Pan Xiulian from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences has revealed how the ...

The figures show two different situations with Brønsted acid sites in zeolites. The top figure shows a pair of such acid sites in the large cage (supercage) of zeolite Y. The conversion of such a ...

The rationale was to alter the distribution and composition of acid sites in the catalysts. Two types of acid sites are present in Zeolites; Brønsted acid sites (proton donors), and Lewis acid sites ...

Surface acid site characterisation is an essential step for the design, development, and quality control of successful zeolite-based catalysts. Temperature programmed methods (TPX) provide fast, ...

Heteroatoms work as active sites in zeolite frameworks and their distributions are crucial for selective catalytic reactions. However, their precise atomic sites have not been identified yet. This ...

After calcination to remove the organic template and triple nitric acid washing ... flexible zeolite framework obviously lowered the dehydrogenation barriers at isolated cobalt sites due to ...

JIAO Feng and Prof. PAN Xiulian from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences has revealed how the accessibility of zeolite acid site plays a crucial role ...
