Can Lanshe No.1 really decompose formaldehyde?

Lanshe 1 adsorbs formaldehyde, but it can't decompose it. I personally did the experiment, that is, I dropped a drop of ammonia in a beaker and poured it into Lanshe 1, which immediately absorbed the smell of ammonia, but I couldn't smell it. But after heating Lanshe 1 with a shower lamp, I smelled it again, and it smelled it again.
