聚苯胺-改性木质素磺酸钠复合材料基活性炭负载Pd催化剂对甲酸氧化的催化性能
Oxidation of formic acid over palladium catalyst supported on activated carbon derived from polyaniline and modified lignosulfonate composite
摘要
Abstract
Activated carbons ( AC ) were obtained through carbonization of polyaniline and modified lignosulfonate composite ( PAn-MLS) under different temperatures; they are characterized by fourier transform infrared spectroscopy ( FT-IR ) , Raman spectroscopy, nitrogen sorption and scanning electron microscope ( SEM) . With these carbon materials as the support, a series of Pd-AC catalysts for the oxidation of formic acid were prepared by liquid phase reduction and characterized by X-ray diffraction ( XRD) , transmission electron microscope ( TEM) and electrochemical analysis. The results show that with the activated carbon prepared at 800 ℃ ( AC800 ) as the support, the Pd-AC800 catalyst obtained performs best in the oxidation of formic acid; the palladium particles have an average size of 5. 4 nm and the electro-active surface area reaches 53. 78 m2/g. As the oxidation of formic acid over Pd-AC800 is realized through direct pathway rather than CO pathway, Pd-AC800 may be considered as a potential electrode material in direct formic acid fuel cells ( DFAFC) .关键词
