Improved 4-nitrophenol removal at Ti/RuO-SbO-TiO laser-made anodes.

In this study, binary and ternary mixed metal oxide anodes of Ti/RuO-SbO and Ti/RuO-SbO-TiO were prepared using two different heating methods: conventional furnace and alternative CO laser heating. The produced anodes were physically and electrochemically characterized by using different techniques. The main difference found in the laser-made anodes was their more compact morphology, without the common deep cracks found in anodes made by typical thermal decomposition, which showed an important correlation with the prolonged accelerated service life.
