Ammonia assisted regulation of nitrogen-type in carbonaceous support applied for oxygen reduction reaction

Doping Nitrogen in carbon is crucial to modulate its catalytic performance. However, the configuration of doped nitrogen is hard to regulate. In this work, an ammonia assisted in-situ pyrolysis method was proposed to regulate the type of N in N-doped porous carbon supported Co3O4 prepared based on the Schiff base reaction between glucose and urea. XPS and FT-IR spectra found that ammonia affects the percentage of C = N formed between glucose and...
