Zinc oxide - Wikipedia

Zinc oxide is an inorganic compound with the formula Zn O.ZnO is a white powder that is insoluble in water. It is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes.

Room temperature ultrafast synthesis of zinc oxide ...

Dec 01, 2020  The preparation of ZnO NMs was performed in gas–solid phase by introducing ZnH 2 gas (generated on-line by reducing Zn 2+ with KBH 4) into carbon cloth (CC) in a sealed headspace bottle. ZnH 2 was unstable, can easily decompose and react with O 2 in the headspace bottle to form ZnO NMs on CC. The whole preparation process was completed in ...

Jul 18, 2003  Zinc nitrate precipitated with NaOH solution at room temperature under double-jet conditions produced micrometric zinc oxide particles with ellipsoid or starlike morphology separated by only a slight variation of pH (9.5 and 10.5, respectively). The formation kinetics of starlike particles was followed by SEM observations, suggesting that they result from a solid-state transformation of the ...

Room-temperature hydrogen sulfide removal with zinc oxide ...

Mar 01, 2019  Melt infiltration was used to prepare supported zinc oxide (ZnO) adsorbents for hydrogen sulfide (H 2 S) removal at room temperature, with three molecular sieves (MCM-41, SBA-15, and MCM-48) as carriers. The physical/chemical properties and the performance of these adsorbents were compared with those prepared by impregnation.
