Description
Technical field
The present invention relates to a kind of fuel cell catalytic oxidation formic acid with anode electrocatalyst and preparation method thereof, belong to the fuel cell material science and technology field.
Background technology
Fuel cell is owing to have the energy density height, be not subjected to the restriction of Carnot cycle in theory, can be converted into fuel molecule advantage such as electric energy, nearly zero pollution and becomes an important research direction of electro-catalysis.Proposed the fuel cell theory first from Grove W.R in 1839, and since having confirmed that hydrogen/oxygen fuel cell can be directly be converted into electric energy to chemical energy, hydrogen/oxygen fuel cell has developed rapidly.But, hydrogen much is difficult to the difficulty that overcomes because existing in storage, transportation and supply side, and the reformation hydrogen production cost of organic molecule is too high and factor such as battery structure complexity, making people that sight is turned to the organic molecule is the direct fuel liquid battery of fuel, particularly direct alcohol fuel battery.These micromolecule not only have little, the easy storage of toxicity, transportation, processing, the energy density height, advantages such as aboundresources, also have inner fuel directly to change simultaneously, simplicity of design and advantage such as easy to lubricate, attract various countries fuel cell studies persons' attention, and carried out a large amount of theories and application study.But methyl alcohol has certain toxicity, stimulates people's optic nerve.Simultaneously, methyl alcohol acts as a fuel and also has the another one problem, is exactly that methyl alcohol can enter cathodic reaction zone through film, takes place simultaneously in cathodic reaction zone oxidization of methanol and hydrogen reduction, thereby reduces cell output voltage.And formic acid is liquid at normal temperatures, and water-soluble rear section is dissociated into formate ion, and it repels mutually with electronegative Nafion film, thereby reduces fuel infiltration.Directly the output voltage of formic acid/oxygen fuel cell is 1.45V, is higher than the output voltage of direct methyl alcohol/oxygen fuel cell.
Gold electrode electrocatalytic oxidation property to formic acid under acid system is very poor, and relevant report seldom adopts noble metal platinum to make the catalyst of formic acid electroxidation mostly in the document.Be reported in the document on the gold electrode, the formic acid oxidation current density only is 0.04mA/cm
2(referring to J.Electroanal.Chem., 517 (2001) 95-100), the research for the catalytic oxidation of formic acid on gold electrode all is basic theoretical research (referring to J.Electroanal.Chem., 431 (1997) 243-247).Compare with platinum, the relative low price and more relatively at China's reserves of gold replaces costing an arm and a leg and reserves noble metals such as Pt, Rh seldom all have great importance on scientific research and industrial production with Au catalyst.And alloying can change the characteristic of metal.As the effects such as intensity, catalytic activity and selectivity of chemisorbed, all can also can promote the stability of metal in the time of alloying because of adding other metal formation alloy and changing.Introducing other metallic element formation alloy or intermetallic compound in Au catalyst can influence its electronic factor, thereby changes its anodic process to formic acid oxidation, improves catalytic oxidation performance.In addition, adopt alloy to do the use amount that catalyst can reduce gold, reduce cost.The act as a fuel research of galvanic anode eelctro-catalyst of at present relevant billon yet there are no report, prepare the billon catalyst of the catalytic oxidation formic acid of dissimilar bodies or support type by distinct methods, to the practicability that promotes fuel cell and theoretical research all with significant.
