“…28,29 However, the large drawback is the di culty in separating the catalyst and product. Thus, various heterogeneous catalysts have been developed, [30][31][32][33][34][35] most of which contain a noble metal such as Au, 30 Rh, 31 or Pd. [33][34][35] New heterogeneous catalysts that are inexpensive and highly e cient are strongly demanded.…”

Topological materials have received much attention because of their intriguing nontrivial physical properties. Their robust topological surface states (TSSs) afford a stable electron bath that facilitates surface reactions, which has been successfully used to promote reactions on transition metals (TMs). As emergent heterogeneous catalysts, TSS-TMs have introduced new catalytic effects. However, the direct application of TSSs to catalysis has thus far remained elusive. In the present study, we show that Bi2Se3, one of the most representative topological insulators, functions as an excellent catalyst for the oxidative carbonylation of amines with CO and O2 to synthesize urea derivatives, showing superior activity compared with conventional TM-containing heterogeneous and homogeneous catalysts. For example, when Bi2Se3 nanoparticles were used as catalysts, the carbonylation of butylamine was completed in 4 h at 20 °C with a yield of 99%, whereas noble-metal-based catalysts do not function at such a low temperature. In addition, the turnover frequency (TOF) of Bi2Se3 (41 h−1) is five times greater than that for BiSe, which has a crystal structure similar to that of Bi2Se3 but with substantially weakened TSSs. Density functional theory calculations further reveal that the TSSs facilitate the activation of O2 through a triplet-to-singlet spin-conversion reaction, which is the key step for the generation of urea derivatives from amines. These findings indicate a new application area of topological insulators in heterogeneous catalysis.

“…Currently, conventional processes for the synthesis of urea derivatives involve the use of highly toxic phosgene, causing potential ecological and/or toxicological risk. [ 15,16 ] Accordingly, several alternatives to phosgene process have been developed such as carbonylation, [ 17–19 ] Curtius rearrangement of azides, [ 20 ] or transamination of carbonates, [ 21 ] with corresponding amines to produce urea products. However, these protocols suffered from several drawbacks of using toxic gas, a limited range of reagents, or precious metal‐based catalysts.…”

From the perspectives of environmental and economic benefits, the catalytic fixation of CO 2 is considered one of the best pathways to mitigate the CO 2 concentration. Towards this end, several extensive efforts to convert CO 2 into commodity chemicals and fuels have been undertaken over past decades. [4] For example, several useful molecules including methanol, carbonates, heterocycles, carboxylated compounds, etc., could be synthesized from the catalytic valorization of CO 2. [5-7] Although being considered as a cheap and abundant source of carbon, the thermodynamic inertness and kinetic limitation of carbon dioxide has still remained an impediment to the activation of this molecule. [8] 1,3-Disubstituted ureas (DSUs) are an important class of carbonyl compounds, which are widely used as intermediates in the production of fine chemicals, agrochemicals, and bioactive molecules. [9-12] Besides, DSUs can be readily transformed to corre

“…The doping of carbon materials with heteroatoms (B, N, O, P, and S) broadens the fields of the application of carbon materials. Heteroatom-doped carbon materials have attracted much attention in the field of heterogeneous catalysis owing to their tunable surface structures and electronic properties [1][2][3][4][5][6][7][8][9][10][11][12]. The influence of N-doping to carbon materials on their catalytic performance has been extensively studied [13][14][15].…”

Selective Hydrogenation of 3-Nitrostyrene over a Co-promoted Pt Catalyst Supported on P-containing Activated Charcoal

A series of Co-modified Pt catalysts supported on P-containing activated charcoal were studied for the selective hydrogenation of 3-nitrostyrene (NS) to 3-aminostyrene (AS). The addition of Co decreased the rate of hydrogenation but enhanced the selectivity to AS, being 92% at nearly 100% conversion over an optimized catalyst. The high AS selectivity should result from the configuration of NS adsorption on the catalyst, which occurs preferentially with its -NO2 group on the Pt–POx interface layer over the surface of supported Pt particles. The formation of such a Pt–POx area is promoted by the Co additive.
