Facile, Morphology-Controlled and Mass Production of 0D-Ag/2D-g-C3N4/3D-TiO2 Nano-composite Materials: Effect of Silver Morphology and Loading on the Electrochemical Performance

The 0D-Ag/2D-g-C3N4/3D-TiO2 nano-composite materials were fabricated by simple and mass production method. It involves the combination of incipient wetness impregnation and thermal spreading techniques. By changing the order of impregnation and thermal spreading, silver nanoparticles with “on-top” and “embedded” morphologies could be selectively controlled. The thermal spreading followed by impregnation (TS-IM) leads to the “on-top” structure [Ag/g-C3N4/TiO2] while, the reverse order (IM-TS) produces the embedded silver nanoparticles [g-C3N4/Ag/TiO2].
