Which risk increases when titanium dioxide nanoparticles incompletely disperse during a catalyst synthesis?

A)Increased heterogeneous catalyst particle agglomeration

B)Decreased surface area mediated photodegradation rate✓

C)Elevated unwanted side-product formation rate

D)Compromised catalyst bed pressure drop

💡 Explanation

Reduced dispersion lowers the catalyst's active surface area because Ostwald ripening decreases the available reactive sites at a given mass loading. Therefore, potential reactions are limited causing a decreased photodegradation rate, rather than alternative reactions, because fewer molecules interact overall.
