We synthesized polyethylene (PE), poly(ethylene-co-1-decene), poly(ethyleneco-p-methylstyrene) and poly(ethylene-ter-1-decene-ter-p-methystyrene) using a rac-Et(Ind)2ZrCl2 metallocene catalyst and a methylaluminoxane cocatalyst system. The materials were characterized using nuclear magnetic resonance spectroscopy and Fourier transform infrared spectroscopy. We compared and studied the kinetics,...
Solar-driven water splitting to produce hydrogen may be an ideal solution for global energy and environment issues. Among the various photocatalytic systems, platinum has been widely used to co-catalyse the reduction of protons in water for hydrogen evolution. However, the undesirable hydrogen oxidation reaction can also be readily catalysed by metallic platinum, which limits the solar energy c...
Loading of cocatalysts through photodeposition has been considered as one the most promising methods to improve photocatalytic activities semiconductors, because advantages intimate contact, easy preparation, and site-directed loading. While extensive efforts have made characterize after synthesis, growth kinetics during is largely a black box, thus leading relatively empirical optimizations on...
