Sunlight Active (CoTiO3) – Titania (TiO2) Catalyst with Effective Activity for Dye Degradation and H+ Evolution
… times effective than TiO2 under visible light to Acid Orange 7 dye. At the same time the catalyst can produce 78 times more hydrogen than pure TiO2. The results show that there is a co-catalytic effect among the substrate (TiO2-rutile) and the CoTiO3. The chemical composition, phases and …

Effects of different frequencies and other variables on the salicylic acid and terephthalic acid dosimeters applied to the advanced Fenton process and activated carbon cloth
… radicals was determined by use of the salicylic acid (SA) and terephthalic acid (TA) dosimeters. Using SA, the ability of the frequencies to produce hydroxyl radicals in the presence of the oxidant hydrogen peroxide was assessed. Additionally, the use of selected ultrasonic frequencies was …
