Low-loaded Ru on hollow SnO₂ for enhanced electrocatalytic hydrogen evolution

Abstract

In response to the challenges of intermediate poisoning and the high cost of noble metal catalysts in hydrogen evolution reaction (HER), we develop a Ru-doped SnO2 catalyst. Such Ru-SnO2 catalyst...

Regulation of the microenvironment of Pb2O3@Bi2O3-tube by structural reconstruction for boosting the electrochemical ozone production performance

“…31,32 Pb 2 O 3 @Bi 2 O 3 -tube exhibited a more richer oxygen vacancy structure of up to 45.30%, which was higher than Pb 2 O 3 (38.04%) and Bi 2 O 3 -tube (36.18%), providing additional catalytically active sites and accelerating the reaction kinetics of the electrocatalyst. 33,34 In addition, the vacancy structures of Pb 2 O 3 @Bi 2 O 3 -tube were analyzed by electron paramagnetic resonance (EPR), as indicated in Fig. S9 †.…”

Ultrathin core–shell Au@RuNi nanowires for superior electrocatalytic hydrogen evolution

“…12–14 Simultaneously, the high oxygen affinity and low energy barrier of Ru contribute to facilitating the dissociation of H 2 O, consequently enhancing the alkaline HER activity. 15,16…”

Nitrogen-Doped CoP-Co2P-Supported Ru with Interconnected Channels through a Microwave Quasi-Solid Approach for Hydrogen Evolution Reaction over a Wide pH Range

“…Then, it is necessary to enhance the catalytic activity of TMPs through further modification. At present, many approaches have been developed to optimize the reaction kinetics of catalysts, including ion doping, 12−14 interface engineering, 15 alloy engineering, 16,17 precious metal loads, 18 defect engineering, 19 and so on. 20−22 Ion-doping engineering is an efficient and simple avenue to improve the catalytic activity of TMPs.…”
