Upgrading overall water splitting (OWS) system and developing high‐performance electrocatalysts is an attractive way to the improve efficiency and reduce the consumption of hydrogen (H2) production from electrolyzed water. Here, a Pt cluster/Ir metallene heterojunction structure (Pt/Ir hetero‐metallene) with a unique Pt/Ir interface is reported for the conversion of ethylene glycol (EG) to glycolic...
Amorphous/crystalline (a/c) hetero‐phase structures are considered as a class of efficient electrocatalysts for hydrogen evolution reaction (HER), but it remains a substantial challenge to obtain the specific phase by phase‐selective synthesis. In this work, a general route for the preparation of various heterogeneous aerogels (RuB, PtB, PdB, and RhB) consisting of amorphous and crystalline phases...
Developing stable silicon‐based and lithium metal anodes still faces many challenges. Designing new highly practical silicon‐based anodes with low‐volume expansion and high electrical conductivity, and inhibiting lithium dendrite growth are avenues for developing silicon‐based and lithium metal anodes, respectively. In this study, SiOxCy microtubes are synthesized using a chemical vapor deposition...
The utilization of thermodynamically favorable sulfur oxidation reaction (SOR) as an alternative to sluggish oxygen evolution reaction is a promising technology for low‐energy H2 production while degrading the sulfur source from wastewater. Herein, amorphous/crystalline S‐doped Pd nanosheet arrays on nickel foam (a/c S‐Pd NSA/NF) is prepared by S‐doping crystalline Pd NSA/NF. Owing to the ultrathin...
Tailoring the morphology and crystal structure of metallene is critical to improve its electrocatalytic performance. In this work, hetero‐phase RhB metallene (h‐RhB metallene) with amorphous/crystalline structure is readily prepared by a two‐step method. The h‐RhB metallene is very unique in its non‐metallic heteroatom doping and amorphous/crystalline structure. Benefiting from the unique metallene...
It is still a great challenge to explore hydrogen evolution reaction (HER) electrocatalysts with both lower overpotential and higher stability in acidic electrolytes. In this work, an efficient HER catalyst, Ru@COF‐1, is prepared by complexation of triazine‐cored sp2 carbon‐conjugated covalent organic frameworks (COFs) with ruthenium ion. Ru@COF‐1 possesses high crystallinity and porosity, which are...
In article number 1800573 by Xin Lou and co‐workers, an αvβ3‐specific Fe3O4‐RGD nanoprobe is prepared for in vivo magnetic resonance imaging of the collaterals after cerebral ischemia, and shows the binding specificity to the cerebral collaterals. The direct observation of cerebral collaterals is enabled in a quasi‐real time fashion, and further studies are also performed to show the collateral dynamics...
Ischemic stroke is one of the major leading causes for long‐term disability and mortality. Collateral vessels provide an alternative pathway to protect the brain against ischemic injury after arterial occlusion. Aiming at visualizing the collaterals occurring during acute ischemic stroke, an integrin αvβ3‐specific Fe3O4–Arg‐Gly‐Asp (RGD) nanoprobe is prepared for magnetic resonance imaging (MRI) of...
