Abstract
A method of photocatalytic degradation utilizes a particulate crystalline nanocomposite with a radiation having a wavelength of 100 to 800 nm. The particulate crystalline nanocomposite includes a tetragonal calcium molybdate (CaMoO4) crystalline phase, a calcium silicate (CaSiO3) crystalline phase, and a graphitic carbon nitride (C3N4) crystalline phase, where at least a fraction of the graphitic-C3N4 is in the form of mesoporous nanosheets.
Claims18
A method of photocatalytic degradation, comprising:
- contacting a particulate crystalline nanocomposite with an aqueous medium comprising one or more contaminants to form a pre-irradiation mixture,
- wherein the particulate crystalline nanocomposite comprises a tetragonal CaMoO4 crystalline phase, a CaSiO3 crystalline phase, and a graphitic-C3N4 crystalline phase having at least a fraction of the graphitic-C3N4 in the form of mesoporous nanosheets;
- irradiating the pre-irradiation mixture with a radiation having a wavelength of from about 100 to about 800 nm;
- thereby
- degrading the one or more contaminants on the particulate crystalline nanocomposite,
- wherein at least a fraction of the CaMoO4 and at least a fraction of the CaSiO3 of the particulate crystalline nanocomposite are in the form of spherical particles.
