methanal,

IUPAC name for formaldehydeformaldehyde
, HCHO, the simplest aldehyde. It melts at −92°C;, boils at −21°C;, and is soluble in water, alcohol, and ether; at STP, it is a flammable, poisonous, colorless gas with a suffocating odor.

The experimental results showed that a suitable amount of CoS could significantly enhance the photocatalytic activity of Ti[O.sub.2] for [H.sub.2] and methanal production.
The experimental results demonstrated that a dramatic enhancement of sensing characteristic of cubic [In.sub.2][O.sub.3] has been achieved in comparison with the single [In.sub.2][O.sub.3] materials, and the cause for the improvement of gas sensing property to methanal can be assigned to the deliberate surface ornament of cubic [In.sub.2][O.sub.3] substrate with petal-shaped NiO nanoparticles.
The dynamic sensing transients of sensors (pure [In.sub.2][O.sub.3], NiO/[In.sub.2][O.sub.3] by hydrothermal reaction for 3.0 h and NiO/[In.sub.2][O.sub.3] by hydrothermal reaction for 24.0 h) to 600 ppm methanal gas were measured at 260[degrees]C (in Figure 4).
The methanal formation was determined using Nash method at a wavelength of 412 nm.

Also, formaldehyde (methanal [HOCH]) values of the particleboards were determined by the perforator method but not published.
