Atomic layer deposition (ALD) of Pt using MeCpPtMe3 and the O-2/O-3/O-2-plasma (O-2*) at 300 degrees C is investigated with in vacuo X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) to gain a better understanding of the Pt growth mechanism. Most notably, the chemical state of the surface Pt atoms and the role of surface O ...

Although often overlooked, single-atom catalysts inevitably contain heterogeneous active sites and their structures can further change under reaction conditions. Here, we conduct rigorous in situ X-ray absorption spectroscopy with 1–10 wt% Pt on S-doped zeolite-templated carbon (SZTC) to elucidate their remarkable electrocatalytic H2O2 synthesis pr...
Since the application in fuel cell, the electrochemical adsorption of hydroxyl has received considerable attention in recent years. While most research mainly focus on the room temperature, in this paper, the electrochemical adsorption of hydroxyl in alkaline solution at high temperature was investigated. An unusual oxidation peak was observed at -...

Ultralow energy (ULE) ion implantation is being increasingly applied to the modification of 2D materials, in particular, for substitutional doping and intercalation of graphene. Implantation-induced defects, whether desired or not, have a strong impact on the properties of graphene. Significant research has been devoted to vacancy-related defects h...
Realizing the neurological information processing by analyzing the complex data transferring behavior of populations and individual neurons is one of the fast-growing fields of neuroscience and bioelectronic technologies. This field is anticipated to cover a wide range of advanced applications, including neural dynamic monitoring, understanding the...
The development of highly-active electrocatalysts and identification of active sites contribution are necessary for electrocatalytic hydrogenation (ECH) of bio-oil. Herein, the Pt-decorated shrimp shell biochar (SSB) catalysts with high nitrogen content was prepared successfully. The biochar-based catalysts were first used for the ECH of bio-oil mo...
