Transport Behavior of Engineered Nanosized Photocatalytic Materials in Water

Table 5

The factors affect the aggregation behavior of PCNPs as NOM exists.

	Factors	Cause
Reduce; aggregation	High NOM molecular weight	Sterical repulsion
	High NOM aromatic carbon content	𝜋-𝜋 interaction
Induce; aggregation	High cation concentration	Charge neutralization
	Light irradiation	NOM degradation
