| Abstract | This paper reports the synthesis of trioctylphosphine oxide (TOPO) assisted copper oxide (CuO) electrodes by a rapid hydrothermal technique. The effects of the capping agent (TOPO) on structural, morphological and electrochemical properties for different concentrations of the Cu precursor were investigated. Surface morphology was examined by using scanning electron microscopy (SEM) which showed a yarn ball-like morphological structure for a lower concentration of the Cu precursor and rising of leaves onto the yarn balls was observed for higher concentrations. The cyclic voltammogram (CV) study showed the highest specific capacitance of about 143 F g−1 for CuOT3 at 10 mV s−1 and an energy density of 18.1 W h kg−1 at 1 mA cm−2 with about 82% capacitance retention after 1000 CV cycles at 100 mV s−1 in 1 M aq. KOH. Also the statistical model for capacitance retention and specific capacitance using the fitted exponential model was studied. Therefore, the specific capacitance can be tailored by appropriate selection of concentrations of the Cu precursor and TOPO. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
