Special Issue Information

Dear Colleagues,

Mesoporous materials are a kind of porous materials with pore size between 2 and 50 nm. Due to the high specific surface area and abundant pore channels for mass transfer, mesoporous materials have attracted the long-term interest and attention of scholars in the field of materials and chemistry. In particular, the mesoporous nanostructured materials are excellent supports for loading and dispersing noble metal nanoparticles, sub-nano clusters, and even single atoms to catalyze many chemical processes, such as water–gas shift reaction, selective hydrogenation, steam reformation for H2 evolution, CO oxidation reaction, and so on. Therefore, it is highly desirable to develop mesoporous nanostructured materials for heterogeneous catalysis.

The aim of the current Research Topic is to cover promising, recent, and novel research trends in the mesoporous nanostructured materials for heterogeneous catalysis. Areas to be covered in this Research Topic may include, but are not limited to,

(1) new methodologies for preparing highly efficient mesoporous nanostructured materials;

(2) novel mesoporous-materials-supported metal nanoparticles for heterogeneous catalysis;

(3) novel mesoporous-materials-supported sub-nano clusters for heterogeneous catalysis;

(4) novel mesoporous-materials-supported atomically dispersed species for heterogeneous catalysis;

(5) novel unsupported mesoporous nanostructured materials for heterogeneous catalysis; and

(6) reviews on mesoporous nanostructured materials for heterogeneous catalysis

To clarify the Ni species of NiO/SiO2-Al2O3 catalysts that are active for ethylene oligomerization, 18 types of NiO/SiO2-Al2O3 were prepared using three Ni-loading methods (i.e., ion-exchange, impregnation, and homogeneous precipitation), with different Ni-loadings (1–20 wt%), and examined with respect to their structure and catalytic activity for ethylene oligomerization. Characterized by N2 adsorption, powder XRD, FE-SEM, H2-TPR, NH3-TPD, and C2H4-TPD showed that Ni species in the catalysts prepared by ion-exchange were mainly ion-exchanged Ni cations. In contrast, Ni species in the catalysts prepared by impregnation were a mixture of ion-exchanged Ni cations and NiO particles, and those in the catalysts prepared by homogeneous precipitation were all NiSiO3 particles. Catalytic-reaction tests at 300 °C and 0.1 MPa revealed the following: the ion-exchanged Ni cations showed the highest C2H4 conversion rate; the NiSiO3 particles showed a moderate reaction rate; and the NiO particles were not active for ethylene oligomerization. We concluded that the high catalytic activity of the ion-exchanged Ni cations was a result of their high dispersion and medium-strength acidity, which together promoted the adsorption and activation of ethylene on, and the desorption of oligomerization products from, the catalyst.
