Abstract Hydrogen peroxide (H 2 O ) electrosynthesis via the 2e − oxygen reduction reaction (ORR) is considered as a cost‐effective and safe alternative to energy‐intensive anthraquinone process. However, in more practical environments, namely, use of neutral media air‐fed cathode slow ORR kinetics insufficient supply pose significant challenges efficient H production at high current densities. In this work, mesoporous B‐doped carbons with novel curved B 4 C active sites, synthesized carbon dioxide (CO using pore‐former agent, simultaneously achieve excellent activity improved mass transfer properties are introduced. Through combination experimental analysis theoretical calculations, it confirmed that configuration, formed by mesopores carbon, demonstrates superior selectivity for due its weaker interaction *OOH intermediates compared planar media. Moreover, facilitate suppress hydrogen evolution reaction, achieving Faradaic efficiency 86.2% 150 mA cm −2 under air‐supplied conditions, along an impressive utilization 93.6%. This approach will provide route catalyst design environment.

Abstract The sensitive detection of low‐concentration gases has significant implications for environmental monitoring, clinical diagnosis, and other fields scientific inquiry. Electrochemiluminescence (ECL) is a widely accepted analytical technique known its high sensitivity, precision, minimal background interference. Nevertheless, it rarely been documented in the context gas‐oriented sensing. This study presents an innovative paradigm gas sensing, which integrates oxygen reduction reactions (ORR) diffusion electrode (GDE) into flow micro‐reaction device. integration aims to optimize mass transfer, ensure adequate electrochemical contact, facilitate efficient electron ultimately enhance ECL emission. viability this effective situ sensing strategy under mild conditions without pre‐treatments substantiated by experimental model calculation evidence. homemade device enables quantification formaldehyde with limit determination (LOD) as low 12.7 ppb paves way universal gaseous
