Electrochemical Synthesis of PbO2, Pb3O4 and PbO Films on a Transparent Conducting Substrate

Development of a Three-Dimensional Structured Carbon Fiber Felt/β-PbO2 Electrode and Its Application in Chemical Oxygen Demand Determination

“…Then this graphite sheet was poached in Na 2 CO 3 solution (20%, m/m) for half an hour and then washed with deionized water. The electro-deposition process [28][29][30] was the same as that for the CF/␤-PbO 2 electrode.…”

“…Then this felt was poached in Na 2 CO 3 solution (20%, m/m) for half an hour and then washed with deionized water. The compositions of plating solution [28][29][30] were: 0.5 mol L −1 Pb(NO 3 ) 2 , 0.1 mol L −1 HNO 3 and 0.6 mol L −1 Cu(NO 3 ) 2 . The electro-deposition process was performed in two steps: firstly, galvanostatic deposition was carried out at 25 mA cm −2 and 40 • C in a glass cell containing 150 mL of electrolyte for 60 min; secondly, galvanostatic deposition was carried out at 50 mA cm −2 and 55 • C for 60 min in the same cell containing renewed 150 mL of electrolyte.…”

“…The Ti/Sb 2 O 3 -SnO 2 electrode was placed in the plating solution, and then the first electro-deposition was carried out under constant current density of 30 mA cm −2 at 40 • C for 0.5 h to obtain the ␣-PbO 2 layer [31,32]. Finally, the second galvanostatic deposition [28][29][30] was carried out at 50 mA cm −2 and 55 • C in a small glass cell containing 150 mL of electrolyte (0.5 mol L −1 Pb(NO 3 ) 2 , 0.1 mol L −1 HNO 3 and 0.6 mol L −1 Cu(NO 3 ) 2 ) for 90 min. As a result, the electrode was covered by a thin film of navy blue ␤-PbO 2 .…”

Screen Printed Pb3O4 Films and Their Application to Photoresponsive and Photoelectrochemical Devices

“…Few studies regarding the syntheses of Pb 3 O 4 nanomaterials are available [5,6,7]. In addition, for thin films, deposition processes are limited to the electrochemical depositions of PbO 2 , which are followed by thermal treatments [4,6,8]. In this work, a new procedure for the deposition of lead (II, IV) oxide films by screen printing is presented as a cheaper and more flexible alternative to existing electrochemical methods, which are limited to electrically conductive substrates.…”

Исследование Механических, Электронных И Колебательных Свойств Оксидов Свинца Из Первых Принципов

“…Помимо объемных кристаллов широко используются наночастицы PbO [6][7][8][9], Pb 3 O 4 [10] и пленки PbO, PbO 2 , Pb 3 O 4 [11,12], что связано с их новыми интересными свойствами и возможностями применения в качестве на-норазмерных электронных устройств. Например, в нано-структурированном оксиде свинца ширина запрещенной зоны частиц размером 63 nm равна 5.52 eV [7], а при размере 12 nm уже 5.17 eV [13].…”
