The addition of Pd to Pt-based diesel oxidation catalysts is known enhance performance and restrict the anomalous growth Pt nanoparticles when subjected aging at high temperatures in oxidative environments. To gain a mechanistic understanding, we studied transport mobile species vapor phase, since phase primary route for sintering these catalysts. results are surprising: there 30-fold drop effective pressure Pt–Pd compared monometallic Pt. At same time, significant enhancement Pd, PdO, which...
Atomic regulation of metal catalysts, especially the active surface, is key to optimizing catalytic performance. In this work, we tuned surface Pd coordination by varying bismuth loadings in Pd–Bi alloy system, facilitating different performances for propane dehydrogenation (PDH) and acetylene semihydrogenation model reactions. situ X-ray absorption spectroscopy, atom-resolved scanning transmission electron microscopy combined with elemental distribution analysis, infrared photoelectron...
This article describes the synthesis and catalytic properties of supported, 2–3 nm platinum phosphide (PtP2) nanoparticles (NPs). Depending on P loading, two PtP2 structures are formed, that is, a surface (metallic) Pt core (Pt@PtP2) single-phase NPs. The were determined using extended X-ray absorption fine structure , in situ synchrotron diffraction, scanning transmission electron microscopy. In NPs, Pt2+ ions geometrically isolated by P22– ions, at Pt–Pt distance 4.02 Å, which is much...
Dyes and their derivatives have been found to be harmful aquatic organisms, discharging dye effluent without proper treatment into the environment can lead affect usability of water for distinct purposes, including drinking water, agriculture, commercial processes. To overcome this environmental crisis a cost-effective rice husk ash (RHA) derived catalyst was synthesized as Fenton new, environmentally, friendly used treat trypan blue (TB) from synthetic wastewater. SEM, EDX, XRD, FTIR were...
