Nonequilibrium-corrosive engineering synthesis of Pt anchored on FeO with oxygen vacancy for efficient electrocatalytic hydrogen evolution reaction.

The development of suitable support to maximize the atomic utilization efficiency of platinum is of great significance for the hydrogen evolution reaction (HER). Herein, we report a simple and fast nonequilibrium-corrosive approach to prepare oxygen defect-enriched FeO decorated with trace Pt onto nickel-iron foam (Pt/FeO-O/NIF). The Pt/FeO-O/NIF electrode is superhydrophilic with intimate contact with the electrolyte.

A Molecular-Sieving Interphase Towards Low-Concentrated Aqueous Sodium-Ion Batteries.

Aqueous sodium-ion batteries are known for poor rechargeability because of the competitive water decomposition reactions and the high electrode solubility. Improvements have been reported by salt-concentrated and organic-hybridized electrolyte designs, however, at the expense of cost and safety. Here, we report the prolonged cycling of ASIBs in routine dilute electrolytes by employing artificial electrode coatings consisting of NaX zeolite and NaOH-neutralized perfluorinated sulfonic polymer.

Acidic medium synthesis of zeolites - an avenue to control the structure-directing power of organic templates.

This paper deals with the extension of the synthesis field of microporous zeolite-type materials and types of organic structure-directing agents (OSDA) that can be used to promote their crystallization. The highly hydrophilic hexamethylenetetramine (urotropine), with its C/N ratio = 1.5, which is unusual to act as a structure-directing agent in the crystallization of open-framework silica polymorphs, is used to exemplify the novelty of the employed approach.
