Titania NPs syntheses in continuous flow.

Oxide	Reactants	Methodology	Year	T	Shape	Size[a] (nm)	Size distribution (σd/d)	Ref.
TiO2	TTIP+H2O	ceramic microreactor chip	2002	RT	–	<10	–	[55]
TiO2	TTIP+H2O	axle dual pipe device (3D‐flow injection)	2004	RT	spherical	40–150[b]	–	[11]
TiO2	TTIP+H2O	droplet‐based reactor	2018	RT	spherical	8–10	–	[56]

[a] Calculated by TEM/SEM analysis. [b] Particles size depended on the inner channel width, fairly monodispersed NPs were obtained in single runs.
