Efficient and Durable Photochemical CO2 Reduction by TiO2‐Immobilized Metal Porphyrin Catalysts

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
A dye‐sensitized TiO2 scaffold bearing IrP and 3d‐metalloporphyrin catalysts (M‐TCPP; M = Fe, Co, Ni, Cu) drives efficient CO2‐to‐CO conversion and H2 evolution. Robust TiO2 immobilization and rapid interfacial electron transfer within the ternary architecture underpin the markedly enhanced activities relative to the mixed homogeneous systems.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.
