“…This catalyst is also one of the most efficient N and/or S‐doped carbon‐based catalysts reported to date (see Table S6). This highlights the interest in using ZTC‐based catalysts as ORR catalysts, with respect to doped graphene‐based samples, which suffer from sheet stacking [46,47] . From RRDE experiments complementary information on the selectivity of the reduction process was obtained.…”

“…This highlights the interest in using ZTC-based catalysts as ORR catalysts, with respect to doped graphene-based samples, which suffer from sheet stacking. [46,47] From RRDE experiments complementary information on the selectivity of the reduction process was obtained. The percentage of peroxide species formed during ORR as well as the number of electrons exchanged per oxygen molecule were determined from measured disk and ring currents (Figure 11).…”

Bio‐sourced Zeolite‐Templated Carbons (ZTCs) were achieved through the use of glycerol as carbon source. A systematic study of the textural and chemical properties is presented on ZTCs achieved at synthesis temperatures between 300 °C and 800 °C. Textural properties are importantly impacted through increasing synthesis temperature. ZTCs featuring high textural quality were synthesized at temperatures as low as 400 °C. Oxygen content was further found to be importantly impacted by the synthesis temperature. This latter plays a crucial role when materials are functionalized with thiourea, as high oxygen content allows for maximizing the incorporation of N and S in the ZTC. Functionalized bio‐sourced ZTCs allowed for achieving unparalleled ORR activities and hydroxyl selectivities when compared to other functionalized carbon materials such as graphene‐based catalysts.

“…Fuel cells and metal-air batteries are clean, efficient and safe batteries that convert chemical energy directly into electric energy, and they have the advantages of a high energy density, safety and environmental protection compared with traditional energy sources [ 1 , 2 ]. Currently, Pt-based cathode catalysts are widely used as the main catalyst of precious metals; however, high costs and limited reserves become major obstacles to the commercialization of fuel cells [ 3 , 4 , 5 ].…”

As a key role in hindering the large-scale application of fuel cells, oxygen reduction reaction has always been a hot issue and nodus. Aiming to explore state-of-art electrocatalysts, this paper reviews the latest development of nonmetallic catalysts in oxygen reduction reactions, including single atoms doped with carbon materials such as N, B, P or S and multi-doped carbon materials. Afterward, the remaining challenges and research directions of carbon-based nonmetallic catalysts are prospected.
