Direct conversion of CO2 with methane was studied over a selective catalyst to produce valuable chemicals. A ZrO2/TiO2 based catalyst was prepared by co-participation and wet impregnation methods. The catalyst was characterized by different technique

The propane dehydrogenation assisted by CO2 was investigated by using zirconia and titania catalysts. The objective of the research was to assist the olefins yield of propylene and ethylene from the dehydrogenation of propane gas. The catalysts were

We present an alternative synthetic route to acrylic acid, starting from the platform chemical lactic acid and using heterogeneous catalysis. To improve selectivity, we designed an indirect dehydration reaction that proceeds via acetoxylation of lact

A new approach to achieving chemical mapping on a nanoscale is described that can provide 2D and tomographic images of surface and near-surface structure. The method comprises dissolving material from the surface of the sample by applying a series of

The telescopic conversion of glucose to fructose and then 5-hydroxymethylfurfural (5-HMF), the latter a potential, bio-derived platform chemical feedstock, has been explored over a family of bifunctional sulfated zirconia catalysts possessing tuneabl

New adsorbents based on MCM-41 have been developed for the adsorption and decomposition of HCN and CNCl. Adsorption of CNCl is provided by diaminoalkylsilane tethers bound to the surface. Reactivity towards HCN is provided by Cu2+ ions complexed by t

A new and potentially valuable approach to the study of the acidity and reactivity of the surfaces of solid acid materials is described. The technique uses a combination of constant rate thermal analysis (CRTA) with the rate jump technique (CRTA-RJ)

In heterogeneous catalysis the identification of the active site and crucially its location to prevent unwanted sintering and deactivation during the transformation of the precursor to active catalyst require the integration of dynamic in situ imagin
