“…As the results show, further 10 Advances in Materials Science and Engineering increase in Ce and Zr loading reduces the yield of ethylene and propylene. is can be attributed to the increase in the amount of Ce and Zr oxides on the catalyst surface and the blocking of the catalyst cavities, preventing penetration of naphtha molecules into the catalyst cavities and preventing thermal catalytic cracking of Naphtha reactions [111][112][113][114][115].…”

In this paper, Ce and Zr modified commercial SAPO-34 and H-ZSM-5 catalysts were synthesized via a wet impregnation method and used as catalysts for the production of light olefins from naphtha. The synthesized catalysts were characterized using SEM, TGA, XRD, BET, and NH3-TPD. Thermal catalytic cracking of parent catalysts (SAPO-34 and H-ZSM-5) and modified catalysts with Ce and Zr on the production of light olefins from naphtha has been studied. The effects of different loading of Ce (2–8 wt.%), Zr (2–5 wt.%), and different temperatures on the yield of ethylene and propylene were also investigated. The yield of ethylene and propylene improved by 21.78 wt% and 23.8 wt%, respectively, over 2% Ce and 2% Zr on SAPO-34 catalyst. This is due to the higher acid sites on the surface of modified catalysts. It was found that H-ZSM-5 with 2% Zr loading has the highest yield of light olefins (40.4%) at 650°C in comparison with unmodified parent catalysts, while Ce loading has less effect on the olefin yield compared to Zr loading. Finally, simultaneous loading of Ce and Zr showed no effect on the light olefin yield owing to the significant decline of acid sites.

“… There are different methods for making albumin nanoparticles under mild environmental conditions. Albumin as a structural unit of nanoparticles [ 232 – 234 ], an acidic protein, is very soluble and stable. Albumin is a flexible molecule and easily deforms depending on the environmental conditions in which it is located and also by changing the binding of ligands and returns to its original state at the first opportunity with the help of disulfide bonds, and this property is an advantage.…”

“…In conventional lithium-ion batteries, the cathode electrode is made from a type of carbon powder, such as carbon black or activated carbon under various names such as Super P and Ketjenblack, which is used with a binder to bind the powder particles and the catalyst to increase speed [126][127][128][129][130][131]. Nanotechnology can be effective in removing the binder and using a method other than mechanical mixing [132][133][134][135][136][137].…”

In vehicles that require a lot of electricity, such as electric vehicles, it is necessary to use high-energy batteries. Among the developed batteries, the lithium-ion battery has shown better performance. This battery has an energy density of 10 equal to that of a lithium-ion battery and uses air oxygen as the active material of the cathode and anode like a lithium-ion battery made of lithium metal. The cathode used in these batteries must have special properties such as strong catalytic activity and high conductivity, and nanotechnology has greatly helped to improve the materials used in the cathode of lithium-air batteries. The importance of proper catalyst distribution and the relationship between the oxide product and the catalyst and the indirect effect of the ORR catalyst on the OER reaction is not present in the fuel cell. The maximum capacity of lithium-air battery theory using graphene under optimal electron conduction conditions and the experimental maximum obtained for graphene by optimizing the structure geometry, examples of structural engineering using carbon fiber and carbon nanotubes in cathode fabrication with the ability to perform the reaction properly while providing space for lithium oxide placement, are examined. This article describes the mechanism of this battery, and its components are examined. The challenges of using this battery and the application of nanotechnology to solve these challenges are also discussed.
