“…However, many previous works have shown that electrocatalysts based on N-doped carbon accelerate the 4e À ORR pathway under alkaline conditions. [30,67] Many efforts have sought to establish a fundamental understanding of the nature of the active sites in nitrogen-doped carbon materials. Most propose that, in alkaline medium, both pyridinic-N and graphitic-N species are considered active sites that promote the 4e À ORR pathway, [68][69][70] while pyrrolic-N has a favorable effect on the 2e À ORR pathway.…”

The oxygen reduction reaction (ORR) plays a pivotal role in electrochemical energy conversion and chemical production. Two‐electron (2e−) charge transfer for oxygen reduction is considered a promising method for the on‐site production of hydrogen peroxide (H2O2), which requires electrocatalysts with high H2O2 selectivity and ORR activity. Noble metal alloys (e.g., Pt‐Hg and Pd‐Hg) have been prevalent materials of choice due to their desirable intrinsic activity, but their scarcity and high cost seriously hinder their widespread application in practice. Self‐doped heteroatomic carbon‐based electrocatalysts, derived from abundant and inexpensive biomass, have emerged as attractive candidates for on‐site H2O2 production. This review summarizes the fundamentals and recent advances in H2O2 production via 2e− ORR, including basic catalytic mechanisms, the influence of electrolyte pH and porous structure of catalysts, selectivity assessment methods, determination of the cumulative H2O2 concentration, development of biomass‐derived carbon‐based catalyst, and electrochemical device designs. Current challenges and proposed opportunities are also presented with an emphasis on large‐scale electrochemical H2O2 synthesis.

Electrochemical energy conversion is an important strategy for addressing climate change and building a carbon‐neutral society. The use of inexpensive biomass resources to develop high‐performance catalytic materials that reduce the energy barrier of electrochemical reactions and minimize energy consumption has become a research hotspot for energy materials. Previous reviews have often categorized biomass‐derived catalysts by the biomass feedstocks used, but this classification method has major limitations because the roles of the same biomass material in different catalysts can vary. In this review, a new classification approach for biomass‐derived catalytic materials by focusing on the role of bio‐based materials in the overall catalyst system is proposed. The review is divided into three main sections, categorizing bio‐based materials by 1) the active components, 2) the carbon support, and 3) the entire catalyst. Additionally, a comprehensive summary is provided of catalytic materials at different scales, including the nanoscale, molecular scale, and single‐atom scale. It is hoped that this review will guide and inspire the future development of biomass‐derived electrocatalysts.

Biomass-derived carbon is a microwave-absorbing material that has shown considerable potential for diverse applications due to advantages such as the wide range of sources and the natural multilevel structure. However, the primary issues related to pure carbon materials are their weak absorption intensity and narrow absorption band. In this study, two-dimensional N-doped carbon sheets were prepared by using corncob as the biomass precursor and melamine as the nitrogen source. After nitrogen doping, the samples attained high loss capability in the low-frequency region and enhanced impedance matching in the high-frequency region due to the combined effects of the structure, morphology, and composition on the electromagnetic parameters. Therefore, the absorption performance of the full frequency band was significantly enhanced, which was conducive to broadband absorption. The optimal sample attained a minimum RL of −57.27 dB at 14.64 GHz when the sample thickness was 2.6 mm. In addition, the effective bandwidth was up to 8.26 GHz (9.74−18.00 GHz) when the thickness was 2.9 mm. The strong absorption and broad effective bandwidth indicate that the N-doped carbon sheet can be used as a potential microwave absorber.
