Abstract

A series of palladium doped barium-based cerium (BaCe1-xPdxO3-δ) catalysts were prepared by the sol–gel method. The catalytic properties of BaCe1-xPdxO3-δ for the oxidation of carbon monoxide were studied. The results show that Pd doping can effectively inhibit the crystal size of catalyst powder, and the specific surface area of the catalyst increases with the increase of doping ratio. Palladium doping significantly improved the catalytic activity of barium ceric acid-based catalyst for CO oxidation. BaCe0.96Pd0.04O3-δ had the best catalytic activity for CO oxidation. After calcination at high temperature, the BaCeO3 perovskite is stable.
Pd掺杂BaCeO3的CO催化氧化性能
采用溶胶-凝胶法制备了一系列掺钯钡基铈(BaCe1-xPdxO3-δ)催化剂。研究了BaCe1-xPdxO3-δ对一氧化碳氧化的催化性能。结果表明,钯掺杂能有效抑制催化剂粉末的晶粒尺寸,催化剂的比表面积随着掺杂比的增加而增大。钯的掺杂显著提高了铈酸钡基催化剂对CO氧化的催化活性。BaCe0.96Pd0.04O3-δ对CO氧化的催化活性最好。经高温煅烧后,BaCeO3钙钛矿是稳定的。
