1. Comprehensive study combining surface science and real catalyst for NO direct decomposition

Author:
Masaaki Haneda; Yoshiaki Kintaichi; Isao Nakamura; Tadahiro Fujitani; Hideaki Hamada
Source:
Chemical communications 2002 v. no.23 pp. 2816-2817
ISSN:
1364-548X
Subject:
aluminum oxide; catalysts; catalytic activity; chemical reactions; models; nitric oxide; palladium
Abstract:
... The catalytic activity of Pd/Al₂O₃ prepared from various palladium precursors for direct NO decomposition is closely related to the fraction of surface step sites capable of dissociating NO, on the basis of a surface science study using single-crystal model catalyst. ...
