Energy problems are a substantial concern in a global
society that
can be solved by replacing with sustainable energies. In recent years,
designing nanomaterials as photocatalysts that can produce chemical
energy with the utilization of infinite visible light energy became
a new solution for water treatment. In the present study, NiCo2O4@MOF-801 has been synthesized with multiple properties,
and then, a novel three-layer NiCo2O4@MOF-801@MIL88A
photocatalyst has been successfully synthesized to improve meropenem
degradation and Cr(VI) reduction. The prepared photocatalyst was characterized
by XRD, IR, XPS, TEM, SEM, TGA, BET, EIS, PL, and UV–vis. According
to the structural and optical analysis performed, the interaction
between the components formed a heterojunction structure that prevented
the recombination of charge carriers and increased the photocatalytic
performance. Photocatalytic simulation tests also proved the reduction
of chromium and degradation of antibiotics to find the optimal heterogeneous
performance. As a result, the NiCo2O4@MOF-801@MIL88A
composite can completely reduce Cr(VI) in 45 min, which is strongly
preferable to any pure component’s performance. Overall, this
work offers a low-cost but high-efficiency material that can remove
organic and inorganic contaminants from water.
