A palladium-based catalyst supported on amine-functionalized magnetite nanoparticles was successfully prepared by a facile one-pot template-free method combined with a metal adsorption–reduction procedure. The catalyst was characterized by TEM, XRD, XPS, FT-IR and VSM. The catalyst afforded fast conversions for various aromatic nitro and unsaturated compounds, and with a turn-over frequency (TOF) of 83.33 h⁻¹ under a H₂ atmosphere in ethanol, even at room temperature. Furthermore, it was found that the catalyst showed a high activity for the Heck reaction, affording over a 93% yield in all the cases investigated. Interestingly, the novel catalyst could be recovered in a facile manner from the reaction mixture and recycled eight times without any significant loss in activity.

The ZIF-67 derived cobalt telluride encapsulated on nitrogen-doped carbon nanotubes frameworks (CoTe ₂ @NCNTFs) was synthesized, which exhibits remarkable electrocatalytic performances for overall water splitting.

Hollow bimetallic cobalt-based selenide polyhedrons M x Co _1−x Se ₂ were successfully synthesized by a simple solvothermal strategy using bimetallic MOFs as template. This catalyst exhibits excellent electrocatalytic performance for overall water splitting.

In the present work, MoS₂ quantum dots (MoS₂ QDs) decorated on reduced graphene oxide (RGO) as highly effective electrocatalysts were synthesized by a facile sonication method for the hydrogen evolution reaction (HER).
