The above-mentioned differences in the texture of the materials as a result of the differences in the chemical processes taking place during their formation are illustrated in Fig. 8. While the texture of Zn(OH)2 consists of loosely attached, small irregular particles and crystalline rhombic bipyramid particles of ε-Zn(OH)2[11], the addition of AuNPs results in the formation of two different crystal shapes of ZnO: cubic and rod-like crystals (Fig. 8B and C). The texture of ZnGO (Fig. 8D), however, resembles those previously reported [11] and [12]. As indicated in the literature, the carboxylic groups at the edges of GO layers are likely involved in the formation of “seeds” for the creation of a web-like network with the Zn(OH)2 phase connected to GO particles [11], [12] and [23]. AuZnGO composite prepared after the addition of AuNPs is the highly heterogeneous and amorphous material (Fig. 8E and F).
