Superior catalytic performance and CO tolerance of Ru@Pt/C-TiO2 electrocatalyst toward methanol oxidation reaction

Hofmann-like metal–organic-framework-derived PtxFe/C/N-GC composites as efficient electrocatalysts for methanol oxidation

“…It has been reported that the catalysts shows a rapid current decay during the chronoamperometry measurement process due to the formation of CO-like intermediate species adsorbed on the catalyst active sites. [53][54][55][56] It should be noted that Pt x Fe/C/N-GC-700 exhibited the highest retained current density during the electrochemical measurements, which suggests an excellent electrocatalytic stability during the MOR. Furthermore, some studies have reported that N-doped carbon support materials can enhance the durability and electrocatalytic activity by anchoring of the particles and accelerating charge transport during the catalytic process.…”

Promoted Alkaline Hydrogen Evolution Reaction Performance of Ru/C by Introducing TiO2 Nanoparticles

“…Finally, the above suspension was filtered and dried in vacuum oven at 60 °C overnight. Subsequently, Ru nanoparticles were dispersed on C−TiO 2 by using RuCl 3 as precursor and ethanol as reducing agent through a facile reflux method which referred to my previous work . More specifically, 4 mM 75 mL RuCl 3 ethanol solution was refluxed at 110 °C with rigorous stirring for 1 h in a three‐necked flask; Meantime, 100 mg C−TiO 2 was dispersed into 30 mL ethanol by sonication for 20 min and then the obtained suspension was transferred into the above three‐necked flask.…”

“…Subsequently, Ru nanoparticles were dispersed on CÀ TiO 2 by using RuCl 3 as precursor and ethanol as reducing agent through a facile reflux method which referred to my previous work. [10] More specifically, 4 mM 75 mL RuCl 3 ethanol solution was refluxed at 110°C with rigorous stirring for 1 h in a three-necked flask; Meantime, 100 mg CÀ TiO 2 was dispersed into 30 mL ethanol by sonication for 20 min and then the obtained suspension was transferred into the above three-necked flask. As reaction flask was stabilized at 110°C, 9 mL 0.1 M NaOH was added into the solution and reacted for 2 h. After that, the reaction was finished and cooled down naturally to room temperature.…”

Microemulsion Derived Titania Nanospheres: An Improved Pt Supported Catalyst for Glycerol Aqueous Phase Reforming

“…This makes TiO 2 a suitable material for different applications. For instance, it is widely used as electrochemical catalytic support for electro-oxidization in fuel cells [ 48 , 49 , 50 ]. In addition, it has been widely applied as a photocatalyst in wastewater treatment [ 51 , 52 ], pollutants abatement [ 53 , 54 ], solar hydrogen production [ 55 , 56 , 57 , 58 ], and oxidation reactions [ 59 , 60 ].…”
