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

Advanced Science, EarlyView.We apply ex situ and in situ scanning transmission X‐ray microscopy to reveal the structural degradation of polymer electrolyte membrane fuel cell catalyst layers due to conditioning and thermal heating of the catalyst coated membrane. We observe a redistribution of the ionomer and carbon‐black in the catalyst layer, as well as nanoscale membrane ...

Advanced Science, EarlyView.An interfacial electric field engineering strategy is proposed to trigger the self‐limiting surface reconstruction of high‐entropy heterostructures. Driven by this built‐in field, the controlled sacrificial leaching of W evolves a robust active layer, enabling exceptional oxygen evolution performance and ultrastability at ampere‐level current densities

Advanced Science, EarlyView.The cathode of proton exchange membrane water electrolyzers remains a poorly understood region despite its importance for hydrogen purity and operational safety. Operando synchrotron X‐ray radiography directly visualizes liquid water behavior and uncovers a transition from continuous to pulsating transport, providing new insight into multiphase ...
