Carbon nanotubes modified with catalyst—Promising material for fuel cells

Modification of Carbon Nanotubes with Cadmium Sulfide Quantum Dots to Obtain Electrode Materials for Current Sources

“…It was a powder with a bulk density of 25-30g/dm 3 . The outside diameter of nanotubes was about 10-30nm, the specific surface area was 230m 2 /g.…”

“…Due to its highly desirable properties, CNTs have profound applications such as catalyst support materials for different types of fuel cells. CVD methods, electrochemical and chemical methods for the fabrication of composites based on nanotubes and catalysts were proposed [3,4,5]. However, not all of these methods enable one to deposit catalyst nanoparticles of definite size onto supports.…”

Localization of Electrochemical Reactions in Electrocatalytic Processes on Nanocomposite Electrodes

“…Platinum, nickel and lead were chosen from metals [14,15] . Manganese [16] , molybdenum [17] , chromium [18] , cobalt and niobium oxides were used as metal oxides. The catalysts were deposited by electrochemical and chemical methods developed by us [14][15][16][17][18] .…”

“…Manganese [16] , molybdenum [17] , chromium [18] , cobalt and niobium oxides were used as metal oxides. The catalysts were deposited by electrochemical and chemical methods developed by us [14][15][16][17][18] . As an example, we chose MWCNTs with deposited manganese dioxide (Figure 1) [16] , which has a high oxygen evolution overpotential and hence a high catalytic activity.…”

“…The catalysts were deposited by electrochemical and chemical methods developed by us [14][15][16][17][18] . As an example, we chose MWCNTs with deposited manganese dioxide (Figure 1) [16] , which has a high oxygen evolution overpotential and hence a high catalytic activity. From the above series of catalysts [2] we chose for comparison the cheapest material (lead).…”
