Novel SnO 2-modified hydrozincite photocatalyst: Material design and application in efficient micropollutants degradation in wastewater

In this work novel photocatalysts have been synthesized based on hydrozincite and SnO2 with varying mol% of SnO2 in hydrozincite. The photocatalysts were prepared via chemical co-precipitation using thermal urea hydrolysis, without calcination or activation processes, and were applied in the photode...
