| Abstract: | (hbox {CuBO}_{2}) is a novel material in the research field of transparent conducting oxide. In this study, (hbox {CuBO}_{2}) nanostructures have been synthesized via sol–gel method. The phase formation is confirmed using an X-ray diffractometer. Detailed morphological analysis is performed by field emission scanning electron microscopy and transmission electron microscopy. A novel uniform nanonetwork-like structure is obtained and its band gap is found to be 4.24 eV. In ultraviolet light irradiation, this as-synthesized sample shows efficient photocatalytic activity for degradation of organic dye Rhodamine B. The degradation efficiency and the rate constant were calculated as (sim )70% and (1.32times 10^{-3},hbox {min}^{-1}), respectively. This nanonetwork-like structure can be a potential candidate as the base material to attach various metals and metal oxide nanostructures to get highly efficient future photocatalysts. As a result, this study opens up a new gateway to fabricate novel environment-friendly nanocatalysts with high performance. |
