Many do not realize the current and potential benefits of titanium dioxide (TiO2) and how it can meet some of our growing societal challenges.
Beyond its well-established use as the white pigment of choice in coatings, plastics and paper applications, TiO2 has been at the heart of the fight against air pollution for more than three decades. As a key element of environmental catalysts found in trucks and power plants all over the world, the ultrafine form of TiO2 has been used to reduce nitrous oxides (NOx) by millions of tons, and is continuing to do so as more and more countries are embracing more stringent regulations to control and reduce emissions.
In the recent years, latest generations of photocatalytic titanium dioxide, properly formulated, have demonstrated their effectiveness in the removal of atmospheric pollutants. These formulations can be applied on multiple construction and road materials.
However, the removal of pollution at source, or from the ambient, is not enough anymore. TiO2 can now be used to generate and store cleaner and renewable energies. The product is already used in some large-scale battery technologies, but numerous new applications are developed that incorporate TiO2 directly or in derivate materials. Regarding the production of energy, some of the latest generation of solar cells use nanotechnology TiO2 in ultra-thin layers.
Access to safe and pure drinking water constitutes another significant challenge for our modern society. Compared to the traditional water treatment techniques like flocculation and filtration, or chemical treatment, TiO2 can combine two ways to treat water. TiO2 is an absorbent that can remove contaminates, like arsenic, and its photocatalytic properties can destroy organics, including PCBs. This is two effects in one.
Environmental catalysis, photocatalysis, energy storage and water treatment are only a few of the applications that use TiO2 as a key element. Other large applications, such as electronics, structural ceramics, catalysis and cosmetics, are expanding and many others are emerging.
Next to its amazing technical properties, TiO2 also offers real strategic and safety benefits. Titanium is the ninth most common element at the surface of earth and naturally occurs as TiO2. The mineral can be mined in many parts of the world and is not subject to quotas or supply restriction. TiO2 is also a non-toxic and safe material, and its inertness has been reported many times in academic and independent studies. As a responsible industry, the Titanium Dioxide Manufacturing Association (TDMA) is investing in scientific programs to acquire further data on the product inertness.
The CristalACTiVTM team will continue to provide updates on the uses and benefits of TiO2 in several applications aiming to improve our lives and to meet global environmental challenges.
