3.2. Physicochemical Characterization of AC Samples Typical SEM images of the AC-N samples are given in Figure S1. The SEM images demonstrate irregular porous structure typical for AC materials. No clear difference in the structure of samples activated at different temperatures was detected. Also, we did not detect any visible difference in terms of structures between AC-N and AC-C-800 samples, prepared from sucrose and citric acid mixtures.

The electrocatalytic conversion of CO to energy-rich chemicals or energy vectors is a highly challenging approach to cope with an ever increasing demand for energy storage and valorization of renewable resources. Herein we report on the electrocatalytic reduction of CO to CO using covalently N-decorated carbon nanotubes as highly efficient and chemoselective metal-free electrocatalysts.
