Figure 4From: Avoiding Loss of Catalytic Activity of Pd Nanoparticles Partially Embedded in Nanoditches in SiC NanowiresTEM images of fresh (a) and used (c) catalyst (etching at 85°C for 30 min) showing that the Pd nanoparticles can easily migrate and grow in the calcination process whereas remain their size during the reaction on the situation of deep etching; (b) the test results showing that the activity and stability of catalysts only have a slightly decrease after 10 reaction cyclesBack to article page
