摘要

制备高效电催化剂是提高煤浆电解制氢技术制氢效率低的关键，笔者采用晶种生长法，以甲醛作为还原剂、正辛胺为溶剂、乙酰丙酮钯为前驱体、碳纤维为载体，制备钯纳米催化剂用于煤浆电解制氢阳极.采用XPS、TEM手段进行催化剂表征.结果表明：制备的钯催化剂尺寸约为8 nm，Pd主要以单质形式存在.与商用纯Pt电极相比，制备的钯电极催化活性提高了412%，有效提高了煤浆电解制氢效率.

钯纳米催化剂氢气煤浆电解

Abstract:

The preparation of highly efficient electrocatalyst is the key to improve the low hydrogen production efficiency of the coal slurry electrolysis hydrogen production technology. The author used crystal seed growth method to prepare palladium nano catalyst for the coal slurry electrolysis hydrogen production anode, using formaldehyde as the reducing agent-octylamine as the solvent, palladium acetylacetone as the precursor, and carbon fiber as the carrier. The catalysts were characterized by XPS and TEM. The results show that the size of the prepared palladium catalyst is about 8 nm, and Pd mainly exists in the form of simple substance Compared with the commercial pure Pt electrode, the catalytic activity of the prepared palladium electrode is increased by 412% which effectively improves the efficiency of hydrogen production from coal slurry electrolysis.
