Recent Advances in Engineered Ru‐Based Electrocatalysts for the Hydrogen/Oxygen Conversion Reactions

“…The ORR is a protonelectron transfer process that reduces oxygen to water through direct fourelectron reactions or hydrogen peroxide (H 2 O 2 ) by twoelectron reactions. [145] ORR involves in cathode reactions in fuel cells, and direct four electron transfer is an ideal reaction pathway. The twoelectron pathway provides a green synthesis route for H 2 O 2 , ascribing to the considerable application value for wastewater treatment and disinfection.…”

Ultrafine SnPd Nanoalloys Promise High-Efficiency Electrocatalysis for Ethanol Oxidation and Oxygen Reduction

“…Palladium (Pd) is regarded as a potential catalyst for direct ethanol fuel cells (DEFCs) due to its excellent performance in anodic ethanol oxidation reaction (EOR) and cathodic oxygen reduction reaction (ORR) under alkaline conditions. − However, the binding strength of Pd active sites for the reaction intermediates (e.g., O and OH in oxygen reduction and CO in the alcohol oxidation process) is too strong to allow their rapid conversion and desorption. − The introduction of another metal or metal oxide could weaken the binding of intermediate species on the Pd sites so as to enhance their catalytic performance. Among the additive candidates, tin (Sn) can change the charge distribution of Pd atoms and adjust their electronic band structure through the electronic effect, optimizing the interaction between Pd and intermediate species. − Furthermore, several studies have confirmed that the bifunctional role of Sn also makes it an excellent auxiliary catalyst component.…”

Evaluation of a photoelectrochemical platform based on strontium titanate, sulfur doped carbon nitride and palladium nanoparticles for detection of SARS-CoV-2 spike glycoprotein S1

“…Palladium is highly exploited in electrocatalysis of a number of species ( Li et al, 2005 ; Tronto et al, 2006 ; Domínguez-Domínguez et al, 2008 ) and it is highly exploited as nanoparticles supported on several materials in order to obtain palladium-supported nanoparticles of high stability and high surface-to-volume ratio ( Choudary et al, 2002 ; Yang et al, 2008 ; Gniewek et al, 2008 ). In addition, palladium nanoparticles based materials has been exploited in catalytic and electrocatalytic reactions of manys species ( Trzeciak and Augustyniak, 2019 ; Xu et al, 2022 ). The proposed PEC immunosensor exploits ascorbic acid as donor molecule.…”
