N-doped biochar synthesized by a facile ball-milling

After N doping, the surface O in ball-milled biochar decreased 20.6–30.5%, further suggesting that O-containing functional groups were crucial to the N doping by the ball milling. It has been reported that ball milling can introduce O-functional groups to the surface of biochar [25],[33] .

Nitrogen-doped graphene by all-solid-state ball-milling

The ball-milling induced doping of nitrogen atoms to the graphene sheets is accounted for the enhanced power performances owing to the improved electronic conductivity and Li-ion absorption capability it offers. All-solid-state ball-milling graphite with urea provides a promising method for preparing NGNS as high performance anode carbon

Influence of Ball Milling, Cold Rolling and Doping (Zr

In this paper, we found that the first hydrogenation properties of TiFe alloy can be significantly improved by ball milling, cold rolling and doping. The samples by ball milling for 60 min and doped with (Zr + 2Cr) as additive showed a faster hydrogenation kinetics and the sample cold rolled for 5 passes showed the highest hydrogen capacity.

Easy method to prepare N-doped carbon nanotubes by ball

Melamine or urea can be successfully used as nitrogen precursor for the N-doping of carbon nanotubes by ball milling; nevertheless, the samples doped with melamine present larger N content. The use of solvent during ball milling revealed a negative effect for the introduction of N-functionalities, regardless of the precursor used.

As indicated in the results, biochar feedstocks, pyrolysis temperatures, and treatment by N doping and/or ball milling are significant factors for determining the CO 2 adsorption capacities. It showed that the CO 2 adsorption capacities (52.5 and 49.2 mg g −1) of BMHC600-N (ball-milled, N-doped hickory chips prepared at 600 °C) and BMHC450-N
