Abstract
The Co3O4 nanoparticles (NPs) embedded in nitrogen (N)-doped porous carbon (Co3O4 NPs@NPC) were dopped to copper-zeolitic imidazole frameworks (ZIF-67) and used as sonophotocatalyst and electrocatalyst. Herein, a facile in situ growth ultrasonic (US) strategy is reported for the synthesis of tightly connected C3N5-Cu-doped Co3O4 NPs @NPC nano-cubes heterojunction nanoarchitecture (NAs) by coupling C3N5 with Cu-doped Co3O4 NPs@NPC nanocubes. The linear sweep voltammetry (LSV) results show that the C3N5-Cu-doped Co3O4 NPs@NPC electrocatalyst has a remarkable electrocatalytic activity towards the hydrogen evolution reaction (HER). The sono-photocatalyst activity on sulfamethoxazole (SMX) degradation is due to synergistic effects of both superoxides (O2•−) and hydroxyl radicals (OH•). The results substantiate 98 % degradation of SMX within 120 min under sonophotodegradation efficiency. The reduction in electron (e-)-hole (h+) recombination is the main efficiency of sonophotodegradation of C3N5-Cu-doped Co3O4NPs@NPC. This effect was further complemented by the broadening of light absorption by C3N5, resulting in reduced degradation time. The enhanced sonophotocatalysis and electrocatalytic performance are due to their high surface area, enhanced conductivity, and faster charge transfer. This work demonstrated that C3N5- Cu-doped Co3O4NPs@NPC based sonophotocatalyst and electrocatalyst have great potential in SMX degradation and electrochemical water splitting for hydrogen production. It also shows superior biocompatibility due to C3N5′s role in reducing cytotoxicity compared to Cu-doped Co3O4 NPs@NPC.

Journal of Industrial and Engineering Chemistry is published monthly in English by the Korean Society of Industrial and Engineering Chemistry. JIEC brings together multidisciplinary interests in one journal and is to disseminate information on all aspects of research and development in industrial and engineering chemistry. Contributions in the form of research articles, short communications, notes and reviews are considered for publication. The editors welcome original contributions that have not been and are not to be published elsewhere. Instruction to authors and a manuscript submissions form are printed at the end of each issue. Bulk reprints of individual articles can be ordered. This publication is partially supported by Korea Research Foundation and the Korean Federation of Science and Technology Societies.
