Water purification by nanomotors
Mg-nanomotors for removing Nitrite from
A
B
water
Aim: Use of Mg-nanomotor for rapid and effective
remeadiation
of
nitrite
from
drinking
water/groundwater.
Motivation: Nitrite is a toxic inorganic
contaminant that is hazardous to the health of
humans.
Approach: Mg nanoparticle is used to reduce the
nitrite into ammonia (60-95%) and nitrogen.

purification
by
electrochemistry
Electrocatalytic materials decorated with nanomaterials for removing
pollutants from water
Aim: Large disk electrodes of Ti/TiO2-nanotubes/PbO2 (65 cm2 of geometrical
area) are successfully synthesized by anodization and electrodeposition
procedures. Characterization of anodes was performed by SEM, EDS, AFM and
electrochemical measurements, aiming towards environmental applications.
PbO2, an electrocatalytic material, promotes the production of strong oxidizing
species (hydroxyl radicals) that can be used for decontamination of water.
