The electrochemically reducing nature of the poly-(ethylene-glycol) solvent (PEG200) is exploited in a one-step electroless deposition of nano-fibrous platinum electrocatalyst. K 2 PtCl 6 is dissolved in poly-(ethylene-glycol) and applied to a substrate (here tin-doped indium oxide, ITO). The deposition process is conducted by rapid heating in a furnace in air. Upon ramping the temperature...
By using eco-friendly polydopamine as carbon and nitrogen precursor and commercial hydrophilic nano-CaCO 3 as hard-template; a one step, cost-effective and green method to synthesize nitrogen-doped porous carbon (NPC) is presented. A series of NPC samples with different nitrogen contents have been reported. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive...
