In Situ Preparation of Polyamine-Derived Ru Cluster@N-Doped Porous Carbon Nanoplates for Hydrogen Evolution over Wide pH Ranges

“…The ECSA value can be calculated using the double-layer capacitance ( C dl ) and Cu under the potential deposition method (Cu UPD), , where the C dl is determined to be linearly proportional to the number of active sites (Figures e and S13). After calculation from the equation of ECSA = C dl / C s (where the C s value is the specific capacitance of the electrode under 0.5 M H 2 SO 4 solution), the ECSA of Ru cluster@NCs is 30.70 m 2 g –1 , which was larger than that of commercial Pt/C (29.67 m 2 g –1 ), Ru(10%)@NCs (7.77 m 2 g –1 ), and Ru(1.5%)@NCs (6.76 m 2 g –1 ). The values agree with those measured by Cu UPD (Figure S14).…”

Surface/Interface Engineering of Hierarchical MoO2/MoNi4@Ru/RuO2 Heterogeneous Nanosheet Arrays for Alkaline Water Electrolysis with Fast Kinetics

“…The C dl values were determined by the gradient of the graph of capacitive current density against scan rates. [ 55 ]…”

Rapid, self-sacrificing template synthesis of two dimensional high-entropy oxides toward high-performance oxygen evolution

“…In order to overcome the thermodynamic immiscibility of various metal elements with different crystal structures and electronegativity in HEOs, high-temperature heat treatment is a common method for the preparation of HEOs. 30,31 Yet, most of the samples synthesised in this way are micron-sized particles with small specific surface area, which is not conducive to the generation of abundant catalytically active sites. Traditional heating methods have problems such as slow heating speed, low productivity, and the inability to directly control the reaction temperature, heating speed, stirring speed and reaction time, resulting in poor repeatability and uniformity, and for the emerging microwave heating methods the internal temperature is still a challenge.…”
