For a friend who bought a new car must have heard "photocatalyst" The words, as many projects recommended 4S shop or beauty car bodies, new cars do photocatalyst can reduce vehicle pollution. I believe that many owners have also tried, but this illusory project is valid? Whether or experience the psychological effect, we reflect varied on whether photocatalyst really useful debate has not stopped, what can photocatalyst effectively reduce vehicle pollution, and today we will use the data to verify.

Test principle

In order to ensure an objective and true test has a certain universality, we selected the time is not more than one month's prospective new car purchase were two photocatalytic tests in the same environment as much as possible. And one of them in the professional beauty shop, then buy another photocatalyst carried DIY products, take a look at photocatalyst work carried out in different ways, it is effective in reducing air pollution.

What photocatalyst that?

Before the beginning of the text, let's talk photocatalyst, I believe that many friends have heard is not clear, this seemingly illusory photocatalyst what is the matter, relying on what principle work with.

Also called photocatalyst the photocatalyst, titanium dioxide is the main component, in the absorption of sunlight or ultraviolet light source in illumination, redox reaction to form strong oxidizing hydroxyl radicals and superoxide anion radicals, the harmful air species (including benzene, xylene, formaldehyde, ammonia and other volatile organic compounds) and decomposed by microorganisms into harmless carbon dioxide and water, so as to achieve air purification and sterilization purposes.

If some friends think this description is not straightforward, so simple, we always open the window ventilation can accelerate the evaporation of harmful gases, the equivalent of photocatalyst further accelerated this volatile effect.

Test background

Test car: Ford stroke/Ford Focus, the two vehicles were buying time in early May 2013, and have not done any decoration, while not as obvious photocatalyst car smell.

Data collection: two acquisitions are performed before and after the vehicle pollutants photocatalyst data collection and testing work performed by a professional third party testing laboratories, test data before each time the two vehicles are parked 10 hours.

Environmental samples: basement of a building, the temperature is relatively constant.

Data acquisition time: 3 days after the end of each car photocatalyst

The first sample

10 hours in advance we will test two vehicle into the basement of a building, and close the window, stop using it. The storage temperature is relatively constant, the first sample starts, Staff professional equipment, sampling time 20 minutes, test data is returned in 3 days.

The first set of raw data obtained later, we can begin construction next photocatalyst, and we were on the two vehicles will be tested photocatalyst, and then continue testing data.
