Ultra-fast synthesis of Ti/Ru0.3Ti0.7O2 anodes with superior electrochemical properties using an ionic liquid and laser calcination

Here, we combine CO2 laser heating and an ionic liquid solvent (i.e., methylimidazolium hydrogensulfate HMIM+ HSO4–) as innovative route to produce Ti/Ru0.3Ti0.7O2 anodes. For comparison purposes, the anodes were also prepared using conventional thermal treatment (in a furnace), by standard polymeric precursor method (also known Pechini method). heating, heated at power density of 0.4 W mm?2 up 550 °C kept this temperature for 40 s, followed instantaneous cooling. Using these conditions, total time spent anode (considering cooling) is just 9.7 min. It represents remarkable reduction in 446-fold 359-fold when compared with IL methods, respectively. The laser-prepared presented increase 63.4% 53.8% voltammetric charge, while charge transfer resistance decreases 9.6-fold 17.3-fold respectively, their correspondent furnace-made ones. Finally, superior electrocatalytic activity toward removal model pollutant atrazine observed produced most efficient, removing 81% 60 min, presents highest kinetic rate (0.062 min?1) lowest energy consumption (0.179 kWh L–1). excellent response innovatively synthesized study characterizes them encouraging advance search efficient materials be applied electrochemical oxidation organic compounds.
