Abstract :
Present is a hydrothermal process to fabricate hollow self-assembled Cu2(OH)2CO3 and CuO particles. Urea is employed to serve as not only a precipitant but also the source to afford the templates of gas bubbles. H2O2 may play a role as a catalytic agent to assist decomposition of urea. Polyvinyl pyrrolidone is employed to act as the structure-directing agent to control the topography of products. The as-prepared samples are characterised through X-ray diffraction, transmission electron microscopy and scanning electron microscopy. A probable forming mechanism is performed.
