Facile synthesis of porous hybrid materials based on Calix-3 dye and TiO₂ for high photocatalytic water splitting performance with excellent stability

A highly robust hybrid material Calix-3-TiO2 based on calixarene dye and TiO2 is prepared by a facile sol–gel method for the first time. When Pt nanoparticles are introduced onto the hybrid, the catalysts display efficient and persistent photocatalytic water splitting activities.
