- Abstract
To reduce NOx emission, LnPW (Ln= La, Ce, Pr, Nd, Sm, Eu, Gd, Yb, Y; PW= PW12O40) were prepared and used for NOx adsorption and decomposition. The adsorption results showed that NOx adsorption capacity on LnPW were lower than phosphotungstic acid (HPW). After doping with HPW, the NOx adsorption ability of LnPW/HPW was improved significantly. NOx catalytic decomposition on LnPW/HPW was tested by rapid heating, the results showed that catalytic activity of LnPW/HPW was superior to HPW. The effects of doping ratio on NOx adsorption and decomposition were studied on the catalyst of EuPW/HPW, and the results showed that HPW played the role of NOx adsorbent, while EuPW was related to the NOx conversion and N2 selectivity.
