A method is disclosed in which a gas of hydrogen and nitrogen, or hydrogen and ammonia, or hydrogen, nitrogen, and ammonia, is introduced to a fluidized bed. The gas flows through the fluidized bed, and titanium dioxide particles are introduced to the fluidized bed to form a fluid mixture of the particles and gas in the fluidized bed. The particles are reacted with the gas in the fluid mixture to form particles including titanium dioxide and nitrogen. The particles can be disposed along an air flow path in operative communication with a light source for air treatment.
