The direct synthesis of H2O2 and in situ oxidation of methane: An investigation into the role of the support
The selective oxidation of methane to methanol, using H2O2 generated in situ from H2 and O2 has been investigated using bimetallic gold-palladium catalysts, prepared via an industrially relevant wet co-impregnation protocol on a range of zeolite and metal oxide supports. The choice of catalyst support was found to drastically influence catalyst performance, through control of both nanoparticle dispersion and Pd speciation. Notably in the case of those formulations prepared on metal oxides a direct correlation between catalytic performance towards H2O2 synthesis and methane valorisation exists, whereas in the case of the zeolitic-based analogues, no clear correlation could be drawn between activity towards individual reaction pathways.
期刊介绍:
Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues.
Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
