Todays, the heteroatom-doped mesoporous carbon resulting from Metal-Organic Framework (MOF) has attracted the substantial consideration in various filed especially in the heterogeneous catalytic protocols due to their adaptable features. These materials have a high Specific Surface Area (SSA), which offers copious activated sites for the catalytic activity. The mesoporous nature also simplifies the effectual mass transfer, thereby amplifying the overall catalytic procedure. In this study, a highly effective Zr@NC-T samples were synthesized via pyrolyzing a composite of g-C3N4 and UiO-66. The mesoporous structure of Zr@NC-T, revealed a desired SSA varying from 591.38 to 404.26 m2.g−1 due to its surface defect and disorder. Among the synthesized catalysts, Zr@NC-700 (pyrolyzed at 700 °C) exposed preferred catalytic proficiency in the selective oxidation of BnOHs to BnCHO due to its higher surface defect which is caused the higher SSA and structure defect. Furthermore, the Zr@NC-700 catalyst as well proved the acceptable chemical stability due to its reusability. [Display omitted]
