Silver nanoparticles (Ag-NPs) readily transform in the environment, which modifies their properties and alters their transport, fate, and toxicity. It is essential to consider such transformations when assessing the potential environmental impact of Ag-NPs. This review discusses the major transformation processes of Ag-NPs in various aqueous environments, particularly transformations of the met...

Abstract Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied situ. Herein we present a comparative XAFS study where situ sulfidation Mo/δ-Al 2 O 3 and Ni/δ-Al is compared to δ-Al supported NiMo with different ratios. The also covers comparison Ni Mo using oxide supports as...
