Activation of commercial Pt/C catalyst toward glucose electro-oxidation by irreversible Bi adsorption

Enhanced Electrocatalysis via Boosted Separation of Hot Charge Carriers of Plasmonic Gold Nanoparticles Deposited on Reduced Graphene Oxide

“…[27,36] As shown in Figure 2c, the anodic peaks at potentials > 0.8 V are due to formation of Au oxides (AuOx), and high reduction peaks at 0.93 V can be ascribed to the reduction of AuOx. [28][29][30] To quantify the gold loading on different electrodes, the inductively coupled plasma atomic emission spectrometry (ICP-AES) was used. The details including the charge quantity, real surface area of electrodes, peak current, and current density (J = I/(Real surface area)) of different electrodes with light on and off refer to Table S1 and Figure 2d.…”

“…The results highlight that the high hot electrons transfer efficiency of the AuNPs/rGO originates not only from the plasmonic effects but also from the presence of the rGO, which has been reported to exhibit excellent charge transport properties. [28][29][30] To quantify the gold loading on different electrodes, the inductively coupled plasma atomic emission spectrometry (ICP-AES) was used. The ICP-AES result indicates gold loading of 1.31 mg/L on synthesized AuNPs/rGO hybrid.…”

“…[28] In this work, AuNPs/reduced graphene oxide (AuNPs/ rGO) hybrid was in-situ synthesized and used as the catalyst for electrochemical oxidation of glucose (Scheme 1). The electrocatalysis of glucose has been widely studied for the reason of being as a detectable species for biosensors or as an energy source.…”

Electricity generation, salinity, COD removal and anodic biofilm microbial community vary with different anode CODs in a microbial desalination cell for high-salinity mustard tuber wastewater treatment

“…Moreover, the Pt/C catalyst without modification is less tolerant to poisoning, which would influence the catalytic reaction at the MDC cathode. 15 The cathode of the dual-chamber MFCs was the same as that in the MDCs, and the anolyte of the dual-chamber MFC was the desalinated MTWW from MDC. All the other reagents used in the experiment were of analytical grade.…”
