“…In recent years, research on zeolites with porous structures has gradually attracted widespread attention. Currently, zeolites with porous structures have been used in various catalytic reactions, such as alkane cracking, , ethanol dehydration, , reduction of NO x , − and treatment of volatile organic compounds (VOCs), , among other processes. On the basis of the good performance of loaded pore-structured metal oxide materials in the catalytic oxidation of soot, loaded zeolite molecular sieves are also increasingly used for this purpose.…”

Because of their special physicochemical properties, pore-structured metal oxide catalysts are widely used in environmental catalysis, energy chemicals, fuel cells, medicine, and other related fields. In recent years, these oxides have also been increasingly studied in the catalytic purification of diesel engine exhaust gases. In this paper, the research progresses of preparation methods of porous metal oxide catalysts and their application in the catalytic purification of diesel engine exhaust were reviewed. The advantages and disadvantages of different methods for the synthesis of porous metal oxide catalysts were elaborated, as well as the mechanism comparison of different types of porous metal oxide catalysts in catalytic purification of diesel engine exhaust pollutants. Finally, the current issues on the preparation of porous metal oxide catalysts and their development trends in application of diesel engine exhaust purification were summarized and discussed. The pore-structured metal oxide catalysts are beneficial for improving the contact efficiency between catalysts and pollutants, which can enhance the catalytic purification efficiency of catalysts. Meanwhile, the intrinsic activity is the most fundamental factor for determining their catalytic activity except for porous structure effects. In addition, this paper can help researchers to deeply understand the important effect of porous metal oxide catalysts in the treatment of diesel engine exhaust pollutants and provide theoretical guidance for the design and development of high-efficiency catalysts.

“…Apart from the well‐known shape selectivity features of zeolite catalysts, there are a variety of benefits, ranging from clearly identified secluded areas with adjustable acidity to a controlled polarity within the zeolite. It is worth noting that, despite the size of the channels, which decelerates diffusion (resulting in slower reaction rate and deactivation), rapid improvements are underway to establish hierarchical zeolites, nanocrystalline and nanosheet zeolites, as well as to develop large‐pore zeolites 131‐134 . However, because of the need for sophisticated models and multistep methods, the synthesis of these materials is frequently prohibitively expensive.…”

Bioethanol, synthesized through the valorization of biomass resources, is of great importance to many industries. As bioethanol has become more abundant and its price has decreased, it has become an attractive candidate for application as a base material for the synthesis of a variety of petrochemicals and fuel through catalysis. In this article, a comprehensive review of the catalytic conversion of bioethanol into hydrocarbons, including olefins and gasoline, is presented. In addition, developments and potential research opportunities in the field of bioethanol catalysis are provided to enhance bioethanol conversion. According to the findings of the study, despite significant progress in bioethanol conversion, further research is needed to address several challenges that will enable improved biofuel and chemical production.
