TS EN 16981

TS EN 16981 is a glossary standard that gathers the terms and definitions used in photocatalysis. Photocatalysis relies on light-activated semiconductor materials that accelerate chemical transformations in their surroundings, which places the subject at the intersection of surface science, coating technology, environmental treatment and functional materials. This standard is intended to keep terminology consistent and aligned with the scientific literature.

Why photocatalysis needs a dedicated glossary

Photocatalysis uses a cluster of closely related but technically distinct concepts: light source, wavelength, catalyst activation, surface reaction, adsorption and degradation. A glossary standard helps ensure that these terms are used with the same meaning across standards and technical documents. In general, such a document does not set performance thresholds or test procedures; it establishes language consistency and reduces ambiguity between related standards.

What this standard covers

The standard lists a consistent set of definitions for use in photocatalysis standards and ties them to the scientific literature. In practical technical context, photocatalysis is commonly discussed in relation to pollutant breakdown, self-cleaning surfaces, and air or water treatment. This product listing is therefore about terminology rather than a test method or a performance specification.

Its main value is that the same term can be understood in the same way in research papers, technical specifications and related standards. That makes core concepts such as photocatalytic activity, reaction mechanism, light activation and surface interaction easier to distinguish and use consistently.
