a TEM image of palladium nanoparticles synthesized in toluene (orange outline indicating solvent) at 90 °C under conventional heating. b TEM image of elongated palladium nanoparticles synthesized via light treatment at 90 °C. c Silica-encapsulated AuBP nanoparticles isolated from the photothermal reaction in toluene. d Aggregated palladium nanorods synthesized in ethanol (violet outline) under conventional heating at 90 °C. e Palladium self-assemblies obtained from the photothermal reaction at 90 °C. f Isolated SiO2@AuBPs from the same reaction. g Palladium nanorods synthesized in ethanol at 70 °C under conventional heating. h Self-assemblies produced in the photothermal reaction at 70 °C. i Isolated SiO2@AuBPs from the same reaction. Scale bars for (a, b, d, e, g, h) 50 nm, and (c, f, i) 100 nm.
