Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%
