Zn2 fe3 la3 and ce3 ion exchanged Mapo 36 characterisation and Catalytic performance

Abstract

Catalysis plays vital role in not only increasing the rate of a chemical newlinereaction but also minimizing adverse impact on the environment One of the newlineforemost challenges of chemical industries is the need for alternative newlineproduction technologies that are cleaner safer and eco friendly Atom newlineeconomy is a significant parameter in order to design a chemical reactor newlineespecially in the mass production of chemicals In the past few decades green newlinechemistry has demonstrated how fundamental heterogeneous catalysts can newlineprotect human health and environment in an economically beneficial manner newlineThe surface area of a catalyst is another factor which increases catalytic newlineactivity by exposing more active centers to the adsorbed reactants thereby newlineincreasing the rate of a reaction Lewis and Brönsted acidities in the catalysts newlineare two fundamental active centers in most of the solid acid catalysts Among newlinethe heterogeneous catalysts zeolites zeotype and mesoporous molecular newlinesieves with metal incorporation in the lattice have attracted much attention newlinebecause of their remarkable catalytic activity under mild reaction conditions newlineCompared to zeolites aluminophosphate molecular sieves AlPOs possess a newlinelarger variety of acid sites and broader acid sites distribution newline newline
