4][5][6]. Ammonia is a carbon-free chemical energy carrier, which has a high capacity of hydrogen storage (17.7 wt.%) and high energy density (3000 Wh kg −1 ) [1,7].…”
