Layer‐Wise Titania Growth Within Dimeric Organic Functional Group Viologen Periodic Mesoporous Organosilica as Efficient Photocatalyst for Oxidative Formic Acid Decomposition

bridge dimeric organic functional group viologen PMOs synthesized via layer by layer growth on titania (TiO2) has been unprecedently prepared as stable periodic mesoporous organosilica using surfactant under mild acidic conditions. The layer by layer TiO2 incorporation within the prepared organic functional group viologen‐PMO could successfully develop a new type of hybrid photo‐oxidation system for the mineralization of formic acid under sunlight irradiation conditions. It's always the sun: A bridge dimeric ionic liquid organic functional group viologen (Dim‐IL) PMOs synthesized via layer by layer growth on titania (TiO2) has been unprecedently prepared as stable periodic mesoporous organosilica using surfactant under mild acidic conditions. The layer by layer TiO2 incorporation within the prepared bipyridinium organic functional group viologen‐PMO could successfully develop a new type of hybrid photo‐oxidation system for the selective oxidation mineralization of formic acid under sunlight irradiation conditions.
