Heterogeneous Catalysis means that the reacting species and the catalyst do not have the same phase. A mathematical model for such a reaction has to take into account as well the complex kinetic processes and the spatial coupling. Depending on how strong the reactants are bound to the surface of the catalyst, the diffusion coefficients may vary by orders. Diffusion does not only smoothen the co...

Heterogeneous catalysts are promising for the transesterification reaction of vegetable oils to produce biodiesel and have been studied intensively over the last decade. Unlike the homogeneous catalysts, heterogeneous catalysts can be easily separated from reaction mixture and reused for many times. They are environmentally benign and could be easily operated in continuous processes. This revie...

Metallic nanoparticles finely dispersed over oxide supports have found use as heterogeneous catalysts in many industries including chemical manufacturing, energy-related applications and environmental remediation. The compositional and structural complexity of such nanosized systems offers many degrees of freedom for tuning their catalytic properties. However, fully rational design of heterogen...

Annulation of internal alkynes with functionalized aryl halides is a versatile and useful method for the synthesis of a wide variety of carboand heterocycles (Fig. 1). To date, many homogeneous transition metal-based catalytic systems have been developed for this transformation. Although homogeneous catalysis have many advantages, difficulties in separation and recovery of the catalyst and prod...

The pharmaceutical industry currently experiences a trend towards continuous manufacturing as there are many advantages, including better control of process conditions, effectively eliminating batch-to-batch variability, and the lack of scale-up problems, since even bench-top continuous systems can produce the desired quantities required in the pharmaceutical or fine-chemicals industry. We pres...

A porous molecular crystalline solid based on amide-containing Pd(II) triangles was created for size-selective heterogeneous catalysis of the Knoevenagel condensation reaction.

The past three decades have witnessed significant development of metal-organic frameworks (MOFs) for heterogeneous catalysis. At the crossroads development, fundamentals on design MOF-based catalysts along with specific uniqueness MOFs catalysis are summarized in this Comment. Moreover, bottlenecks limiting further and opportunities moving field forwards discussed.

Heterogeneous catalysis lies at the heart of chemical and fuel manufacturing industries hence is a cornerstone many economies.

A simple and effective strategy is developed to realize visible light-driven heterogeneous asymmetric catalysis. A chiral organic molecule, which only has very weak catalytic activity in asymmetric α-alkylation of aldehydes under visible light, is utilized as the ligand to coordinate with different types of metal ions, including Zn2+, Zr4+, and Ti4+, for construction of crystalline metal organi...

Rh-based heterogeneous catalysts generally have limited selectivity relative to their homogeneous counterparts in hydroformylation reactions despite of the convenience of catalyst separation in heterogeneous catalysis. Here, we develop CoO-supported Rh single-atom catalysts (Rh/CoO) with remarkable activity and selectivity towards propene hydroformylation. By increasing Rh mass loading, isolate...
