How to select a better electrocatalyst, Is it from their Electrocatalytic surface area (ECSA) or ox./red. current density during various applications?

Taking the example of Au/Pd metal, the ECSA is calculated from the Au/Pd-reduction curve carried out in 0.1M HCLO4/H2SO4 as per many reports in the literature (ref. below). When the ECSA is...

How to carry out the XRD of MOF deposited on GCE?

Could anyone tell the procedure to carry out XRD of thin films of MOF deposited on GCE? Since for carrying out XRD, we require a minimum amount of 10-20mg of powder, and we get so less (0.5 mg) of...

From the XRD of AuNPs, should we consider only (111) plane for calulating mean size of Nps?

I obtained the XRD of the AuNPs, which has fingerprint diffraction peaks. Now to calculate the mean size by scherrer's equation, shall I consider only (111) plane or do I need to take the average...
