An Intelligent Deep Learning Model for Adsorption Prediction

Table 4

Pearson’s coefficient matrix for all features included in the research. Insignificant correlation was found between the inputs, only textural features (surface area, pore volume, and macropore volume). The features with units are depicted as follows: surface area: (m²/g), pore volume: (cm³/g), macropore volume: (cm³/g), H: hydrogen, N: nitrogen, O₂: oxygen, and CO₂ adsorption (mmol/g).

	Surface area	Pore volume	Macropore volume	O2	N	H	CO2
