Au 1 Pd 5 |

nm |
TEM |
TEM was performed to investigate the size distribution of monometallic and bimetallic NCs. As shown in Fig. 2a and b, NADH-reduced Pd NCs with 24 h-incubation exhibit the mean size of 1.1 nm, while Au NPs show the average diameter of 8.1 nm. Remarkably, both Au1Pd5 and Au1Pd1 exist as highly dispersed NCs, showing the average size of 1.4 and 1.6 nm respectively (Fig. 2c and d). The mean size increases in the order of Pd < Au1Pd5 < Au1Pd1 < Au, which is consistent with the relative content of Au species. Hence, it is reasonable that NADH facilitates the rapid formation of ultrasmall NCs within a suitable range of [Na2PdCl4]/[HAuCl4]. Further, the atomic ratio in bimetallic NCs was determined by ICP-OES. The molar ratio of [Au]/[Pd] is 1.3 for Au1Pd1 and 0.25 for Au1Pd5, which is close to the corresponding theoretical ratio of two precursors in synthesis process. |

The SEM images in Fig. 4 show the morphological and structural differences between PCN and CCN. PCN exhibited a fluffy-like structure with a small and irregular dense-texture as compared to CCN texture. These fluffy nanosheets were connected in such a way that they have left a small hollow space between them. In comparison, CCN exhibited a uniform surface texture, and g-C3N4 crystalline sheets were looked like large-sized aggregates. |

A summary of the comparison of the specific surface area (SBET), total pore volume, and pore width of PCN and CCN are listed in Table 2. PCN exhibited greater SBET (89.9 m2/g) than that of CCN (11.8 m2/g). This enlarged surface area can be attributed to porous, thin, and curled nanosheets in fluffy PCN as compared to crystallized, planar, and large layered nanosheets of CCN. |

The morphology of the His-AuNCs was studied via their TEM images taken.

The TEM images were also utilized to estimate the average diameters of the enlarged AuNPs seeds in the presence of glucose (Fig. 1B). The average diameters of His-AuNPs seeds were 10 ± 2 nm, while the diameter of enlarged AuNPs depend on the concentration of glucose and self-catalyzed activity of AuNPs. The TEM images reveal that the AuNPs in the presence of 50 μM glucose can be enlarged to an average size of 17 nm (Fig. 1C), while the diameter of enlarged AuNPs in the presence of higher glucose concentrations of 100 μM further increased to about 25 nm (Fig. 1D). |
