Pt　coatings　were　synthesized　through　thermal　decomposition,　using　an　aminated　lignin　as　template.　SEM　results　show　that　the　prepared　Pt　coatings　have　different　morphologies,　such　as　pile-stacking,　network-linking　and　close-packing.　Addition　of　quaternary-ammonium-salt　lignin　porous　Pt　films　with　multi-stage　or　network　structures　can　be　obtained.　If　Vpt　:　V　lig　=　4:5,　Pt　particles　could　form　a　3D-network　structure.　Treated　at　500　°C,　different　types　of　morphologies　are　showed.　The　samples　treated　at　400　°C　show　larger　porous　surface　area　and　more　distinct　network　structure.
