Highly efficient electrochemical generation of H2O2 on N/O co-modified defective carbon

Oxygenated P/N co-doped carbon for efficient 2e−oxygen reduction to H2O2

“…The above results conclusively signify that O-P/N-C900 can produce H 2 O 2 at high current densities at a large scale. In addition, very high faradaic efficiencies (FEs) of 85% to 95% were achieved in a potential range of 0.1 to 0.3 V, which is higher than most reported values, 40,54,[58][59][60][61][62][63][64][65][66] as compared in Fig. 4D.…”

Future perspectives for the advancement of electrochemical hydrogen peroxide production

“…Acronyms used in material descriptions are taken from the original works. Data taken from references [15,25,34,[38][39][40][41] Figure 2 highlights that the scope of possible materials is incredibly broad and outside the scope of this discussion. A number of excellent reviews are available for more detailed insights specifically into materials development.…”

Regulable pyrrolic-N-doped carbon materials as an efficient electrocatalyst for selective O2 reduction to H2O2

“…32 Nitrogendoped porous carbon electrocatalysts have a high specific surface area, which is helpful for exposing more active sites, providing faster channels for reactant diffusion and electrocatalyzing the 2e À ORR more effectively. 26,[28][29][30][31] However, regardless of whether the nitrogen-doped porous carbon materials are prepared using hard templates, 33,34 soft templates 35 or template-free methods, the catalyst synthesis processes are complicated, 29,36 which will increase the cost of practical applications. Moreover, before using carbon-based materials like graphene, carbon black, carbon nanotubes, and so on, it is usually necessary to pretreat the carbon materials with dangerous strong acids or bases, such as the well-known Hummers' oxidation method.…”
