Shaping Carbon Nitrides for Advanced Macrostructures

Advanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Tuned Oxidation Potential of Continuous Defective Photocatalyst for Selective Biomass Conversion

Advanced Science, EarlyView.
This work develops a wavelength‐controlled photocatalytic strategy that utilizes defect‐state excitation to modulate oxidative capability for biomass selective conversion. By tuning the photooxidation potential to match substrate reactivity, the system suppresses overoxidation and enables the selective formation of value‐added products, providing a ...
