DOI: 10.1016/j.mtphys.2020.100312
Abstract: Abstract Two-dimensional (2D) nitrogenated holey carbon materials are promising non-precious photocatalysts for clean energy production. However, their efficiency is limited by the fast electron-hole recombination and lack of active sites. To overcome these drawbacks, here… read more here.
