AbstractHeterogeneous gold nanocatalysts have both inspired researchers with their unique catalytic performance and frustrated them due to the contradictions observed in their activities and stabilities. A recent breakthrough has shown that gold nanoparticles (NPs) can retain their catalytically active size over a MgGa2O4 spinet support upon sintering at high temperatures. Herein, we report the catalytic activity of anti-sintering AuGMgGa(2)O(4) for use in water gas shift reaction (WGSR) and catalytic combustion reactions, and the promoting effect of ceria. Upon adding ceria to 800 degrees C-aged AuGMgGa(2)O(4), the CO conversion in the WGSR was increased from similar to 1.5% to similar to 34.0% at 450 degrees C, and the "light-off" temperatures (T-50) for methane combustion and CO oxidation were decreased by similar to 80 and similar to 100 degrees C, respectively. Characterizations using XRD, HAADF-STEM, EDS mapping, H-2-TPR, XPS, and DRIFTS confirmed the proximate contact of Au with ceria and their significant synergistic effect, which thereby combined the benefits of ceria toward the dissociation of H2O or O-2 and the Au NPs toward activating CO or CH4. These results show that this stepwise stabilization-activation strategy is efficient for rationally constructing stable and active gold nanocatalysts, which may open up possibilities for the wide application of gold nanocatalysts at elevated temperatures.
