    • Deposition of nanoparticles onto carbon surfaces is described. Metal and/or metal oxide ions are deposited on a carbon surface by electrodeposition, such as by immersing a carbon and an anode in a salt bath, and applying a number of electrical pulses having a defined pulse width. The size, coverage density, and metallic composition of the nanoparticles may be affected by the pulse width of the electrical pulses, the number of electrical pulses, and the chemical composition of the salt bath, respectively. The carbon may be anodized before electrodeposition. If the carbon is a carbon precursor, after electrodeposition, the carbon precursor is carbonized to form a carbon. After electrodeposition, the carbon may be activated to form an activated carbon. The nanoparticles may serve as catalysts for activation rugosity of mesoporous carbons. The catalytically activated carbon materials may be used in all manner of devices that contain carbon materials.
    • 描述了将纳米颗粒沉积在碳表面上。 金属和/或金属氧化物离子通过电沉积沉积在碳表面上,例如通过将碳和阳极浸入盐浴中,并施加多个具有限定脉冲宽度的电脉冲。 纳米颗粒的尺寸,覆盖密度和金属组成可能分别受电脉冲的脉冲宽度,电脉冲数和盐浴的化学成分的影响。 碳可以在电沉积之前进行阳极氧化处理。 如果碳是碳前体,则在电沉积后,将碳前体碳化以形成碳。 电沉积后,碳可以被活化以形成活性炭。 纳米颗粒可以用作介孔碳的活化粗糙度的催化剂。 催化活性炭材料可以以包含碳材料的各种装置使用。
