Ammonia pools in zeolites for direct fabrication of catalytic centers.

Reduction process is a key step to fabricate metal-zeolite catalysts in catalytic synthesis. However, because of the strong interaction force, metal oxides in zeolites are very difficult to be reduced. Existing reduction technologies are always energy-intensive, and inevitably cause the agglomeration of metallic particles in metal-zeolite catalysts or destroy zeolite structure in severe cases.

A Carbonylation Zeolite with Specific Nanosheet Structure for Efficient Catalysis.

Up to now, the member of zeolite family has expanded to more than 230. However, only little part of them have been reported as catalysts used in reactions. Discovering potential zeolites for reactions is significantly important, especially in industrial applications.

Product-oriented decomposition of lignocellulose catalyzed by novel polyoxometalates-ionic liquid mixture.

Lignocellulose was oxidatively decomposed in a newly developed polyoxometalates-imidazolium ionic liquid mixture. Aromatic compounds covering acids, esters, ketones, aldehydes, and phenols were selectively produced under various conditions. 4-Hydroxylbenzoic acid was dominatingly yielded under low temperature and high oxidant concentration.

Relationship between weight status and health-related quality of life in Chinese primary school children in Guangzhou: a cross-sectional study.

Background: To investigate the association between weight status and health-related quality of life (HRQOL) among pupils in Guangzhou, China.

Methods: The study comprised 5781 children aged 8-12 years from 29 schools. Height and weight were objectively measured using standardized methods, and BMI z-score derived using the age and sex specific WHO reference 2007 for 5-19 years.
