...Haibing Liu; Chen Chen; Yan Shen A composite catalytic system composed of choline chloride, p-chlorophenol, and zinc acetate was developed for the efficient glycolysis of waste polyethylene terephthalate ( PET ). Under optimal conditions (185°C, 4 h, 2.5 wt% catalyst), PET was depolymerized...

...Mingzhu Sun; Linlin Zhao From the perspective of green chemistry, biomass-derived catalysts were prepared using waste oyster shells as raw materials. The oyster shell-derived catalyst obtained at a calcination temperature of 950°C exhibited remarkable catalytic activity. This catalyst was used...
