Dehydrochlorination of 1,2-dichloroethane (1,2-DCE) is an important oil-based way for the industrial production of vinyl chloride monomer (VCM), but has proved to be plagued by a high operating temperature and low efficiency. Therefore, environmentally friendly and metal-free catalysts are in high demand for green chemical processes. In view of the stronger electronegativity of borazine (B3N3) and convenience of constructing a two-dimensional structure because of the coplanarity of B3N3, the acetenyl group, and the benzene ring, herein, we report a novel controllable B3N3doped activated carbon (B,N-ACs) synthesized using B3N3-containing arylacetylene resin for dehydrochlorination of 1,2-DCE. The result is activated carbon loaded with B3N3-doped carbon nanosheets on the surface due to the B3N3-containing arylacetylene resin grown on the surface of activated carbons. The B,N-ACs deliver excellent catalytic performance, with a 1,2-DCE conversion of ~92.0% and VCM selectivity over 99.9% at 250 °C, significantly higher than that of the current catalysts in the industry. The results further verified that pyridinic-N and the internal B3N3play significant roles in this catalysis. The new green, metal-free B,N-ACs with excellent catalytic efficiency make it a promising catalyst for dehydrochlorination of 1,2-DCE to produce VCM.

Recycling: A self-contained procedure for the recycling of BNH-waste, based on the three major steps: polymer break-up, amine supported catalytic hydrodehalogenation of boron halogens, and the base exchange in borane amine adducts, is developed (see picture). Beyond the original task of recycling spent ammonia borane, the process provides a new means to produce borohydride species efficiently, by the direct use of molecular hydrogen. Copyright

Boron nitride (BN) porous samples have been prepared in order to be used as noble metal catalyst support from various molecular precursors, using classical thermal methods to expand and preceramise the precursors. Three types of precursors have been teste
