Special Issue Information

Dear Colleagues,

A catalyst is a material that changes the path of a chemical reaction without itself being expended. At present, almost 90% of chemical products are produced with the help of catalysts. Heterogeneous catalysis is one of the main pillars of the chemical and energy industries. The construction of active and robust heterogeneous catalytic systems is an important goal that includes new catalyst synthesis methods, the in situ exploration of mechanisms of catalyst synthesis and catalytic reactions, the novel design of catalytic reactors, and the development of new catalytic reactions in the field of conventional thermal catalysis, photocatalysis, electrocatalysis, etc.

This Special Issue entitled Construction of New High Efficiency Heterogeneous Catalytic System seeks high quality studies focusing on the latest novel advances in heterogeneous catalysis science & technology. Topics include, but are not limited to:

  • Surface and interface catalysis of nano and cluster structures;
  • High-efficiency catalytic conversion of organic molecules;
  • Catalytic hydrogenation and oxidation reactions;
  • Creation of porous catalytic materials such as alumina and silica;
  • In situ dynamic characterization technology and catalytic mechanism research;
  • Solar energy photocatalytic and electrocatalytic water splitting to produce hydrogen;
  • Designing high-efficiency hydrogenation and dehydrogenation catalysts for hydrocarbons;
  • Catalytic system for recyclable polymer synthesis and waste plastic recovery;
  • High value-added catalytic conversion of renewable biomass sources;
  • Electrocatalytic conversion and degradation of small organic molecules.

With the increasing attention to light oil, the catalytic cracking process of heavy oil is being vigorously developed. The silicon hydroxyl groups on the surface of mesoporous silica materials can be used as weak acid centers to preliminarily crack heavy oil macromolecules. Herein, a strategy of introducing titanium into a silica skeleton for modification is proposed to increase active sites, as well as improve the hydrothermal stability. After titanium modification, the mesoporous silica material has more weak acid sites, and shows better ability in deep cracking heavy oil. Notably, when the content of titanium doping is 2%, the CT(2) catalyst exhibited the best high-temperature hydrothermal stability, which can be used as a suitable heavy oil catalytic cracking catalyst. This kind of titanium-modified mesoporous silica material shows great application prospects in heavy oil catalytic cracking, which may provide a novel idea for subsequent development. Full article
