Carbon Nanomaterials in Direct Liquid Fuel Cells

Abstract

Fuel cells have attracted more attentions due to many advantages they can provide, including high energy efficiency and low environmental burden. To form a stable, low cost and efficient catalyst, we presented here the state of the art of electrocatalyst fabrication approaches, involving carbon nanotubes and their multifunctional nanocomposites incorporated with noble metals, such as Pt, Pd, Au, their binary and ternary systems. Both fuel oxidation reactions and oxygen reduction reactions were emphasized with comprehensive examples and future prospects.

Boosting the electrochemical performance of Li4Ti5O12 through nitrogen‐doped carbon coating

“…The intensity ratio of the two peaks ( I D / I G ) is considered as an indicator for the graphitization degree of carbon materials. In this work, the ratio close to 1 implies the low graphitization degree of the carbon yielded …”

Carbon-Supported Raney Nickel Catalyst for Acetone Hydrogenation with High Selectivity

“…Carbon materials have a variety of advantages (such as stable chemical-mechanical properties, ease with regards to reclamation [20][21][22][23][24]), and have wide applications in the metal catalysts as supports [25][26][27][28][29][30]. Moreover, the pore structures and surface properties of carbon materials can be adjusted by changing the carbon precursor, adjusting the carbonization temperature, and doping heteroatoms [31,32].…”

Preparation and Electrochemical Performance of Hollow Activated Carbon Fiber Self-Supported Electrode for Supercapacitor

“…Electrode materials have a great effect on the electrochemical properties of supercapacitors. Carbon materials for energy storage systems have drawn extreme attention due to their accessibility [7][8][9], especially for electrode materials, different allotropes (graphite, diamond, fullerenes/nanotubes), various micro textures, a rich variety of dimensionalities from 0 to 3D, availability in various forms (powder, fiber, foam, fabric and composite) and relatively low cost. Many carbon materials such as electrodes, carbon nanotubes [10][11][12], activated carbon [13][14][15], graphene [16][17][18] and activated carbon fiber [19][20][21] have been studied.…”
