“…Also their catalyst performances were demonstrated using conventional heating at higher temperatures than our current report. Coupling involving chloroarenes (TOF ∼1575 h −1 , this work) showed significant enhancement from previous reports (TOFs ∼6 h −1 for, ∼0.5 h −1 for and <0.1 h −1 for), Entries 9 and 10, Table reported similar catalysts by name with a different synthesis methodologies, with catalyst performance being investigated in 3:1 water‐PEG mixture and 1:1 ethanol‐water mixtures respectively, showing lesser activity (TOFs) than that of the current work (entry 11, Table ). Also, the use of microwave irradiation under aerobic conditions added value to the presently described work.…”

“…reported Suzuki‐Miyaura couplings using Pd‐nanoparticles on graphitic carbon nitride in water‐PEG (3:1) medium but with much less activity (TOFs in the range ∼ 240 h −1 ) using conventional heating between ambient to 100 °C. Similar catalyst Pd/gC 3 N 4 synthesized using photodeposition method was reported by Sun et al . for Suzuki‐Miyaura couplings in 1:1 ethanol‐water mixtures with low TOFs.…”

Microwave assisted Suzuki cross‐coupling of aryl halides with different arylboronic acids were obtained using nano‐Pd/gC3N4 composite as catalyst in water as solvent under aerobic conditions. Catalyst was found to be highly efficient exhibiting high TOFs ∼ 12,000 h−1 for a spectrum of substituted reactants exemplifying unique green chemistry approach combining efficient reusable catalysis in water in presence of air and using microwave irradiation as alternative heating mode.

“…[38] It should be noticed that this was also observed in the case of the Pd/g-C 3 N 4 catalyst. [29,39] Figure 5(A) shows Ti K-edge XANESs pectra of 1.0Ti-g-C 3 N 4 , Pd/1.0Ti-g-C 3 N 4 and reference compounds (anatase TiO 2 powder). Anatase TiO 2 reference showed well-definedp re-edge peaks from 4960 to 4975 eV,w hich is due to the transitions from the 1s core level of the Ti atom to three different kindso f molecular orbitals (1t 1g ,2 t 2g ,a nd 3 eg )o fT iO 2 having octahedral geometry.…”

Pd nanoparticles (NPs) supported on Ti-doped graphitic carbon nitride (g-C N ) were synthesized by a deposition-precipitation route and a subsequent reduction with NaBH . The features of the NPs were studied by XRD, TEM, FTIR, XPS, EXAFS and N -physisorption measurements. It was found that the NPs had an average size of 2.9 nm and presented a high dispersion on the surface of Ti-doped g-C N . Compared to Pd loaded on pristine g-C N , the Pd NPs supported on Ti-doped g-C N exhibited a high catalytic activity in formic acid dehydrogenation in water at room temperature. The enhanced activity could be attributed to the small Pd NPs size, as well as the strong interaction between Pd NPs and Ti-doped g-C N .

“…Metal NPs have been employed in fabricating biohybrid catalysts cooperatively with enzymes. [4a,12] Due to the 2D conjugated planes packed together with tris‐ s ‐triazine repeating units facilitating the binding of exotic atoms into its matrix, C 3 N 4 can serve as a superior scaffold for stabilizing metal atoms and/or NPs, such as Pd, Pt, Ag, Au, Cu, and alloys . Because of the large amount of N atoms, exceptional activity can be achieved due to the high ratio of low‐coordinated metal atoms in these composite materials.…”

equilibrium is shifted, usually resulting in a higher conversion of substrates. Today, immobilizing chemo-and biocatalysts on solid materials to fabricate heterogeneous biohybrid catalysts for cascade reactions has attracted growing interests because of the easy products' separation and simplified catalysts reuse. On the other hand, because of the co-immobilization of different catalysts on the same support, diffusion limitation of intermediates between active sites is reduced, which promotes the overall reaction efficiency in the one-pot process. To date, mesoporous silica, [4] metal-organic frameworks (MOFs), [5] reduced graphene oxide, [6] and polymeric matrices [7] have been utilized as supports for preparing biohybrid catalysts. It was found that intrinsic properties of these supports have a significant impact on the stability and distribution of immobilized chemocatalysts, while the compatibility between carriers and enzymes still remains a concern since enzymes are vulnerable in in vitro environment. Therefore, the judicial selection of solid supports is vitally important, and the task of seeking for new solid supports for developing biohybrid catalysts featuring new functions continues.In the past decade, carbon nitride (C 3 N 4 ) has emerged as a promising material for its outstanding performances in photocatalysis [8] and electrochemistry. [9] Besides, it has been also utilized for bioimaging and biomedical applications, where its good biocompatibility was verified through various methods,The exploration of effective platforms for immobilizing chemo-and biocatalysts to develop biohybrid catalysts is an attractive subject of practical interest. In this work, carbon nitride (C 3 N 4 ) is used for the first time as a platform for the immobilization of metal catalyst (Pd nanoparticles) and biocatalyst (Candida antarctica lipase B, CalB) in a facile manner to prepare biohybrid catalyst. The optimal biohybrid catalyst inherits the intrinsic performance of both Pd nanoparticles and CalB, and shows high activity in the one-pot cascade reaction converting benzaldehyde to benzyl hexanoate at room temperature. With this proof of concept, it is expected that C 3 N 4 can be utilized for immobilizing more types of chemo-and biocatalysts for perspective applications.
