Selective CO-to-hydrocarbon conversion in formic acid–promoted borohydride hydrolysis for PEMFC-grade hydrogen production

Inseok Lee, Chan Kim, Hyun Sung Lim, Felicia Alvita Theda et autres

Formic acid (FA)–mediated sodium borohydride (SBH) hydrolysis offers high system-level hydrogen storage density for on-board PEMFC applications, but often generates transient CO concentrations due to FA decomposition far exceeding the CO tolerance of PEMFC anodes. Existing CO removal strategies are limited in …

The Potential of Methyl Groups: Can Methyl Groups Unlock Reactivity Limitations of the Acceptorless Dehydrogenation of N-Heterocycles?

Jeong Jae Lee, Kwanyong Jeong, Su Bin Roh, Sunil Kwon et autres

High Resolution Image Download MS PowerPoint Slide We systematically investigated how the position of the methyl group in methylpiperidine/methylpyridine (MPI/MPY) pairs governs its acceptorless dehydrogenation reactivity through three perspectives─thermodynamics, kinetics, and adsorption. Among the MPI isomers, 2-MPI shows the highest conversion of …

High-pressure, grid-independent hydrogen generation via chemical hydride hydrolysis: Demonstration and deployment strategies

Chan Hyeok Kim, Jaewon Kirk, Felicia Alvita Theda, Eui‐Rim On et autres

High-pressure hydrogen refueling stations currently face challenges due to their reliance on mechanical compressors with high electricity consumption, grid dependency, durability issues and stringent installation requirements. This study introduces a non-mechanical, grid-independent hydrogen on-site production and compression system utilizing acid-mediated hydrolysis of …

Pushing the limits of sodium borohydride hydrolysis for on-board hydrogen generation systems

Jaewon Kirk, Yoondo Kim, Yu Jin Lee, Minkyu Kim et autres

Sodium borohydride (SBH) is a promising hydrogen (H2) carrier; however, its successful deployment has been limited to unmanned aerial vehicle applications. We reevaluated SBH hydrolysis for on-board vehicular applications from an entirely new perspective using solid-phase SBH hydrolysis with a CO2-derived acid …
