Catalytic Reactions In article number 2207666, Xiaoguang Duan, Shaobin Wang, and co-workers report on the application of well-designated multifunctional FeOx@MnO2@SiO2 micromotors as mobile microreactors for catalytic water purification. H2O2 is fuel to generate oxygen bubble propelling peroxymonosulfate green oxidant free radical species realize degradation emerging micropollutants in water. T...

The lipase from Candida Rugosa was immobilized to a poly(methacrylic acid) polymer brush layer, grown on the inner wall of silicon-glass microreactors. The hydrolysis of 4-nitrophenyl acetate was used as a model reaction to study the activity of this biocatalytic system. The amount of bound lipase could be tuned by changing the polymerization time of the brush formation. The Michaelis-Menten co...
