Abstract

Villous zinc oxalate (ZnC₂O₄) was successfully prepared from reduced graphene oxide (RGO) and zinc oxide using a two-precursor sol-gel method, and scanned using a matrix-dotted microbeam laser. Application of the laser caused the synthesized ZnC₂O₄ to melt and resolidify, forming uniformly spread nanovillous protrusions. The characteristics of the microstructures were examined using X-ray diffraction, energy dispersive X-ray analysis, field emission scanning electron microscopy, and Raman spectroscopy. Various ratios of RGO:ZnO were demonstrated to produce villous ZnC₂O₄; moreover, the structures of ï¡-ZnC₂O₄ and ï¢-ZnC₂O₄ were found to coexist in the sol-gel powders. ï¢-ZnC₂O₄ produces a villous shape because of a minute characteristic that favors the formation of such structures. The carbon from RGO is attracted through impurity sites, resulting in oversaturation with C/Zn at approximately the same ratio as that of RGO and ZnO because of the counter-ion effect between the cation and anion bonds.
