Enhanced Thermal- and Photostability of Trace Pyrazine-Incorporated Hydrogen Boride Nanosheets. [PDF]

Small
Pyrazine‐incorporated hydrogen boride (Pyrazine‐HB) nanosheets exhibit significantly enhanced thermal and photostability while retaining a high hydrogen content. Trace pyrazine incorporation increases the hydrogen release temperature by ≈200 K and suppresses UV‐triggered desorption.
