Histograms of particle size distribution

Typical HRTEM images of samples calcined at different temperature and then activated at 800°C are reported in Fig.3, along with the histograms of particle size distribution.

The catalyst l%Pd Au/C (2) was characterised by TEM, HRTEM and EDX spectroscopy. The observations on the morphology and the microstructures of both the phase and the composition highlight its single phase property. The overview of the catalyst (Fig. 1) shows that the nanoparticles are evenly distributed on the active carbon. The inserted histogram of particle size distribution indicates that most particles are smaller than 10 nm in size. The size distribution is described by a Gaussian function centered at 3.4 nm, with 2 % particles oversized (from 10 nm up to 30 nm).

Fig. 4.2.9 Histograms of the size distributions of the particles shown in Fig. 4.2.8. Original and final size distributions are shown by broken and solid lines, respectively. The diameter of an equivalent sphere having the same volume as a nonspherical particle was obtained with a Coulter counter. (From Ref. 9.)...

Figure 1 represents a particle size distribution histogram. Where a preponderance of smaller particles occurs, the curve is right skewed and where a preponderance of larger particles occurs, the curve is left skewed. The symmetrical histogram is rarely found in practical applications.

The shade of a product is another parameter which is influenced by the particle size (Sec. 1.6.1.2). This is easy to see by comparing the reflection curves of two Pigment Yellow 83 white reductions in an alkyd-melamine resin system. The electron photomicrographs in Fig. 65 and the particle size distribution histograms in Fig. 66 represent these samples. At equal pigment concentration, curve 1 of the two remission curves in Fig. 67 reflects the behavior of the pigment with the smaller...
