The method of projections onto convex sets (POCS) is used to calculate the adsorption-energy distribution function from the adsorption integral (using a modified Langmuir local isotherm) for energetically heterogeneous surfaces. The POCS method, originally developed in the 1960s, has been successful
The temperature-programmed adsorption equilibrium of CO at 4 kPa on Pd/SiO 2 and of CO 2 at 101.3 kPa on β₯-Ga 2 O 3 was studied by infrared spectroscopy between 298 and 723 K. The relative coverage (ΞΈ) evolution of each adsorbed species as a function of the adsorption temperature was measured by nor
