Does the height of the plateau (from where the isotherm is getting started) at low p/p0 in BET indicates more porosity or micropore volume?

I did not get any micropore from t plot. So I am confused wheather my sample does not have micropore or it is having but not showing as my data has not been taken so low relative pressure. We are...

Why the microporous sample is having more surface area than mesoporous one?

Two micropore each having radius r will have a surface area of 2pi*r2h (if h is the depth of the pore).Instead of that one mesopore have a radius of 2r. Then its surface area will be pi(2r2)h =...

During water oxidation in presence of organics why there is shift towards negative potential in the current potential curve of oxygen evolution?

The shift is due to the faster water oxidation in presence of organics in RuO2, IrO2 or graphite electrode as the organics are adsorbing the OH radical and helps to move the water oxidation...
