To enhance the electrocatalytic activity of heteroatom doped carbon for oxygen reduction reaction (ORR), high surface area and favorable porous structure are commonly required for providing sufficient accessible active sites. However, these features usually come with the severe carbon loss during pyrolysis and activation process. Herein, we report a facile self-terminated activation strategy for high-yield...
Co nanoparticle-encapsulated N-doped carbon nanotubes (Co@N-CNTs) are prepared as a Pt-free electrocatalyst for oxygen reduction reaction (ORR) via direct pyrolysis of a CoAl-layered double hydroxide (CoAl-LDH)/melamine mixture. The approach could bundle the following distinct features: (i) commercially available melamine as both carbon and nitrogen bi-functional sources; (ii) scalably prepared CoAl-LDH...
To develop cost-effective carbon-based sorbents used in gas-phase elemental mercury removal, the performance of commercial bamboo charcoal (BC) produced from renewable bioresource of bamboo and modified BC was investigated with a bench-scale fixed-bed reactor. The simple impregnation method was used to modify the BC using ZnCl 2 , NH 3 ·H 2 O and HNO 3 separately. BET,...
