The efficiency of using photoelectrocatalysis (PEC) to degrade refractory organic pollutants depends to a large extent on the properties of the photoanode semiconductor. Therefore, the selection of a … WebThere also exist cases where different substances crystallize in a way that a new ‘pure substance’ forms. This only exists in crystal form. For example, Blue Vitriol is copper sulfate pentahydrate, CuSO₄.5H₂0, and it is a ‘pure substance’ as long as it remains in its crystalline form. If you dissolve it, it splits in copper sulfate and water.
