The lack of highly efficient catalysts severely hinders large‐scale application of electrochemical hydrogen evolution reaction (HER) for hydrogen production from water. Herein, synergistic cascade hydrogen evolution boosting by combining the strategies of carbon layer confinement and surface oxophilicity modification is realized. The carbon layers confined ultrafine RuCr nanoparticles (RuCr@C) exhibit outstanding HER activity (j10 = 19 mV, turnover frequency = 4.25 H2 s‐1), surpassing the benchmark Pt/C and most of the reported HER catalysts. Combined experimental verifications and theoretical simulations reveal that surface adsorption modification and electronic structure regulation synergistically boosts the HER kinetics over the RuCr@C catalyst. The Volmer step is accelerated by stabilizing the final state of water dissociation (*H and *OH) through Cr doping, and the Heyrovsky step is promoted via carbon layers confinement. As such, this work highlights a synergistic cascade strategy to boost HER kinetics which is of fundamental importance to accelerate future advances in electrocatalysis.
Effective valorisation of biomass into value-added chemicals represents a promising strategy to reduce the reliance on fossil fuel energy, and 5-hydroxymethylfurfural (HMF) has been identified as a critical and versatile...
The alkaline hydrogen evolution reaction (HER) on Pt-based catalysts is largely retarded by insufficient supply of dissociated hydrogen (*H) on Pt sites. Hydrogen spillover offers a promising solution to deliver...
Background: Loeys-Dietz syndrome (LDS) is a type of connective tissue disease with systemic symptoms similar to Marfan syndrome. Ocular findings are rarely reported especially fundus and extraocular muscles. Case presentation: A 6-month old boy with systemic skeletal development delay was found peripheral non-perfusion and neovascularization in the both eyes, and gaven intravitreal injection of ranibizumab and laser. Fundus examination revealed a mild straightening of the temporal vessel in the both eyes. A 22-month old girl with confirmed connective tissue disorder presented to our hospital for strabismus and showed congenital hypoplasia of extraocular muscles. She also had arteriovenous anastomosis in the retinal. The diagnosis of LDS was supported by the genetic DNA examination. Conclusion: His is the first report of LDS with congenital hypoplasia of extraocular muscles, meanwhile, ocular examination especially fundus should be paid attention to.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
