In this work, we have synthesized a covalent organic polymer CPEP that exhibits high thermal and chemical stability, N-rich backbone, and spherical morphology that provide high surface-to-volume ratios for uniform confinement of Ni nanoparticles. Subsequently, the synthesis of the hybrid material Ni@CPEP was validated with various physicochemical characterizations and utilized as a potential catalyst for the degradation of vile organic dyes named Congo red, methylene blue, and methyl orange. The kinetic parameters affirmed its good catalytic response against all the dyes; in addition, thermodynamic parameters revealed the nonspontaneous and endothermic nature of degradation. As far as reusability is concerned, Ni@CPEP was reported as highly reusable with consistent performance in terms of reaction rate and stability, which is attributed to spherical morphology and uniform confinement of NPs.
