Chemically driven micro-and nanomotors (MNMs) have emerged as a potential alternate to conventional techniques for the removal of toxic inorganic and organic pollutants. Their self-propulsion in the presence of a chemical substance (fuel) enhances mass transfer without requiring external energy input, thereby increasing the rate of diffusion-limited processes. Moreover, the motility of MNMs in the presence of different chemicals can be used as a gauge to estimate relative levels of contamination. A chemical modification of the outer surface of MNMs with a self-assembled monolayer of a hydrophobic compound allows capture, transport and removal of oil droplets from contaminated water. Several different materials have been investigated to prepare catalytic MNMs, most of which are metallic, such as platinum, silver, magnesium, iridium etc. Examples of metal oxides for the preparation of MNMs are rather rare. were the first to observe motion of commercially obtained MnO2 particles in the presence of H2O2, but the motion was rather slow and required a high concentration of the fuel. Later, few other groups reported MnO2 based micromotors that could propel in relatively less concentrated H2O2 solutions. Ye et al. introduced FeOx-MnO2 and Ag-MnO2 based microtubular motors with ultrafast speeds and propulsion in very dilute H2O2 solutions. Wang et al. studied MnO2 micromotors for drug delivery, whereas Villa et al. used Fe2O3-decorated MnO2 based microtubular motors for the removal of heavy metals and photocatalytic degradation of organic pollutants. He et al. investigated MnO2 for the removal of organic dye from contaminated water. Our group has extensively studied the synthesis of MnO2 based micromotors of various geometries and evaluated the effect of polymorphic forms on motion. We used MnO2 to protect Au/Pt based tubular micromotors from thiol toxicity during the surface functionalization with an alkanethiol, and demonstrated a proof-of-concept application of MnO2 particles to decolorize polluted water form toxic organic dyes. Here, we expand our previous work on water remediation by performing a detailed study of the use of MnO2 particles to remove rhodamine 6G (R6G) from polluted water. We analyze dye removal efficiency of the MnO2 micromotors in different dye concentrations, in different H2O2 concentrations and using different quantities of MnO2 particles. This study is vital for the assessment of a true potential of MnO2 based micromotors for environmental remediation applications.
