Characterizations of the Pd/m–MoO3–P2O5/SiO2 catalyst. a HAADF-STEM image of Pd/m–MoO3–P2O5/SiO2. Inset shows the size distribution of the nanoparticles. Scale bar equals 20 nm. b Aberration-corrected ABF scanning transmission electron microscope image and c corresponding HAADF-STEM image of Pd/m–MoO3–P2O5/SiO2. Scale bars equal 5 nm. d STEM-EDS elemental mapping results for Pd/m–MoO3–P2O5/SiO2, showing a homogeneous distribution of Mo and P elements within nanoparticles and highly dispersed Pd. Scale bar equals 3 nm
