Measuring Metal. Second we provide some general guidelines for experimentally measuring the electrochemically active surface area (ECSA) Third we review the methods for the surface area measurement of metal oxide electrocatalysts The detailed procedure for each method is explicitly described to provide a stepbystep manual that guides researchers to.
If you’re using a retractable tape measure (the kind that comes in a small metal or plastic box that automatically sucks the tape back up when you’re done with it) note that the end of the tape will almost always have a small metal notch at the zero mark This is useful for holding the tape in the right place as you measure so you may want to start by catching it on.
