This article discusses the viability of using agents such as niobium photocatalyst in decreasing higher energy of the band gap. To do so competitively withT iO2, the presence of oxidation helpers such as H2O2 and O3 could present surprising results in the catalytic performance due to higher generation of OH o radicals. Oxidation helpers are shown to assist in obtaining larger are oxides and textural properties different from commercial niobium oxide, and enhancing its catalytic activity in free cyanide removing. The article presents experimental results of cyanide photodegradation of 100mg/l with Degussa P-25 T iO2 and Nb2O53H2O, using a type CPC photoreactor and sunlight as the radiation source. Taking an inclination equal to Cartagena lati...
