Provided are methods of preparing cannabinoids and cannabinoid derivatives and compositions containing the cannabinoids and derivatives.

Proposed is a photocatalytic complex. The photocatalytic complex includes a photocatalyst, and an iodine compound layer formed on a surface of the photocatalyst to cover the same and containing an iodine compound. The present disclosure enables selective degradation of hydrophilic volatile organic compounds by the use of the photocatalyst coated with the iodine compound.
