Abstract:
In this study, two novel crystal materials pcp1 and pcp1-L have been synthesized successfully. The different conformations of the two crystals are mainly attributed to the introduction of the Schiff-base ligand L (L=(E)-4-methyl-N-((6-methoxypyridin-2-yl)methylene)aniline). Subsequently, pcp1 and pcp1-L composites have been firstly produced by a vacuum filtration method on various substrates (i.e., melamine foam, plastic mesh, carbon fiber cloth and glass cloth). The obtained robust composites show excellent performance in removing PMs owing to high ζ potential, microporous structure, large conjugation system and electron cloud-exposed metal center (DFT calculations) of pcp1 and pcp1-L. Particularly, pcp1-L@glass cloth with low pressure drop exhibits high thermal stability and high long-term reproducibility. Additionally, the high removal efficiency of pcp1-L@glass cloth towards particulate matters could also be maintained, even achieving >99.9 % in the car exhaust gas field test.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
