Highly dispersed CuO/SiO2 catalysts were successfully synthesized by a green process of ball milling (BM) under solventfree and room temperature conditions. The structural evolution of CuO/SiO2 catalysts prepared by BM was elucidated by TGDSC, XRD, FTIR, and XPS characterizations. We found that the copper acetate precursor was dispersed over the layer of copper phyllosilicate which was ...

Quartz is a crystalline mineral of silicon dioxide, also referred to as Crystalline Silica. Quartz is the most abundant mineral on the earth's surface and the second most abundant mineral in the earth's crust. Beach and desert sand is primarily composed of quartz crystals due to quartz's high resistance to mechanical and chemical weathering.
