Synthesis and immobilization of cupric oxide particles using X-ray raiolysis

We demonstrated synthesis and immobilization of cupric oxide particles using X-ray radiolysis directly from a liquid solution. The X-ray radiolysis of CuSO4 and Cu(CH3COO)2 solutions was observed to produce higher-order microstructures consisting of cupric oxide (CuO, Cu2O, Cu4O3) particles and Cu particles. The sizes of the particles depended on the ratio of ethanol in the stock solution and the surface of the substrate. The results indicate that there are several routes and reaction processes for these particles and aggregation to be synthesized. The technique of X-ray radiolysis enables us to achieve the rapid and easy synthesis of higher-order structures consisting of cupric oxide and copper particles.
