Deepening continuously for muonic catalysis agent research, rises the correlative study of " class monoatomic metal catalyst " gradually.With monatomic catalysis
Agent is different, and this " class is monatomic " catalyst can provide and instead since there is a synergy between for its adjacent metal atom
The more matched active site distribution of object molecular dimension is answered, thus the energy barrier of certain reactions can be effectively reduced, forms new reaction road
Diameter has the advantages that monatomic catalyst cannot compare.
Tsinghua University Li Yadong academician is by by Ru3(CO)12Molecule is as presoma and is dispersed in ZIF zeolite molecules
Sieve cage in, after through pyrolysis form the uniform Ru stable by N ligand3Cluster, produce has unique knot at lower cost
The Ru of structure and excellent catalytic performance3/ CN catalyst.The results showed that Ru3/CN (4320 h-1) TOF ratio Ru1/
The monatomic catalyst of the CN (h of TOF=416-1) about 10 times high.But the growth of ZIF is amplified easily to condition responsive, and with system
Cause presoma dispersion uneven since mass transfer is limited.
The Lu Junling of China Science & Technology University carries out bottom layer treatment to graphene using atomic layer deposition method and generates suitably
Nucleation site, and deposit with this that first Pt is monatomic, and the Pt atom come on second batch can be deposited selectively
In these Pt1 On site, Pt that is uniform and isolating each other is formed2Diatomic structure.Due to there is electricity between two Pt atoms
Son synergistic effect, so that being in the Pt atom pair ammonia borine and H on top2Absorption ratio Pt1It is monatomic weaker, specific table
It is now Pt2Catalyst B atom when being catalyzed ammonia borane hydrolysis dehydrogenation reaction is remaining less on Pt atom, to catalyst
Poisoning effect it is small, therefore by Pt2The reaction rate of diatomic catalyst is Pt1Under monatomic catalyst
17 times.But the preparation method condition is harsh, more demanding to instrument and equipment and expensive, and synthesis cost is high.
