| dc.description.abstract | The synthesis of atomic-scale catalysts is a blooming field, and these replace the conventional nanocatalysts due to their high atom utilization, selectivity, and unique catalytic activity. Metal-organic frameworks (MOFs) serve as promising precursors for the synthesis of single-atom catalysts (SACs). This study focused on the synthesis of SACs on nitrogen-doped hollow carbon by using MOFs and MOF composites followed by pyrolysis. The synthesis of two SACs namely rhodium SACs (Rh SACs) and cobalt SACs (Co SACs) by different methods, their characterization, and catalysis was explored. Rh SAC synthesized in this work hydrogenates nitroarenes with high consumption and high selectivity. Moreover, Co SAC did little or no hydrogenation of the nitroarenes. Further applications of these SACs were explored by employing them in oxygen reduction reaction (ORR), NO abatement, and Fenton-like catalysis. Moreover, the synthesis of two types of hollow nanoboxes (HNB) namely HNB-1 and HNB-2; using MOFs and MOF composites, their characterization and applications were also investigated. HNB-1 was used to make electrode supercapacitors and it showed comparable activity to activated carbon. Further attempts were made to use HNB-2 as a fluorescence sensor. Finally, several ideas on synthesising SACs and HNBs were proposed as a part of future work. | en_US |
