“…2,5 Recently, a lot of work has been done on the catalysts to increase the conversion of 1,2-DCE and the selectivity of VCM at low reaction temperature. [6][7][8][9][10][11] Though they have drawn considerable interest in this eld, until now, they are still far from industrialization. 12 Therefore, efforts are ongoing to produce metal-free, environmentally friendly, and more efficient materials as catalysts for industrial green chemical processes to date.…”
