Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation

open access: yesAdvanced Science, EarlyView.
Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

In Situ Generation of Gel Foam via Heat‐Accelerated Calcium Ion Release From Nano‐CaCO3 for Lithium‐Ion Battery Fire Suppression and Prevention

open access: yesAdvanced Science, EarlyView.
We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...
