After Housing Policy: Housing and the UK General Election 2001

This paper describes the results of a review of the housing content of UK General Election 2001 manifestos. Housing policy was of little importance during the election campaign. The main British political parties had, essentially, a shared housing agenda - to promote and facilitate home ownership, support area and community regeneration, tackle homelessness, improve the private rented sector, and prevent building on greenfield sites. Many issues of importance to housing specialists received little or no attention, most notably that of low demand. Some policy variations within the UK were evident, for example in attitudes towards greenfield development, home ownership and stock transfer. The paper concludes that differences in housing policy are emerging within the UK as part of a new politics of devolution and that the days of a single housing policy approach for the UK are over.

General insight into CO oxidation: A density functional theory study of the reaction mechanism on platinum oxides

CO oxidation on PtO2(110) has been studied using density functional theory calculations. Four possible reaction mechanisms were investigated and the most feasible one is the following: (i) the O at the bridge site of PtO2(110) reacts with CO on the coordinatively unsaturated site (CUS) with a negligible barrier; (ii) O-2 adsorbs on the bridge site and then interacts with CO on the CUS to form an OO-CO complex; (iii) the bond of O-OCO breaks to produce CO2 with a small barrier (0.01 eV). The CO oxidation mechanisms on metals and metal oxides are rationalized by a simple model: The O-surface bonding determines the reactivity on surfaces; it also determines whether the atomic or molecular mechanism is preferred. The reactivity on metal oxides is further found to be related to the 3rd ionization energy of the metal atom.
