“…1 Homogeneous rhodium complex catalysts are efficacious [2][3][4][5] but expensive and not easy to recover and reuse. For separation, immobilized or supported Rh, [6][7][8][9][10] usually assisted by phosphorus-containing ligands, and non-precious metal catalysts have been studied.…”

“…Type of catalyst supports play important roles in both activity and mechanical strength of catalysts, since they influence not only the morphology and dispersion of catalyst particles but also the activity of catalysts . Many studies of graphene oxide (GO) as catalyst support, which is prepared by chemical oxidation of natural graphite followed by exfoliation, seems to be more fascinating due to its abundant functional groups, including COOH and OH, as well as its unique 2D structure . Zhang et al reported that GO can probably provide efficient nucleation sites and enhance the MOFs growth, while offered higher dispersive forces of MOFs .…”

“…Heterogenization of metal complexes may provide a significant improvement in this aspect. Different approaches, broadly classified as “biphasic catalysis” and “solid‐supported catalyst” . The prime requirement for these catalysts is the stability of the complex in the heterogenized phase, which ensures that it does not leach into the noncatalyst liquid phase during the course of a reaction, while retaining the high activity, selectivity, and original configuration of the catalytic complex.…”

“…Various attempts were made to heterogenize some of the industrially relevant homogeneous catalysts for application to different catalytic reactions including hydroformylation. Although the techniques for heterogenization onto solid supports viz anchored catalyst, polymer‐bound catalyst, encapsulated catalyst, supported liquid phase catalyst, (SLPC) supported aqueous phase catalyst (SAPC), supported ionic liquid phase catalyst (SILP), biphasic catalysts using water‐soluble metal complexes of sulfonated, or fluorinated phosphines ligands, gave active catalysts; they were plagued with problems like leaching and deactivation of the catalysts. Although these concepts have drawn interest, with the exception of aqueous‐biphasic catalysis no other approach has been found to be commercially attractive, due to issues of catalyst leaching, catalyst product separation, and poor activity.…”
