摘要

Particulate materials possessing dual functionalities have received tremendous investigations in many fields,owing to their superiority over mono-functional counterparts and their potential for process inte-gration and intensification.This review focuses on bi-functional catalytic particles which also serve as sorbents/adsorbents or heat suppliers in the scheme of various thermo-chemical processes,enabling inherent separation or energy conservation within single-step operation.Bi-functional particles applied for integration of reaction and separation including sorption-enhanced hydrogen production and inte-grated capture and catalytic conversion processes are reviewed in detail,providing insights into material design and key performance indicators.On the other hand,bi-functional particles applied for integration of reaction and non-thermal radiation heating,including electrothermal and photothermal assisted het-erogeneously catalyzed reactions,are also reviewed,with emphasis on the material property and energy efficiency improvement.These bi-functional particles show broad adaptability and feasibility in various reactions operated in integrated and intensified schemes,affording huge potentials for further improving productivity and efficiency in thermo-chemical processes.
