“…Nowadays, energy crisis and environmental contamination have become two of the most serious issues on the earth due to rapid economic development and population growth. − Indeed, multifarious toxic organic compounds, including antibiotics, pesticides, hormones, dyes, and industrial organic intermediates, − are frequently detected in domestic water and natural water bodies, resulting in an enormously harmful effect on human beings and the ecological environment. − Hence, it is highly desirable to develop high-efficiency sewage treatment processes, in which toxic pollutants could be efficiently degraded into nontoxic small molecules, − even completely mineralized to CO 2 and H 2 O. , …”

Despite significant progress being made in the development of cobaltosic oxide or modified cobaltosic oxide nanomaterials in the degradation of organic pollutants, to our knowledge, there are only very few available reports on the crystal facet effect of Co 3 O 4 with different morphologies on peroxymonosulfate activation for oxytetracycline degradation. Herein, we first reported the synthesis of three kinds of Co 3 O 4 nanocomposites with various morphologies, including nanocubes (Co 3 O 4 -c), octahedron (Co 3 O 4 -o), and truncated octahedron (Co 3 O 4 -t), for activating peroxymonosulfate (PMS) in the degradation of oxytetracycline at 30 °C. The detailed physical characterizations illustrated that Co 3 O 4 -c, Co 3 O 4 -o, and Co 3 O 4 -t possessed a uniform morphology of nanocubes, octahedron, and truncated octahedron, with six {100} exposing facets, six {111} exposing facets, and a mixture of eight {111} and six {100} exposing facets, respectively. In particular, the optimal Co 3 O 4 nanocubes (Co 3 O 4 -c) presented the highest catalytic reactivity in the activation of PMS for OTC degradation, with 82.8% degradation efficiency and 46.4% mineralization rate at 30 °C. The DFT results exhibited that the ΔE total of PMS on Co 3 O 4 {100} exposing facets (−23.7 eV) was much lower than that of PMS on Co 3 O 4 exposing {111} facets (−17.2 eV), indicating that PMS activation was more likely to occur at the Co 3 O 4 {100} exposing facets, which was in good accordance with the above experimental conclusion. Overall, the explanation of the crystal facet effects on PMS activation proposes a research orientation for the synthesis of crystal engineering of heterogeneous catalysts on wastewater treatment.
