Single Pt atom catalysts are key targets because a high exposure of substantially enhances electrocatalytic activity. In addition, PtRu alloy nanoparticles the most active for methanol oxidation reaction. To combine exceptional activity single with an Ru support we must overcome synthetic challenge forming atoms on noble metal nanoparticles. Here demonstrate process that grows and spreads islan...

Increasing consumption produces a large amount of cotton textile waste, the conversion which into porous metals used for energy purposes is practical value. In this paper, porous, Ni-based, hollow microtubular weave (Ni-HTW) obtained from by high-temperature carbonization and hydrothermal synthesis with reduction. The microtubules in have diameter 5–10 μm wall thickness about 1 μm, every 15 for...

We demonstrate electric power generation via the electrooxidation of ethylene glycol (EG) on a series of Fe-group nanoalloy (NA) catalysts in alkaline media. A series of Fe-group binary NA catalysts supported on carbon (FeCo/C, FeNi/C, and CoNi/C) and monometallic analogues (Fe/C, Co/C, and Ni/C) were synthesized. Catalytic activities and product distributions on the prepared Fe-group NA cataly...

Electrochemical oxidation of small molecules (e.g., water, urea, methanol, hydrazine, and glycerol) has gained growing scientific interest in the fields electrochemical energy conversion/storage environmental remediation. Designing cost-effective catalysts for electrooxidation (ESM) is thus crucial improving reaction efficiency. Recently, earth-abundant amorphous transition metal (TM)-based nan...

Atomically dispersed metals maximize the number of catalytic sites and enhance their activity. However, challenging synthesis characterization strongly complicates optimization. Here, aim is to demonstrate that tuning electronic environment atomically metal catalysts through modification edge coordination an effective strategy performance. This article focuses on optimizing nickel-based electro...

A simple and facile method was developed to prepare fluorescent carbon nanocrystals (CNCs) with low cytotoxicity and no photobleaching, by electrooxidation of graphite in aqueous solution.
