The Co_(3)O_(4)nanoparticles,dominated by a catalytically active(110)lattice plane,were synthesized as a low-temperature NO_(x) adsorbent to control the cold start emissions from *** nanoparticles boast a substantial quantity of active chemisorbed oxygen and lattice oxygen,which exhibited a NO_(x) uptake capacity commensurate with Pd/SSZ-13 at 100℃.The primary NO_(x) release temperature falls within a temperature range of 200-350℃,making it perfectly suitable for diesel *** characterization results demonstrate that chemisorbed oxygen facilitate nitro/nitrites intermediates formation,contributing to the NO_(x) storage at 100℃,while the nitrites begin to decompose within the 150-200℃***,lattice oxygen likely becomes involved in the activation of nitrites into more stable nitrate within this particular temperature *** concurrent processes of nitrites decomposition and its conversion to nitrates results in a minimal NO_(x) release between the temperatures of 150-200℃.The nitrate formed via lattice oxygen mainly induces the NO_(x) to be released as NO_(2) within a temperature range of 200-350℃,which is advantageous in enhancing the NO_(x) activity of downstream NH_(3)-SCR catalysts,by boosting the fast SCR reaction *** to its low cost,considerable NO_(x) absorption capacity,and optimal release temperature,Co_(3)O_(4)demonstrates potential as an effective material for passive NO_(x) adsorber applications.

Hydrogen is a promising renewable fuel with broad applications, but its flammability and tendency to leak through metals create safety challenges, necessitating reliable, standalone, and affordable sensing systems. Current hydrogen sensors are often costly, suffer from cross-sensitivity to gases, and are typically not standalone. Our sensing approach is based on the hydrogenation of the fluorophore 1,4-bisphenylethnylbenzene (PEB). This approach encompasses two levels of visual sensing: rapid detection via surface color change and quantitative "litmus paper"-like analysis and cross-section observation, which provides a hydrogen exposure history and other parameters such as hydrogen partial pressure and exposure time. The sensor detection limit is 1 mbar ( © 2025 Hydrogen Energy Publications LLC
