Welding partially reduced graphene oxides by MOFs into micro-mesoporous hybrids for high-performance oil absorption.

ABSTRACT: Partially reduced graphene oxides (PRGOs) with a small number of COOH groups remaining at the edges were interlocked by UiO-66-NH₂ nanoparticles into hierarchical porous hybrids (PRGO@UiO-66-NH₂) during the synthesis of UiO-66-NH₂ in the presence of PRGOs, in which the UiO-66-NH₂ nanoparticles provide micropores and the interlocked PRGO skeletons provide mesopores. The peak intensity of the functional groups on the PRGO@UiO-66-NH₂ hybrids decrease greatly when compared with the GO@UiO-66-NH₂ hybrids and the UiO-66-NH₂ nanoparticles, and the number of -COOH at the edge of the PRGOs are approximately 6.3% after reduction, which is confirmed by the FT-IR and XPS results. When the PRGO@UiO-66-NH₂ hybrids we
