KCC-1 can enhance mass transport by its unique and hierarchical pore structures. A study on the diatomic molecule nanofluidic behavior can be a reference to understanding the transport kinetics in KCC-1. In this study, we report a comparison with MCM-41 and Silica Gel 60. At the earliest time, the adsorption process on KCC-1 provides effective mass transport kinetics among others. Thus, KCC-1 offers better performance for applications as host or support in the catalysis process.

In this system, PANI behaves as an organic p-type conducting polymer while N719 acts as an n-type semiconductor. The fabrication was carried out using different methods to deposit each component: solution casting for PANI, spray coating for N719, and screen-printing for silver paste. The PANI film was doped by soaking it in HCl solutions of different concentrations to form emeraldine salt, i.e., a conductive type of PANI. Electrical characterizations of PANI and the diode were performed using conductivity and current density-voltage (J-V) measurements. The maximum conductivity of PANI was obtained at 3.18 9 10 À2 S/cm using an HCl concentration of 1 M. The fabricated diode exhibited a low Schottky barrier (U B = 0.48 eV) and rectifying behavior (c $ 9) with moderate ideality factor (g $ 8). Acid doping of PANI caused better diode performance and an increase in current density by four orders of magnitude.
